## What's Hurl? {#introduction-home-whats-hurl}

Hurl is a command line tool that runs <b>HTTP requests</b> defined in a simple <b>plain text format</b>.

It can chain requests, capture values and evaluate queries on headers and body response. Hurl is very
versatile: it can be used for both <b>fetching data</b> and <b>testing HTTP</b> sessions.

Hurl makes it easy to work with <b>HTML</b> content, <b>REST / SOAP / GraphQL</b> APIs, or any other <b>XML / JSON</b> based APIs. 

```hurl
# Go home and capture token
GET https://example.org
HTTP 200
[Captures]
csrf_token: xpath "string(//meta[@name='_csrf_token']/@content)"


# Do login!
POST https://example.org/login
[Form]
user: toto
password: 1234
token: {{csrf_token}}
HTTP 302
```

Chaining multiple requests is easy:

```hurl
GET https://example.org/api/health
GET https://example.org/api/step1
GET https://example.org/api/step2
GET https://example.org/api/step3
```

## Also an HTTP Test Tool {#introduction-home-also-an-http-test-tool}

Hurl can run HTTP requests but can also be used to <b>test HTTP responses</b>.
Different types of queries and predicates are supported, from [XPath](https://en.wikipedia.org/wiki/XPath) and [JSONPath](https://goessner.net/articles/JsonPath/) on body response,
to assert on status code and response headers.



It is well adapted for <b>REST / JSON APIs</b>

```hurl
POST https://example.org/api/tests
{
    "id": "4568",
    "evaluate": true
}
HTTP 200
[Asserts]
header "X-Frame-Options" == "SAMEORIGIN"
jsonpath "$.status" == "RUNNING"    # Check the status code
jsonpath "$.tests" count == 25      # Check the number of items
jsonpath "$.id" matches /\d{4}/     # Check the format of the id
```

<b>HTML content</b>

```hurl
GET https://example.org
HTTP 200
[Asserts]
xpath "normalize-space(//head/title)" == "Hello world!"
```

<b>GraphQL</b> 

~~~hurl
POST https://example.org/graphql
```graphql
{
  human(id: "1000") {
    name
    height(unit: FOOT)
  }
}
```
HTTP 200
~~~

and even <b>SOAP APIs</b>

```hurl
POST https://example.org/InStock
Content-Type: application/soap+xml; charset=utf-8
SOAPAction: "http://www.w3.org/2003/05/soap-envelope"
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:m="https://example.org">
  <soap:Header></soap:Header>
  <soap:Body>
    <m:GetStockPrice>
      <m:StockName>GOOG</m:StockName>
    </m:GetStockPrice>
  </soap:Body>
</soap:Envelope>
HTTP 200
```

Hurl can also be used to test the <b>performance</b> of HTTP endpoints

```hurl
GET https://example.org/api/v1/pets
HTTP 200
[Asserts]
duration < 1000  # Duration in ms
```

And check response bytes

```hurl
GET https://example.org/data.tar.gz
HTTP 200
[Asserts]
sha256 == hex,039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81;
```

Finally, Hurl is easy to <b>integrate in CI/CD</b>, with text, JUnit, TAP and HTML reports

## Why Hurl? {#introduction-home-why-hurl}

<ul class="showcase-container">
    <li class="showcase-item"><h2 class="showcase-item-title">Text Format</h2>For both devops and developers</li>
    <li class="showcase-item"><h2 class="showcase-item-title">Fast CLI</h2>A command line for local dev and continuous integration</li>
    <li class="showcase-item"><h2 class="showcase-item-title">Single Binary</h2>Easy to install, with no runtime required</li>
</ul>

## Powered by curl {#introduction-home-powered-by-curl}

Hurl is a lightweight binary written in [Rust](https://www.rust-lang.org). Under the hood, Hurl HTTP engine is
powered by [libcurl](https://curl.se/libcurl/), one of the most powerful and reliable file transfer libraries.
With its text file format, Hurl adds syntactic sugar to run and test HTTP requests,
but it's still the [curl](https://curl.se) that we love: __fast__, __efficient__ and __IPv6 / HTTP/3 ready__.

## Feedbacks {#introduction-home-feedbacks}

To support its development, [star Hurl on GitHub](https://github.com/Orange-OpenSource/hurl/stargazers)!

[Feedback, suggestion, bugs or improvements](https://github.com/Orange-OpenSource/hurl/issues) are welcome.

```hurl

## Manual {#getting-started-manual-manual}

### Name {#getting-started-manual-name}

hurl - run and test HTTP requests.

### Synopsis {#getting-started-manual-synopsis}

**hurl** [OPTIONS] [FILES...]

**hurl** --test [OPTIONS] [FILES...]

### Description {#getting-started-manual-description}

**Hurl** is a command line tool that runs HTTP requests defined in a simple plain text format.

It can chain requests, capture values and evaluate queries on headers and body response. Hurl is very versatile, it can be used for fetching data and testing HTTP sessions: HTML content, REST / SOAP / GraphQL APIs, or any other XML / JSON based APIs.

```shell
$ hurl session.hurl
```

If no input files are specified, input is read from stdin.

```shell
$ echo GET http://httpbin.org/get | hurl
    {
      "args": {},
      "headers": {
        "Accept": "*/*",
        "Accept-Encoding": "gzip",
        "Content-Length": "0",
        "Host": "httpbin.org",
        "User-Agent": "hurl/0.99.10",
        "X-Amzn-Trace-Id": "Root=1-5eedf4c7-520814d64e2f9249ea44e0"
      },
      "origin": "1.2.3.4",
      "url": "http://httpbin.org/get"
    }
```

Hurl can take files as input, or directories. In the latter case, Hurl will search files with `.hurl` extension recursively.

Output goes to stdout by default. To have output go to a file, use the [`-o, --output`](#getting-started-manual-output) option:

```shell
$ hurl -o output input.hurl
```

By default, Hurl executes all HTTP requests and outputs the response body of the last HTTP call.

To have a test oriented output, you can use [`--test`](#getting-started-manual-test) option:

```shell
$ hurl --test *.hurl
```


### Hurl File Format {#getting-started-manual-hurl-file-format}

The Hurl file format is fully documented in [https://hurl.dev/docs/hurl-file.html](https://hurl.dev/docs/hurl-file.html)

It consists of one or several HTTP requests

```hurl
GET http://example.org/endpoint1
GET http://example.org/endpoint2
```


#### Capturing values {#getting-started-manual-capturing-values}

A value from an HTTP response can be-reused for successive HTTP requests.

A typical example occurs with CSRF tokens.

```hurl
GET https://example.org
HTTP 200
# Capture the CSRF token value from html body.
[Captures]
csrf_token: xpath "normalize-space(//meta[@name='_csrf_token']/@content)"

# Do the login !
POST https://example.org/login?user=toto&password=1234
X-CSRF-TOKEN: {{csrf_token}}
```

More information on captures can be found here [https://hurl.dev/docs/capturing-response.html](https://hurl.dev/docs/capturing-response.html)

#### Asserts {#getting-started-manual-asserts}

The HTTP response defined in the Hurl file are used to make asserts. Responses are optional.

At the minimum, response includes assert on the HTTP status code.

```hurl
GET http://example.org
HTTP 301
```

It can also include asserts on the response headers

```hurl
GET http://example.org
HTTP 301
Location: http://www.example.org
```

Explicit asserts can be included by combining a query and a predicate

```hurl
GET http://example.org
HTTP 301
[Asserts]
xpath "string(//title)" == "301 Moved"
```

With the addition of asserts, Hurl can be used as a testing tool to run scenarios.

More information on asserts can be found here [https://hurl.dev/docs/asserting-response.html](https://hurl.dev/docs/asserting-response.html)

### Configuration {#getting-started-manual-configuration}

Options that exist in curl have exactly the same semantics.

Options specified on the command line are defined for every Hurl file's entry,
except if they are tagged as cli-only (can not be defined in the Hurl request `[Options]` entry)

For instance:

```shell
$ hurl --location foo.hurl
```

will follow redirection for each entry in `foo.hurl`. You can also define an option only for a particular entry with an `[Options]` section. For instance, this Hurl file:

```hurl
GET https://example.org
HTTP 301

GET https://example.org
[Options]
location: true
HTTP 200
```

will follow a redirection only for the second entry.

Most of the options can also be defined with environment variables (like `HURL_INSECURE` for [`--insecure`](#getting-started-manual-insecure)). So, in order
to configure Hurl, there are three sources from the lowest priority (most easily overridden) to highest (overrides all others):

- Environment variables (ex: `HURL_INSECURE`)
- Command-line options (ex: `--insecure`)
- Options section options (ex: `insecure: true` in file)

### All Options {#getting-started-manual-all-options}

## Samples {#getting-started-samples-samples}

To run a sample, edit a file with the sample content, and run Hurl:

```shell
$ vi sample.hurl

GET https://example.org

$ hurl sample.hurl
```

By default, Hurl behaves like [curl](https://curl.se) and outputs the last HTTP response's [entry](#file-format-entry). To have a test
oriented output, you can use [`--test` option](#getting-started-manual-test):

```shell
$ hurl --test sample.hurl
```

A particular response can be saved with [`[Options] section`](#file-format-request-options):

```hurl
GET https://example.ord/cats/123
[Options]
output: cat123.txt    # use - to output to stdout
HTTP 200

GET https://example.ord/dogs/567
HTTP 200
```

Finally, Hurl can take files as input, or directories. In the latter case, Hurl will search files with `.hurl` extension recursively.

```shell
$ hurl --test integration/*.hurl
$ hurl --test .
```

You can check [Hurl tests suite](https://github.com/Orange-OpenSource/hurl/tree/master/integration/hurl/tests_ok) for more samples.

### Getting Data {#getting-started-samples-getting-data}

A simple GET:

```hurl
GET https://example.org
```

Requests can be chained:

```hurl
GET https://example.org/a
GET https://example.org/b
HEAD https://example.org/c
GET https://example.org/c
```

[Doc](#file-format-request-method)

#### HTTP Headers {#getting-started-samples-http-headers}

A simple GET with headers:

```hurl
GET https://example.org/news
User-Agent: Mozilla/5.0 
Accept: */*
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
```

[Doc](#file-format-request-headers)

#### Query Params {#getting-started-samples-query-params}

```hurl
GET https://example.org/news
[Query]
order: newest
search: something to search
count: 100
```

Or:

```hurl
GET https://example.org/news?order=newest&search=something%20to%20search&count=100
```

> With `[Query]` section, params don't need to be URL escaped.

[Doc](#file-format-request-query-parameters)

#### Basic Authentication {#getting-started-samples-basic-authentication}

```hurl
GET https://example.org/protected
[BasicAuth]
bob: secret
```

[Doc](#file-format-request-basic-authentication)

This is equivalent to construct the request with a [Authorization](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Authorization) header:

```hurl
# Authorization header value can be computed with `echo -n 'bob:secret' | base64`
GET https://example.org/protected
Authorization: Basic Ym9iOnNlY3JldA== 
```

Basic authentication section allows per request authentication. If you want to add basic authentication to all the
requests of a Hurl file you could use [`-u/--user` option](#getting-started-manual-user):

```shell
$ hurl --user bob:secret login.hurl
```

[`--user`](#getting-started-manual-user) option can also be set per request:

```hurl
GET https://example.org/login
[Options]
user: bob:secret
HTTP 200

GET https://example.org/login
[Options]
user: alice:secret
HTTP 200
```

#### Passing Data between Requests  {#getting-started-samples-passing-data-between-requests}

[Captures](#file-format-capturing-response) can be used to pass data from one request to another:

```hurl
POST https://sample.org/orders
HTTP 201
[Captures]
order_id: jsonpath "$.order.id"

GET https://sample.org/orders/{{order_id}}
HTTP 200
```

[Doc](#file-format-capturing-response)

### Sending Data {#getting-started-samples-sending-data}

#### Sending HTML Form Data {#getting-started-samples-sending-html-form-data}

```hurl
POST https://example.org/contact
[Form]
default: false
token: {{token}}
email: john.doe@rookie.org
number: 33611223344
```

[Doc](#file-format-request-form-parameters)

#### Sending Multipart Form Data {#getting-started-samples-sending-multipart-form-data}

```hurl
POST https://example.org/upload
[Multipart]
field1: value1
field2: file,example.txt;
# One can specify the file content type:
field3: file,example.zip; application/zip
```

[Doc](#file-format-request-multipart-form-data)

Multipart forms can also be sent with a [multiline string body](#file-format-request-multiline-string-body):

~~~hurl
POST https://example.org/upload
Content-Type: multipart/form-data; boundary="boundary"
```
--boundary
Content-Disposition: form-data; name="key1"

value1
--boundary
Content-Disposition: form-data; name="upload1"; filename="data.txt"
Content-Type: text/plain

Hello World!
--boundary
Content-Disposition: form-data; name="upload2"; filename="data.html"
Content-Type: text/html

<div>Hello <b>World</b>!</div>
--boundary--
```
~~~

In that case, files have to be inlined in the Hurl file.

[Doc](#file-format-request-multiline-string-body)

#### Posting a JSON Body {#getting-started-samples-posting-a-json-body}

With an inline JSON:

```hurl
POST https://example.org/api/tests
{
    "id": "456",
    "evaluate": true
}
```

[Doc](#file-format-request-json-body)

With a local file:

```hurl
POST https://example.org/api/tests
Content-Type: application/json
file,data.json;
```

[Doc](#file-format-request-file-body)

#### Templating a JSON Body {#getting-started-samples-templating-a-json-body}

```hurl
PUT https://example.org/api/hits
Content-Type: application/json
{
    "key0": "{{a_string}}",
    "key1": {{a_bool}},
    "key2": {{a_null}},
    "key3": {{a_number}}
}
```

Variables can be initialized via command line:

```shell
$ hurl --variable a_string=apple \
       --variable a_bool=true \
       --variable a_null=null \
       --variable a_number=42 \
       test.hurl
```

Resulting in a PUT request with the following JSON body:

```
{
    "key0": "apple",
    "key1": true,
    "key2": null,
    "key3": 42
}
```

[Doc](#file-format-templates)

#### Templating a XML Body {#getting-started-samples-templating-a-xml-body}

Using templates with [XML body](#file-format-request-xml-body) is not currently supported in Hurl. You can use templates in
[XML multiline string body](#file-format-request-multiline-string-body) with variables to send a variable XML body:

~~~hurl
POST https://example.org/echo/post/xml
```xml
<?xml version="1.0" encoding="utf-8"?>
<Request>
    <Login>{{login}}</Login>
    <Password>{{password}}</Password>
</Request>
```
~~~

[Doc](#file-format-request-multiline-string-body)

#### Using GraphQL Query {#getting-started-samples-using-graphql-query}

A simple GraphQL query:

~~~hurl
POST https://example.org/starwars/graphql
```graphql
{
  human(id: "1000") {
    name
    height(unit: FOOT)
  }
}
```
~~~

A GraphQL query with variables:

~~~hurl
POST https://example.org/starwars/graphql
```graphql
query Hero($episode: Episode, $withFriends: Boolean!) {
  hero(episode: $episode) {
    name
    friends @include(if: $withFriends) {
      name
    }
  }
}

variables {
  "episode": "JEDI",
  "withFriends": false
}
```
~~~

GraphQL queries can also use [Hurl templates](#file-format-templates).

[Doc](#file-format-request-graphql-body)

#### Using Dynamic Datas {#getting-started-samples-using-dynamic-datas}

[Functions](#file-format-templates-functions) like `newUuid` and `newDate` can be used in templates to create dynamic datas:


A file that creates a dynamic email (i.e `0531f78f-7f87-44be-a7f2-969a1c4e6d97@test.com`):

```hurl
POST https://example.org/api/foo
{
  "name": "foo",
  "email": "{{newUuid}}@test.com"
}
```

A file that creates a dynamic query parameter (i.e `2024-12-02T10:35:44.461731Z`):

```hurl
GET https://example.org/api/foo
[Query]
date: {{newDate}}
HTTP 200
```

[Doc](#file-format-templates-functions)

### Testing Response {#getting-started-samples-testing-response}

Responses are optional, everything after `HTTP` is part of the response asserts.

```hurl
# A request with (almost) no check:
GET https://foo.com

# A status code check:
GET https://foo.com
HTTP 200

# A test on response body
GET https://foo.com
HTTP 200
[Asserts]
jsonpath "$.state" == "running"
```

#### Testing Status Code {#getting-started-samples-testing-status-code}

```hurl
GET https://example.org/order/435
HTTP 200
```

[Doc](#file-format-asserting-response-version-status)

```hurl
GET https://example.org/order/435
# Testing status code is in a 200-300 range
HTTP *
[Asserts]
status >= 200
status < 300
```

[Doc](#file-format-asserting-response-status-assert)

#### Testing Response Headers {#getting-started-samples-testing-response-headers}

Use implicit response asserts to test header values:

```hurl
GET https://example.org/index.html
HTTP 200
Set-Cookie: theme=light
Set-Cookie: sessionToken=abc123; Expires=Wed, 09 Jun 2021 10:18:14 GMT
```

[Doc](#file-format-asserting-response-headers)


Or use explicit response asserts with [predicates](#file-format-asserting-response-predicates):

```hurl
GET https://example.org
HTTP 302
[Asserts]
header "Location" contains "www.example.net"
```

[Doc](#file-format-asserting-response-header-assert)

Implicit and explicit asserts can be combined:

```hurl
GET https://example.org/index.html
HTTP 200
Set-Cookie: theme=light
Set-Cookie: sessionToken=abc123; Expires=Wed, 09 Jun 2021 10:18:14 GMT
[Asserts]
header "Location" contains "www.example.net"
```

#### Testing REST APIs {#getting-started-samples-testing-rest-apis}

Asserting JSON body response (node values, collection count etc...) with [JSONPath](https://goessner.net/articles/JsonPath/):

```hurl

screencapability: low
HTTP 200
[Asserts]
jsonpath "$.validated" == true
jsonpath "$.userInfo" isObject
jsonpath "$.userInfo.firstName" == "Franck"
jsonpath "$.userInfo.lastName" == "Herbert"
jsonpath "$.hasDevice" == false

xpath "count(//p)" == 2  # Check the number of p
xpath "//p" count == 2  # Similar assert for p
xpath "boolean(count(//h2))" == false  # Check there is no h2  
xpath "//h2" not exists  # Similar assert for h2
xpath "string(//div[1])" matches /Hello.*/
```

[Asserts]
sha256 == hex,039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81;
```

[Doc](#file-format-asserting-response-sha-256-assert)

#### SSL Certificate {#getting-started-samples-ssl-certificate}

Check the properties of a SSL certificate:

```hurl
GET https://example.org
HTTP 200
[Asserts]
certificate "Subject" == "CN=example.org"
certificate "Issuer" == "C=US, O=Let's Encrypt, CN=R3"
certificate "Expire-Date" daysAfterNow > 15
certificate "Serial-Number" matches /[\da-f]+/
certificate "Subject-Alt-Name" contains "DNS:example.org"
certificate "Subject-Alt-Name" split "," count == 2
```

[Doc](#file-format-asserting-response-ssl-certificate-assert)

#### Checking Full Body {#getting-started-samples-checking-full-body}

Use implicit body to test an exact JSON body match:

```hurl
GET https://example.org/api/cats/123
HTTP 200
{
  "name" : "Purrsloud",
  "species" : "Cat",
  "favFoods" : ["wet food", "dry food", "<strong>any</strong> food"],
  "birthYear" : 2016,
  "photo" : "https://learnwebcode.github.io/json-example/images/cat-2.jpg"
}
```

[Doc](#file-format-asserting-response-json-body)

Or an explicit assert file:

```hurl
GET https://example.org/index.html
HTTP 200
[Asserts]
body == file,cat.json;
```

[Doc](#file-format-asserting-response-body-assert)

Implicit asserts supports XML body:

```hurl
GET https://example.org/api/catalog
HTTP 200
<?xml version="1.0" encoding="UTF-8"?>

#### Testing Redirections {#getting-started-samples-testing-redirections}

By default, Hurl doesn't follow redirection so each step of a redirect must be run manually and can be analysed:

```hurl
GET https://example.org/step1
HTTP 301
[Asserts]
header "Location" == "https://example.org/step2"


GET https://example.org/step2
HTTP 301
[Asserts]
header "Location" == "https://example.org/step3"


GET https://example.org/step3
HTTP 200
```

[Doc](#file-format-asserting-response)

Using [`--location`](#getting-started-manual-location) and [`--location-trusted`](#getting-started-manual-location-trusted) (either with command line option or per request), Hurl follows 
redirection and each step of the redirection can be checked.

```hurl
GET https://example.org/step1
[Options]
location: true
HTTP 200
[Asserts]
redirects count == 2
redirects nth 0 location == "https://example.org/step2"
redirects nth 1 location == "https://example.org/step3"
```

```hurl
GET https://example.org/step1
[Options]
location-trusted: true
HTTP 200
[Asserts]
redirects last location == "https://example.org/step2"
```

[Doc](#file-format-asserting-response-redirects-assert)

#### AWS Signature Version 4 Requests {#getting-started-samples-aws-signature-version-4-requests}

Generate signed API requests with [AWS Signature Version 4](https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html), as used by several cloud providers.

```hurl
POST https://sts.eu-central-1.amazonaws.com/
[Options]
aws-sigv4: aws:amz:eu-central-1:sts
[Form]
Action: GetCallerIdentity
Version: 2011-06-15

```hurl
POST https://sts.eu-central-1.amazonaws.com/
[Options]
aws-sigv4: aws:amz:eu-central-1:sts
user: bob=secret
[Form]
Action: GetCallerIdentity
Version: 2011-06-15
```

[Doc](#getting-started-manual-aws-sigv4)

#### Using curl Options {#getting-started-samples-using-curl-options}

curl options (for instance [`--resolve`](#getting-started-manual-resolve) or [`--connect-to`](#getting-started-manual-connect-to)) can be used as CLI argument. In this case, they're applicable
to each request of an Hurl file.

```shell
$ hurl --resolve foo.com:8000:127.0.0.1 foo.hurl
```

Use  [`[Options]` section](#file-format-request-options) to configure a specific request:

```hurl
GET http://bar.com
HTTP 200


GET http://foo.com:8000/resolve
[Options]
resolve: foo.com:8000:127.0.0.1
HTTP 200
`Hello World!`
```

[Doc](#file-format-request-options)




<hr>

## Running Tests {#getting-started-running-tests-running-tests}

### Use --test Option {#getting-started-running-tests-use-test-option}

Hurl is run by default as an HTTP client, returning the body of the last HTTP response.

```shell
$ hurl hello.hurl
Hello World!
```

When multiple input files are provided, Hurl outputs the body of the last HTTP response of each file.

```shell
$ hurl hello.hurl assert_json.hurl
Hello World![
  { "id": 1, "name": "Bob"},
  { "id": 2, "name": "Bill"}
]
```

For testing, we are only interested in the asserts results, we don't need the HTTP body response. To use Hurl as a 
test tool with an adapted output, you can use [`--test` option](#getting-started-manual-test):

```shell
$ hurl --test hello.hurl assert_json.hurl
hello.hurl: Success (6 request(s) in 245 ms)
assert_json.hurl: Success (8 request(s) in 308 ms)
--------------------------------------------------------------------------------
Executed files:    2
Executed requests: 10 (17.82/s)
Succeeded files:   2 (100.0%)
Failed files:      0 (0.0%)
Duration:          561 ms
```

Or, in case of errors:

```shell
$ hurl --test hello.hurl error_assert_status.hurl 
hello.hurl: Success (4 request(s) in 5 ms)
error: Assert status code
  --> error_assert_status.hurl:9:6
   |
   | GET http://localhost:8000/not_found
   | ...
 9 | HTTP 200
   |      ^^^ actual value is <404>
   |

error_assert_status.hurl: Failure (1 request(s) in 2 ms)
--------------------------------------------------------------------------------
Executed files:    2
Executed requests: 5 (500.0/s)
Succeeded files:   1 (50.0%)
Failed files:      1 (50.0%)
Duration:          10 ms
```

> With or without `--test`, all asserts are always executed. `--test` adds a run recap and disables the output of the 
> last response. To ignore asserts execution, you can use [`--ignore-asserts`](#getting-started-manual-ignore-asserts).

In test mode, files are executed in parallel to speed-ud the execution. If a sequential run is needed, you can use
[`--jobs 1`](#getting-started-manual-jobs) option to execute tests one by one.

```shell
$ hurl --test --jobs 1 *.hurl
```

[`--repeat` option](#getting-started-manual-repeat) can be used to repeat run files and do [performance check](#getting-started-running-tests-stress-and-performance-tests). For instance, this call will run 1000 tests
in parallel:

```shell
$ hurl --test --repeat 1000 stress.hurl
```


#### Selecting Tests {#getting-started-running-tests-selecting-tests}

Hurl can take multiple files into inputs:

```shell
$ hurl --test test/integration/a.hurl test/integration/b.hurl test/integration/c.hurl 
```

```shell
$ hurl --test test/integration/*.hurl 
```

Or you can simply give a directory and Hurl will find files with `.hurl` extension recursively:

```shell
$ hurl --test test/integration/
```

Finally, you can use [`--glob` option](#getting-started-manual-glob) to test files that match a given pattern:

```shell
$ hurl --test --glob "test/integration/**/*.hurl"
```

### Debugging {#getting-started-running-tests-debugging}

#### Debug Logs {#getting-started-running-tests-debug-logs}

If you need more error context, you can use [`--error-format long` option](#getting-started-manual-error-format) to print HTTP bodies for failed asserts:

```shell
$ hurl --test --error-format long hello.hurl error_assert_status.hurl 
hello.hurl: Success (4 request(s) in 6 ms)
HTTP/1.1 404
Server: Werkzeug/3.0.3 Python/3.12.4

<p>The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.</p>


error: Assert status code
  --> error_assert_status.hurl:9:6
   |
   | GET http://localhost:8000/not_found
   | ...
 9 | HTTP 200
   |      ^^^ actual value is <404>
   |

error_assert_status.hurl: Failure (1 request(s) in 2 ms)
--------------------------------------------------------------------------------
Executed files:    2
Executed requests: 5 (454.5/s)
Succeeded files:   1 (50.0%)
Failed files:      1 (50.0%)
Duration:          11 ms
```

Individual requests can be modified with [`[Options]` section][options](#file-format-request-options) to turn on logs for a particular request, using
[`verbose`](#getting-started-manual-verbose) and [`very-verbose`](#getting-started-manual-very-verbose) option. 

With this Hurl file:

```hurl
GET https://foo.com
HTTP 200

GET https://bar.com
[Options]
very-verbose: true
HTTP 200

GET https://baz.com
HTTP 200
```

Running `hurl --test .` will output debug logs for the request to `https://bar.com`.

[`--verbose`](#getting-started-manual-verbose) / [`--very-verbose`](#getting-started-manual-very-verbose) can also be enabled globally, for every requests of every tested files:

```shell
$ hurl --test --very-verbose .
```

#### HTTP Responses {#getting-started-running-tests-http-responses}

In test mode, HTTP responses are not displayed. One way to get HTTP responses even in test mode is to use 
[`--output` option](#getting-started-manual-output) of `[Options]` section: `--output file` allows to save a particular response to a file, while 
`--output -` allows to redirect HTTP responses to standard output.

```hurl
GET http://foo.com
HTTP 200

GET https://bar.com
[Options]
output: -
HTTP 200
```

```shell
$ hurl --test .
<html><head><meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>301 Moved</TITLE></head><body>
<h1>301 Moved</h1>
The document has moved
<a HREF="https://www.bar.com/">here</a>.
</body></html>
/tmp/test.hurl: Success (2 request(s) in 184 ms)
--------------------------------------------------------------------------------
Executed files:    1
Executed requests: 2 (10.7/s)
Succeeded files:   1 (100.0%)
Failed files:      0 (0.0%)
Duration:          187 ms
```

### Stress and Performance Tests {#getting-started-running-tests-stress-and-performance-tests}

Hurl can be used to perform stress tests:

- with [query duration](#file-format-asserting-response-duration-assert):

```hurl
GET https://example.org/foo
HTTP 200
[Asserts]
duration < 1200
```

- [response metrics](#file-format-response-timings) with [`--very-verbose`](#getting-started-manual-very-verbose) or [`--json`](#getting-started-manual-json) to get structured timing data:

```shell
$ hurl --json foo.hurl | jq
...
          "timings": {
            "app_connect": 0,
            "begin_call": "2025-10-06T07:00:57.127794Z",
            "connect": 120915,
            "end_call": "2025-10-06T07:00:57.280724Z",
            "name_lookup": 92987,
            "pre_transfer": 121014,
            "start_transfer": 152721,
            "total": 152807
          }
...
```

In performance uses-cases, it's important to know how Hurl is working to get the best request per second load. Each Hurl file 
is processed by its own libcurl instance (roughly speaking a living HTTP connection). Let's say we want to stress our 
application with 100,000 HTTP requests and see how it's behaving. The simplest idea would be to make a single Hurl file 
repeating 100,000 requests:

```hurl
GET https://my-website/health
[Options]
repeat: 100000
```

and run it:

```shell
$ hurl --test perf.hurl
```

With a single Hurl file, we won't benefit from any parallel runs (files are run in parallel, requests _within_ a file are
run sequentially). To benefit from parallel run, we can use [`--repeat`](#getting-started-manual-repeat) as a CLI argument to repeat file execution. It's 
as if we've written 100,000 identical Hurl files and run them:


```hurl
GET https://my-website/health
```

and run it:

```shell
$ hurl --test --repeat 100000 perf.hurl
```

In this case, we're running 100,000 Hurl files in parallel. Now, we have another problem: as each file is basically a
HTTP connection, we can run out of TCP port, a phenomenon known as [ephemeral ports exhaustion](https://blog.cloudflare.com/how-to-stop-running-out-of-ephemeral-ports-and-start-to-love-long-lived-connections/). So, to recap:

- running 100,000 requests in a single file won't benefit from parallel run
- running 100,000 one request files can lead to TCP port resources issues

The solution is to combine the two approaches: running 10 files of 10,000 HTTP requests. With 10 files of 10,000
requests, we're going to execute those files in parallel in their own worker. Each worker will be working sequentially, 
maximizing the usage and not running into TCP ports exhaustion. We can force jobs count to be exactly 10 so 
all workers start at the same time and no one is waiting to get a job done:

```hurl
GET https://my-website/health
[Options]
repeat: 10000
```

```shell
$ hurl --test --repeat 10 --jobs 10 perf.hurl
```



### Generating Report {#getting-started-running-tests-generating-report}

In the different reports, files are always referenced in the input order (which, as tests are executed in parallel, can 
be different from the execution order).

#### HTML Report {#getting-started-running-tests-html-report}

Hurl can generate an HTML report by using the [`--report-html DIR`](#getting-started-manual-report-html) option.

If the HTML report already exists, the test results will be appended to it.

<div class="picture">
    <img class="u-drop-shadow u-border u-max-width-100" src="https://hurl.dev/assets/img/hurl-html-report.png" width="670" alt="Hurl HTML Report">
</div>

The input Hurl files (HTML version) are also included and are easily accessed from the main page.

<div class="picture">
    <img class="u-drop-shadow u-border u-max-width-100" src="https://hurl.dev/assets/img/hurl-html-file.png" width="380" alt="Hurl HTML file">
</div>

#### JSON Report {#getting-started-running-tests-json-report}

A JSON report can be produced by using the [`--report-json DIR`](#getting-started-manual-report-json). The report directory will contain a `report.json` 
file, including each test file executed with [`--json`](#getting-started-manual-json) option and a reference to each HTTP response of the run dumped 
to disk.

If the JSON report already exists, it will be updated with the new test results.

#### JUnit Report {#getting-started-running-tests-junit-report}

A JUnit report can be produced by using the [`--report-junit FILE`](#getting-started-manual-report-junit) option.

If the JUnit report already exists, it will be updated with the new test results.

#### TAP Report {#getting-started-running-tests-tap-report}

A TAP report ([Test Anything Protocol](https://testanything.org)) can be produced by using the [`--report-tap FILE`](#getting-started-manual-report-tap) option.

If the TAP report already exists, it will be updated with the new test results.

### Use Variables in Tests {#getting-started-running-tests-use-variables-in-tests}

To use variables in your tests, you can:

- use [`--variable` option](#getting-started-manual-variable)
- use [`--variables-file` option](#getting-started-manual-variables-file)
- define environment variables, for instance `HURL_VARIABLE_foo=bar`

You will find a detailed description in the [Injecting Variables](#file-format-templates-injecting-variables) section of the docs.

## Frequently Asked Questions {#getting-started-frequently-asked-questions-frequently-asked-questions}

### General {#getting-started-frequently-asked-questions-general}

#### Why "Hurl"? {#getting-started-frequently-asked-questions-why-hurl}

The name Hurl is a tribute to the awesome [curl](https://curl.haxx.se), with a focus on the HTTP protocol.
While it may have an informal meaning not particularly elegant, [other eminent tools](https://git.wiki.kernel.org/index.php/GitFaq#Why_the_.27Git.27_name.3F) have set a precedent in naming.

#### Yet Another Tool, I already use X {#getting-started-frequently-asked-questions-yet-another-tool-i-already-use-x}

We think that Hurl has some advantages compared to similar tools.

Hurl is foremost a command line tool and should be easy to use on a local computer, or in a CI/CD pipeline. Some
tools in the same space as Hurl ([Postman](https://www.postman.com) for instance), are GUI oriented, and we find it
less attractive than CLI. As a command line tool, Hurl can be used to get HTTP data (like [curl](https://curl.haxx.se)),
but also as a test tool for HTTP sessions, or even as documentation.

Having a text based [file format](#file-format-hurl-file) is another advantage. The Hurl format is simple,
focused on the HTTP domain, can serve as documentation and can be read or written by non-technical people.

For instance putting JSON data with Hurl can be done with this simple file:

``` 
PUT http://localhost:3000/api/login
{
  "username": "xyz",
  "password": "xyz"
}
```

With [curl](https://curl.haxx.se):

```
curl --header "Content-Type: application/json" \
     --request PUT \
     --data '{"username": "xyz","password": "xyz"}' \
     http://localhost:3000/api/login
``` 


[Karate](https://github.com/intuit/karate), a tool combining API test automation, mocking, performance-testing, has
similar features but offers also much more at a cost of an increased complexity.

Comparing Karate file format:

```
Scenario: create and retrieve a cat

Given url 'http://myhost.com/v1/cats'
And request { name: 'Billie' }
When method post
Then status 201
And match response == { id: '#notnull', name: 'Billie }

Given path response.id
When method get
Then status 200
``` 

And Hurl:

```
# Scenario: create and retrieve a cat

POST http://myhost.com/v1/cats
{ "name": "Billie" }
HTTP 201
[Captures]
cat_id: jsonpath "$.id"
[Asserts]
jsonpath "$.name" == "Billie"

GET http://myshost.com/v1/cats/{{cat_id}}
HTTP 200
```

A key point of Hurl is to work on the HTTP domain. In particular, there is no JavaScript runtime, Hurl works on the
raw HTTP requests/responses, and not on a DOM managed by a HTML engine. For security, this can be seen as a feature:
let's say you want to test backend validation, you want to be able to bypass the browser or javascript validations and
directly test a backend endpoint.

Finally, with no headless browser and working on the raw HTTP data, Hurl is also
really reliable with a very small probability of false positives. Integration tests with tools like
[Selenium](https://www.selenium.dev) can, in this regard, be challenging to maintain.

Just use what is convenient for you. In our case, it's Hurl!

#### Hurl is build on top of libcurl, but what is added? {#getting-started-frequently-asked-questions-hurl-is-build-on-top-of-libcurl-but-what-is-added}

Hurl has two main functionalities on top of [curl](https://curl.haxx.se):

1. Chain several requests:

   With its [captures](#file-format-capturing-response), it enables to inject data received from a response into
   following requests. [CSRF tokens](https://en.wikipedia.org/wiki/Cross-site_request_forgery)
   are typical examples in a standard web session.

2. Test HTTP responses:

   With its [asserts](#file-format-asserting-response), responses can be easily tested.

Hurl benefits from the features of the `libcurl` against it is linked. You can check `libcurl` version with `hurl --version`.

For instance on macOS:

```shell
$ hurl --version
hurl 2.0.0 libcurl/7.79.1 (SecureTransport) LibreSSL/3.3.6 zlib/1.2.11 nghttp2/1.45.1
Features (libcurl):  alt-svc AsynchDNS HSTS HTTP2 IPv6 Largefile libz NTLM NTLM_WB SPNEGO SSL UnixSockets
Features (built-in): brotli
```

You can also check which `libcurl` is used.

On macOS:

```shell
$ which hurl
/opt/homebrew/bin/hurl
$ otool -L /opt/homebrew/bin/hurl:
	/usr/lib/libxml2.2.dylib (compatibility version 10.0.0, current version 10.9.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1858.112.0)
	/usr/lib/libcurl.4.dylib (compatibility version 7.0.0, current version 9.0.0)
	/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1311.100.3)
```

On Linux:

```shell
$ which hurl
/root/.cargo/bin/hurl
$ ldd /root/.cargo/bin/hurl
ldd /root/.cargo/bin/hurl
	linux-vdso.so.1 (0x0000ffff8656a000)
	libxml2.so.2 => /usr/lib/aarch64-linux-gnu/libxml2.so.2 (0x0000ffff85fe8000)
	libcurl.so.4 => /usr/lib/aarch64-linux-gnu/libcurl.so.4 (0x0000ffff85f45000)
	libgcc_s.so.1 => /lib/aarch64-linux-gnu/libgcc_s.so.1 (0x0000ffff85f21000)
	...
	libkeyutils.so.1 => /lib/aarch64-linux-gnu/libkeyutils.so.1 (0x0000ffff82ed5000)
	libffi.so.7 => /usr/lib/aarch64-linux-gnu/libffi.so.7 (0x0000ffff82ebc000)
```

Note that some Hurl features are dependent on `libcurl` capacities: for instance, if your `libcurl` doesn't support
HTTP/2 Hurl won't be able to send HTTP/2 request. 


#### Why shouldn't I use Hurl? {#getting-started-frequently-asked-questions-why-shouldnt-i-use-hurl}

If you need a GUI. Currently, Hurl does not offer a GUI version (like [Postman](https://www.postman.com)). While we
think that it can be useful, we prefer to focus for the time-being on the core, keeping something simple and fast.
Contributions to build a GUI are welcome.


#### I have a large numbers of tests, how to run just specific tests? {#getting-started-frequently-asked-questions-i-have-a-large-numbers-of-tests-how-to-run-just-specific-tests}

By convention, you can organize Hurl files into different folders or prefix them.

For example, you can split your tests into two folders critical and additional.

```
critical/test1.hurl
critical/test2.hurl
additional/test1.hurl
additional/test2.hurl
```

You can simply run your critical tests with

```shell
$ hurl --test critical/*.hurl
```

#### How can I use my Hurl files outside Hurl? {#getting-started-frequently-asked-questions-how-can-i-use-my-hurl-files-outside-hurl}

Hurl file can be exported to a JSON file with `hurlfmt`.
This JSON file can then be easily parsed for converting a different format, getting ad-hoc information,...

For example, the Hurl file

```hurl
GET https://example.org/api/users/1
User-Agent: Custom
HTTP 200
[Asserts]
jsonpath "$.name" == "Bob"
```

will be converted to JSON with the following command:

```shell
$ hurlfmt test.hurl --out json | jq
{
  "entries": [
    {
      "request": {
        "method": "GET",
        "url": "https://example.org/api/users/1",
        "headers": [
          {
            "name": "User-Agent",
            "value": "Custom"
          }
        ]
      },
      "response": {
        "version": "HTTP",
        "status": 200,
        "asserts": [
          {
            "query": {
              "type": "jsonpath",
              "expr": "$.name"
            },
            "predicate": {
              "type": "==",
              "value": "Bob"
            }
          }
        ]
      }
    }
  ]
}
```


#### Can I do calculation within a Hurl file? {#getting-started-frequently-asked-questions-can-i-do-calculation-within-a-hurl-file}

Currently, the templating is very simple, only accessing variables.
Calculations can be done beforehand, before running the Hurl File.

For example, with date calculations, variables `now` and `tomorrow` can be used as param or expected value.

```shell
$ TODAY=$(date '+%y%m%d')
$ TOMORROW=$(date '+%y%m%d' -d"+1days")
$ hurl --variable "today=$TODAY" --variable "tomorrow=$TOMORROW" test.hurl
```

You can also use environment variables that begins with `HURL_VARIABLE_` to inject data in an Hurl file.
For instance, to inject `today` and `tomorrow` variables:

```shell
$ export HURL_VARIABLE_today=$(date '+%y%m%d')
$ export HURL_VARIABLE_tomorrow=$(date '+%y%m%d' -d"+1days")
$ hurl test.hurl
```

You can also use [filters](#file-format-filters) to process HTTP responses in asserts and captures.

### macOS {#getting-started-frequently-asked-questions-macos}

#### How can I use a custom libcurl (from Homebrew by instance)? {#getting-started-frequently-asked-questions-how-can-i-use-a-custom-libcurl-from-homebrew-by-instance}

No matter how you've installed Hurl (using the precompiled binary for macOS or with [Homebrew](https://brew.sh))
Hurl is linked against the built-in system libcurl. If you want to use another libcurl (for instance,
if you've installed curl with Homebrew and want Hurl to use Homebrew's libcurl), you can patch Hurl with
the following command:

```shell
$ sudo install_name_tool -change /usr/lib/libcurl.4.dylib PATH_TO_CUSTOM_LIBCURL PATH_TO_HURL_BIN
```

For instance:

```shell
# /usr/local/opt/curl/lib/libcurl.4.dylib is installed by `brew install curl`
$ sudo install_name_tool -change /usr/lib/libcurl.4.dylib /usr/local/opt/curl/lib/libcurl.4.dylib /usr/local/bin/hurl
```



<hr>

# File Format {#file-format}

## Hurl File {#file-format-hurl-file-hurl-file}

### Character Encoding {#file-format-hurl-file-character-encoding}

Hurl file should be encoded in UTF-8, without a byte order mark at the beginning
(while Hurl ignores the presence of a byte order mark rather than treating it as an error)

### File Extension {#file-format-hurl-file-file-extension}

Hurl file extension is `.hurl`

### Comments {#file-format-hurl-file-comments}

Comments begin with `#` and continue until the end of line. Hurl file can serve as
a documentation for HTTP based workflows so it can be useful to be very descriptive.

```hurl
# A very simple Hurl file
# with tasty comments...
GET https://www.sample.net
x-app: MY_APP  # Add a dummy header
HTTP 302       # Check that we have a redirection
[Asserts]
header "Location" exists
header "Location" contains "login"  # Check that we are redirected to the login page
```

### Special Characters in Strings {#file-format-hurl-file-special-characters-in-strings}

String can include the following special characters:

- The escaped special characters \" (double quotation mark), \\ (backslash), \b (backspace), \f (form feed),
 \n (line feed), \r (carriage return), and \t (horizontal tab)
- An arbitrary Unicode scalar value, written as \u{n}, where n is a 1–8 digit hexadecimal number

```hurl
GET https://example.org/api
HTTP 200
# The following assert are equivalent:
[Asserts]
jsonpath "$.slideshow.title" == "A beautiful ✈!"
jsonpath "$.slideshow.title" == "A beautiful \u{2708}!"
```

In some case, (in headers value, etc..), you will also need to escape # to distinguish it from a comment.
In the following example:

```hurl
GET https://example.org/api
x-token: BEEF \#STEAK # Some comment
HTTP 200
```

We're sending a header `x-token` with value `BEEF #STEAK`



<hr>

## Entry {#file-format-entry-entry}

### Definition {#file-format-entry-definition}

A Hurl file is a list of entries, each entry being a mandatory [request](#file-format-request), optionally followed by a [response](#file-format-response).

Responses are not mandatory, a Hurl file consisting only of requests is perfectly valid. To sum up, responses can be used
to [capture values](#file-format-capturing-response) to perform subsequent requests, or [add asserts to HTTP responses](#file-format-asserting-response).

### Example {#file-format-entry-example}

```hurl
# First, test home title.
GET https://acmecorp.net
HTTP 200
[Asserts]
xpath "normalize-space(//head/title)" == "Hello world!"

# Get some news, response description is optional
GET https://acmecorp.net/news

# Do a POST request without CSRF token and check
# that status code is Forbidden 403
POST https://acmecorp.net/contact
[Form]
default: false
email: john.doe@rookie.org
number: 33611223344
HTTP 403
```

### Description {#file-format-entry-description}

#### Options {#file-format-entry-options}

[Options](#getting-started-manual-options) specified on the command line apply to every entry in an Hurl file. For instance, with [`--location` option](#getting-started-manual-location),
every entry of a given file will follow redirection:

```shell
$ hurl --location foo.hurl
```

You can use an [`[Options]` section][options](#file-format-request-options) to set option only for a specified request. For instance, in this Hurl file,
the second entry will follow location (so we can test the status code to be 200 instead of 301).

```hurl
GET https://google.fr
HTTP 301

GET https://google.fr
[Options]
location: true
HTTP 200

GET https://google.fr
HTTP 301
```

You can use the `[Options](#getting-started-manual-options)` section to log a specific entry:

```hurl
# ... previous entries

GET https://api.example.org
[Options]
very-verbose: true
HTTP 200

# ... next entries
```

#### Cookie storage {#file-format-entry-cookie-storage}

By default, requests in the same Hurl file share cookie storage, enabling session-based scenario. The shared cookie store can
be disabled with [`--no-cookie-store`] option.

#### Redirects {#file-format-entry-redirects}

By default, Hurl doesn't follow redirection. To effectively run a redirection, entries should describe each step
of the redirection, allowing insertion of asserts in each response.

```hurl
# First entry, test the redirection (status code and 'Location' header)
GET https://example.org
HTTP 301
Location: https://www.example.org

# Second entry, the 200 OK response
GET https://www.example.org
HTTP 200
```

Alternatively, one can use [`--location`](#getting-started-manual-location) / [`--location-trusted`](#getting-started-manual-location-trusted) options to force redirection
to be followed. In this case, asserts are executed on the last received response. Optionally, the number of
redirections can be limited with [`--max-redirs`](#getting-started-manual-max-redirs).

```hurl
# Running hurl --location foo.hurl
GET https://example.org
HTTP 200
```

Finally, you can force redirection on a particular request with an [`[Options]` section][options](#file-format-request-options) and the [`--location`](#getting-started-manual-location) 
/ [`--location-trusted`](#getting-started-manual-location-trusted) options:

```hurl
GET https://example.org
[Options]
location-trusted: true
HTTP 200
```

Redirections can be tested either by:

- running and asserting each step of redirection:

```hurl
GET https://example.org/step1
HTTP 301
[Asserts]
header "Location" == "https://example.org/step2"


GET https://example.org/step2
HTTP 301
[Asserts]
header "Location" == "https://example.org/step3"


GET https://example.org/step3
HTTP 200
```

- using [`--location`](#getting-started-manual-location) / [`--location-trusted`](#getting-started-manual-location-trusted), testing each step with [`redirects` query](#file-format-asserting-response-redirects-assert):

```hurl
GET https://example.org/step1
[Options]
location: true
HTTP 200
[Asserts]
redirects count == 2
redirects nth 0 location == "https://example.org/step2"
redirects nth 1 location == "https://example.org/step3"
```

[`url` query](#file-format-asserting-response-url-assert) can also be used to get the final effective URL:

```hurl
GET https://example.org/step1
[Options]
location: true
HTTP 200
[Asserts]
url == "https://example.org/step3"
```

#### Retry {#file-format-entry-retry}

Every entry can be retried upon asserts, captures or runtime errors. Retries allow polling scenarios and effective runs 
under flaky conditions. Asserts can be explicit (with an [`[Asserts]` section][asserts](#file-format-response-asserts)), or implicit (like [headers](#file-format-response-headers) or [status code](#file-format-response-version-status)).

Retries can be set globally for every request (see [`--retry`](#getting-started-manual-retry) and [`--retry-interval`](#getting-started-manual-retry-interval)), 
or activated on a particular request with an [`[Options]` section][options](#file-format-request-options).

For example, in this Hurl file, first we create a new job then we poll the new job until it's completed:

```hurl
# Create a new job
POST http://api.example.org/jobs
HTTP 201
[Captures]
job_id: jsonpath "$.id"
[Asserts]
jsonpath "$.state" == "RUNNING"


# Pull job status until it is completed
GET http://api.example.org/jobs/{{job_id}}
[Options]
retry: 10   # maximum number of retry, -1 for unlimited
retry-interval: 300ms
HTTP 200
[Asserts]
jsonpath "$.state" == "COMPLETED"
```

#### Control flow {#file-format-entry-control-flow}

In `[Options](#getting-started-manual-options)` section, `skip` and `repeat` can be used to control flow of execution:

- `skip: true/false` skip this request and execute the next one unconditionally,
- `repeat: N` loop the request N times. If there are assert or runtime errors, the requests execution is stopped.

```hurl
# This request will be played exactly 3 times
GET https://example.org/foo
[Options]
repeat: 3
HTTP 200

# This request is skipped
GET https://example.org/foo
[Options]
skip: true
HTTP 200
```

Additionally, a `delay` can be inserted between requests, to add a delay before execution of a request (aka sleep).

```hurl
# A 5 seconds delayed request 
GET https://example.org/foo
[Options]
delay: 5s
HTTP 200
```

[`delay`](#getting-started-manual-retry) and [`repeat`](#getting-started-manual-repeat) can also be used globally as command line options:

```shell
$ hurl --delay 500ms --repeat 3 foo.hurl
```



For complete reference, below is a diagram for the executed entries.

## Request {#file-format-request-request}

### Definition {#file-format-request-definition}

Request describes an HTTP request: a mandatory [method](#file-format-request-method) and [URL](#file-format-request-url), followed by optional [headers](#file-format-request-headers).

Then, [options](#file-format-request-options), [query parameters](#file-format-request-query-parameters), [form parameters](#file-format-request-form-parameters), [multipart form data](#file-format-request-multipart-form-data), [cookies](#file-format-request-cookies), and [basic authentication](#file-format-request-basic-authentication)
can be used to configure the HTTP request.

Finally, an optional [body](#file-format-request-body) can be used to configure the HTTP request body.

### Example {#file-format-request-example}

```hurl
GET https://example.org/api/dogs?id=4567
User-Agent: My User Agent
Content-Type: application/json
[BasicAuth]
alice: secret

[Headers](#file-format-request-headers), if present, follow directly after the [method](#file-format-request-method) and [URL](#file-format-request-url). This allows Hurl format to 'look like' the real HTTP format.
Contrary to HTTP headers, other parameters are defined in sections (`[Cookies]`, `[Query]`, `[Form]` etc...)
These sections are not ordered and can be mixed in any way:

```hurl
GET https://example.org/api/dogs
User-Agent: My User Agent
[Query]
id: 4567
order: newest
[BasicAuth]
alice: secret
```

```hurl
GET https://example.org/api/dogs
User-Agent: My User Agent
[BasicAuth]
alice: secret
[Query]
id: 4567
order: newest
```

The last optional part of a request configuration is the request [body](#file-format-request-body). Request body must be the last parameter of a request
(after [headers](#file-format-request-headers) and request sections). Like headers, body have no explicit marker:

```hurl
POST https://example.org/api/dogs?id=4567
User-Agent: My User Agent
{
 "name": "Ralphy"
}
```

### Description {#file-format-request-description}

#### Method {#file-format-request-method}

Mandatory HTTP request method, usually one of `GET`, `HEAD`, `POST`, `PUT`, `DELETE`, `CONNECT`, `OPTIONS`,
`TRACE` and `PATCH`. 

> Other methods can be used like `QUERY` with the constraint of using only uppercase chars.

#### URL {#file-format-request-url}

Mandatory HTTP request URL.

URL can contain query parameters, even if using a [query parameters section](#file-format-request-query-parameters) is preferred.

```hurl
# A request with URL containing query parameters.
GET https://example.org/forum/questions/?search=Install%20Linux&order=newest

# A request with query parameters section, equivalent to the first request.
GET https://example.org/forum/questions/
[Query]
search: Install Linux
order: newest
```

> Query parameters in query parameter section are not URL encoded.

When query parameters are present in the URL and in a query parameters section, the resulting request will
have both parameters.

#### Headers {#file-format-request-headers}

Optional list of HTTP request headers.

A header consists of a name, followed by a `:` and a value.

```hurl
GET https://example.org/news
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:70.0) Gecko/20100101 Firefox/70.0
Accept: */*
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
```

> Headers directly follow URL, without any section name, contrary to query parameters, form parameters
> or cookies

Note that a header usually doesn't start with double quotes. If a header value starts with double quotes, double
quotes will be part of the header value:

```hurl
PATCH https://example.org/file.txt
If-Match: "e0023aa4e"
```

`If-Match` request header will be sent will the following value `"e0023aa4e"` (started and ended with double quotes).

Headers must follow directly after the [method](#file-format-request-method) and [URL](#file-format-request-url).

#### Options {#file-format-request-options}

Options used to execute this request.

Options such as [`--location`](#getting-started-manual-location), [`--verbose`](#getting-started-manual-verbose), [`--insecure`](#getting-started-manual-insecure) can be used at the command line and applied to every
request of an Hurl file. An `[Options]` section can be used to apply option to only one request (without passing options
to the command line), while other requests are unaffected.

```hurl
GET https://example.org
# An options section, each option is optional and applied only to this request...
[Options]
aws-sigv4: aws:amz:sts     # generate AWS SigV4 Authorization header
cacert: /etc/cert.pem      # custom certificate file
cert: /etc/client-cert.pem # client authentication certificate
key: /etc/client-cert.key  # client authentication certificate key
compressed: true           # request a compressed response
connect-timeout: 20s       # connect timeout
delay: 3s                  # delay for this request (aka sleep)
http3: true                # use HTTP/3 protocol version
insecure: true             # allow insecure SSL connections and transfers
ipv6: true                 # use IPv6 addresses
limit-rate: 32000          # limit this request to the specidied speed (bytes/s)
location: true             # follow redirection for this request
max-redirs: 10             # maximum number of redirections
max-time: 30s              # maximum time for a request/response
output: out.html           # dump the response to this file
path-as-is: true           # do not handle sequences of /../ or /./ in URL path
retry: 10                  # number of retry if HTTP/asserts errors
retry-interval: 500ms      # interval between retry
skip: false                # skip this request
unix-socket: sock          # use Unix socket for transfer
user: bob:secret           # use basic authentication
proxy: my.proxy:8012       # define proxy (host:port where host can be an IP address)
variable: country=Italy    # define variable country
variable: planet=Earth     # define variable planet
verbose: true              # allow verbose output
very-verbose: true         # allow more verbose output    
```

> Variable defined in an `[Options]` section are defined also for the next entries. This is
> the exception, all other options are defined only for the current request.

#### Query parameters {#file-format-request-query-parameters}

Optional list of query parameters.

A query parameter consists of a field, followed by a `:` and a value. The query parameters section starts with
`[Query]`. Contrary to query parameters in the URL, each value in the query parameters section is not
URL encoded.

```hurl
GET https://example.org/news
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:70.0) Gecko/20100101 Firefox/70.0
[Query]
order: newest
search: {{custom-search}}
count: 100
```

If there are any parameters in the URL, the resulted request will have both parameters.

#### Form parameters {#file-format-request-form-parameters}

A form parameters section can be used to send data, like [HTML form](https://developer.mozilla.org/en-US/docs/Learn/Forms).

This section contains an optional list of key values, each key followed by a `:` and a value. Key values will be
encoded in key-value tuple separated by '&', with a '=' between the key and the value, and sent in the body request.
The content type of the request is `application/x-www-form-urlencoded`. The form parameters section starts
with `[Form]`.

```hurl
POST https://example.org/contact
[Form]
default: false
token: {{token}}
email: john.doe@rookie.org
number: 33611223344
```

Form parameters section can be seen as syntactic sugar over body section (values in form parameters section
are not URL encoded.). A [oneline string body](#file-format-request-oneline-string-body) could be used instead of a forms parameters section.

~~~hurl
# Run a POST request with form parameters section:
POST https://example.org/test
[Form]
name: John Doe
key1: value1

# Run the same POST request with a body section:
POST https://example.org/test
Content-Type: application/x-www-form-urlencoded
`name=John%20Doe&key1=value1`
~~~

When both [body section](#file-format-request-body) and form parameters section are present, only the body section is taken into account.

#### Multipart Form Data {#file-format-request-multipart-form-data}

A multipart form data section can be used to send data, with key / value and file content
(see [multipart/form-data on MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST)).

The form parameters section starts with `[Multipart]`.

```hurl
POST https://example.org/upload
[Multipart]
field1: value1
field2: file,example.txt;
# One can specify the file content type:
field3: file,example.zip; application/zip
```

Files are relative to the input Hurl file, and cannot contain implicit parent directory (`..`). You can use  
[`--file-root` option](#getting-started-manual-file-root) to specify the root directory of all file nodes.

Content type can be specified or inferred based on the filename extension:

- `.gif`: `image/gif`,
- `.jpg`: `image/jpeg`,
- `.jpeg`: `image/jpeg`,
- `.png`: `image/png`,
- `.svg`: `image/svg+xml`,
- `.txt`: `text/plain`,
- `.htm`: `text/html`,
- `.html`: `text/html`,
- `.pdf`: `application/pdf`,
- `.xml`: `application/xml`

By default, content type is `application/octet-stream`.

As an alternative to a `[Multipart]` section, multipart forms can also be sent with a [multiline string body](#file-format-request-multiline-string-body):

~~~hurl
POST https://example.org/upload
Content-Type: multipart/form-data; boundary="boundary"
```
--boundary
Content-Disposition: form-data; name="key1"

value1
--boundary
Content-Disposition: form-data; name="upload1"; filename="data.txt"
Content-Type: text/plain

Hello World!
--boundary
Content-Disposition: form-data; name="upload2"; filename="data.html"
Content-Type: text/html

<div>Hello <b>World</b>!</div>
--boundary--
```
~~~

> When using a multiline string body to send a multipart form data, files content must be inlined in the Hurl file.

#### Cookies {#file-format-request-cookies}

Optional list of session cookies for this request.

A cookie consists of a name, followed by a `:` and a value. Cookies are sent per request, and are not added to
the cookie storage session, contrary to a cookie set in a header response. (for instance `Set-Cookie: theme=light`). The
cookies section starts with `[Cookies]`.

```hurl
GET https://example.org/index.html
[Cookies]
theme: light
sessionToken: abc123
```

Cookies section can be seen as syntactic sugar over corresponding request header.

```hurl
# Run a GET request with cookies section:
GET https://example.org/index.html
[Cookies]
theme: light
sessionToken: abc123

# Run the same GET request with a header:
GET https://example.org/index.html
Cookie: theme=light; sessionToken=abc123
```

#### Basic Authentication {#file-format-request-basic-authentication}

A basic authentication section can be used to perform [basic authentication](#file-format-request-basic-authentication).

Username is followed by a `:` and a password. The basic authentication section starts with
`[BasicAuth]`. Username and password are _not_ base64 encoded.


```hurl
# Perform basic authentication with login `bob` and password `secret`.
GET https://example.org/protected
[BasicAuth]
bob: secret
```

> Spaces surrounded username and password are trimmed. If you
> really want a space in your password (!!), you could use [Hurl unicode literals \u{20}](#file-format-hurl-file-special-characters-in-strings).

This is equivalent (but simpler) to construct the request with a [Authorization](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Authorization) header:

```hurl
# Authorization header value can be computed with `echo -n 'bob:secret' | base64`
GET https://example.org/protected
Authorization: Basic Ym9iOnNlY3JldA== 
```

Basic authentication allows per request authentication.
If you want to add basic authentication to all the requests of a Hurl file
you can use [`-u/--user` option](#getting-started-manual-user).

#### Body {#file-format-request-body}

Optional HTTP body request.

If the body of the request is a [JSON](https://www.json.org) string or a [XML](https://en.wikipedia.org/wiki/XML) string, the value can be
directly inserted without any modification. For a text based body that is neither JSON nor XML,
one can use [multiline string body](#file-format-request-multiline-string-body) that starts with <code>&#96;&#96;&#96;</code> and ends
with <code>&#96;&#96;&#96;</code>. Multiline string body support "language hint" and can be used
to create [GraphQL queries](#file-format-request-graphql-query).

For a precise byte control of the request body, [Base64](https://en.wikipedia.org/wiki/Base64) encoded string, [hexadecimal string](#file-format-request-hex-body)
or [included file](#file-format-request-file-body) can be used to describe exactly the body byte content.

> You can set a body request even with a `GET` body, even if this is not a common practice.

The body section must be the last section of the request configuration.

##### JSON body {#file-format-request-json-body}

JSON request body is used to set a literal JSON as the request body.

```hurl
# Create a new doggy thing with JSON body:
POST https://example.org/api/dogs
{
    "id": 0,
    "name": "Frieda",
    "picture": "images/scottish-terrier.jpeg",
    "age": 3,
    "breed": "Scottish Terrier",
    "location": "Lisco, Alabama"
}
```

JSON request body can be [templatized with variables](#file-format-templates-templating-body):

```hurl
# Create a new catty thing with JSON body:
POST https://example.org/api/cats
{
    "id": 42,
    "lives": {{ lives_count }},
    "name": "{{ name }}"
}
```


When using JSON request body, the content type `application/json` is automatically set.

JSON request body can be seen as syntactic sugar of [multiline string body](#file-format-request-multiline-string-body) with `json` identifier:

~~~hurl
# Create a new doggy thing with JSON body:
POST https://example.org/api/dogs
```json
{
    "id": 0,
    "name": "Frieda",
    "picture": "images/scottish-terrier.jpeg",
    "age": 3,
    "breed": "Scottish Terrier",
    "location": "Lisco, Alabama"
}
```
~~~

If you don't want templates to be evaluated inside JSON body you can use [multiline string body](#file-format-request-multiline-string-body) with `raw` identifier:

~~~hurl
# {{name}} is not a variable
POST https://example.org/api/cats
Content-Type: application/json
```raw
{
  "id": 42,
  "name": "{{ name }}"
}
```
~~~

##### XML body {#file-format-request-xml-body}

XML request body is used to set a literal XML as the request body.

~~~hurl
# Create a new soapy thing XML body:
POST https://example.org/InStock
Content-Type: application/soap+xml; charset=utf-8
Content-Length: 299
SOAPAction: "http://www.w3.org/2003/05/soap-envelope"
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:m="http://example.net">
  <soap:Header></soap:Header>
  <soap:Body>
    <m:GetStockPrice>
      <m:StockName>GOOG</m:StockName>
    </m:GetStockPrice>
  </soap:Body>
</soap:Envelope>
~~~

XML request body can be seen as syntactic sugar of [multiline string body](#file-format-request-multiline-string-body) with `xml` identifier:

~~~hurl
# Create a new soapy thing XML body:
POST https://example.org/InStock
Content-Type: application/soap+xml; charset=utf-8
Content-Length: 299
SOAPAction: "http://www.w3.org/2003/05/soap-envelope"
```xml
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:m="http://example.net">
  <soap:Header></soap:Header>
  <soap:Body>
    <m:GetStockPrice>
      <m:StockName>GOOG</m:StockName>
    </m:GetStockPrice>
  </soap:Body>
</soap:Envelope>
```
~~~

> Contrary to JSON body, the succinct syntax of XML body can not use variables. If you need to use variables in your
> XML body, use a simple [multiline string body](#file-format-request-multiline-string-body) with variables.

##### GraphQL query {#file-format-request-graphql-query}

GraphQL query uses [multiline string body](#file-format-request-multiline-string-body) with `graphql` identifier:


~~~hurl
POST https://example.org/starwars/graphql
```graphql
{
  human(id: "1000") {
    name
    height(unit: FOOT)
  }
}
```
~~~

GraphQL query body can use [GraphQL variables](https://graphql.org/learn/queries/#variables):

~~~hurl
POST https://example.org/starwars/graphql
```graphql
query Hero($episode: Episode, $withFriends: Boolean!) {
  hero(episode: $episode) {
    name
    friends @include(if: $withFriends) {
      name
    }
  }
}

variables {
  "episode": "JEDI",
  "withFriends": false
}
```
~~~

GraphQL query, as every multiline string body, can use Hurl variables.

~~~hurl
POST https://example.org/starwars/graphql
```graphql
{
  human(id: "{{human_id}}") {
    name
    height(unit: FOOT)
  }
}
```
~~~

> Hurl variables and GraphQL variables can be mixed in the same body.

##### Multiline string body {#file-format-request-multiline-string-body}

For text based body that are neither JSON nor XML, one can use multiline string, started and ending with
<code>&#96;&#96;&#96;</code>.

~~~hurl
POST https://example.org/models
```
Year,Make,Model,Description,Price
1997,Ford,E350,"ac, abs, moon",3000.00
1999,Chevy,"Venture ""Extended Edition""","",4900.00
1999,Chevy,"Venture ""Extended Edition, Very Large""",,5000.00
1996,Jeep,Grand Cherokee,"MUST SELL! air, moon roof, loaded",4799.00
```
~~~

The standard usage of a multiline string is:

~~~
```
line1
line2
line3
```
~~~

is evaluated as "line1\nline2\nline3\n".

Multiline string body can be [templatized with variables](#file-format-templates-templating-body):

~~~hurl
POST https://example.org/models
[Options]
variable: var1=lemon
variable: var2=yellow
```
Fruit,Color
{{var1}},{{var2}}
```
~~~

Escapes are not processed (i.e. [Hurl Unicode literals](#file-format-hurl-file-special-characters-in-strings) are not supported): `\n` is two consecutive
chars (`\` followed by a `n`), not a single newline char.

Multiline string body can use language identifier, like `json`, `xml`, `graphql` or `raw`. Depending on the language identifier,
an additional 'Content-Type' request header is sent, and the real body (bytes sent over the wire) can be different from the 
raw multiline text.

~~~hurl
POST https://example.org/api/dogs
```json
{
    "id": 0,
    "name": "Frieda"
}
```
~~~

Raw multiline string body don't evaluate templates:

~~~hurl
# {{name}} is not a variable
POST https://example.org/api/cats
Content-Type: application/json
```raw
{
    "id": 42,
    "lives": {{ lives_count }},
    "name": "{{ name }}"
}
```
~~~

##### Oneline string body {#file-format-request-oneline-string-body}

For text based body that do not contain newlines, one can use oneline string, started and ending with <code>&#96;</code>.

~~~hurl
POST https://example.org/helloworld
`Hello world!`
~~~

##### Base64 body {#file-format-request-base64-body}

Base64 body is used to set binary data as the request body.

Base64 body starts with `base64,` and end with `;`. MIME's Base64 encoding is supported (newlines and white spaces may be
present anywhere but are to be ignored on decoding), and `=` padding characters might be added.

```hurl
POST https://example.org
# Some random comments before body
base64,TG9yZW0gaXBzdW0gZG9sb3Igc2l0IGFtZXQsIGNvbnNlY3RldHVyIG
FkaXBpc2NpbmcgZWxpdC4gSW4gbWFsZXN1YWRhLCBuaXNsIHZlbCBkaWN0dW0g
aGVuZHJlcml0LCBlc3QganVzdG8gYmliZW5kdW0gbWV0dXMsIG5lYyBydXRydW
0gdG9ydG9yIG1hc3NhIGlkIG1ldHVzLiA=;
```

##### Hex body {#file-format-request-hex-body}

Hex body is used to set binary data as the request body.

Hex body starts with `hex,` and end with `;`.

```hurl
PUT https://example.org
# Send a café, encoded in UTF-8
hex,636166c3a90a;
```

##### File body {#file-format-request-file-body}

To use the binary content of a local file as the body request, file body can be used. File body starts with
`file,` and ends with `;``

```hurl
POST https://example.org
# Some random comments before body
file,data.bin;
```

File are relative to the input Hurl file, and cannot contain implicit parent directory (`..`). You can use  
[`--file-root` option](#getting-started-manual-file-root) to specify the root directory of all file nodes.



<hr>

## Response {#file-format-response-response}

### Definition {#file-format-response-definition}

Responses can be used to capture values to perform subsequent requests, or add asserts to HTTP responses. Response on
requests are optional, a Hurl file can just consist of a sequence of [requests](#file-format-request).

A response describes the expected HTTP response, with mandatory [version and status](#file-format-asserting-response-version-status), followed by optional [headers](#file-format-asserting-response-headers),
[captures](#file-format-capturing-response-captures), [asserts](#file-format-asserting-response-asserts) and [body](#file-format-asserting-response-body). Assertions in the expected HTTP response describe values of the received HTTP response.
Captures capture values from the received HTTP response and populate a set of named variables that can be used
in the following entries.

### Example {#file-format-response-example}

```hurl
GET https://example.org
HTTP 200
Last-Modified: Wed, 21 Oct 2015 07:28:00 GMT
[Asserts]
xpath "normalize-space(//head/title)" startsWith "Welcome"
xpath "//li" count == 18
```

### Capture and Assertion {#file-format-response-capture-and-assertion}

With the response section, one can optionally [capture value from headers, body](#file-format-capturing-response), or [add assert on status code, body or headers](#file-format-asserting-response).

#### Body compression {#file-format-response-body-compression}

Hurl outputs the raw HTTP body to stdout by default. If response body is compressed (using [br, gzip, deflate](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Encoding)),
the binary stream is output, without any modification. One can use [`--compressed` option](#getting-started-manual-compressed)
to request a compressed response and automatically get the decompressed body.

Captures and asserts work automatically on the decompressed body, so you can request compressed data (using [`Accept-Encoding`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Encoding)
header by example) and add assert and captures on the decoded body as if there weren't any compression.

### Timings {#file-format-response-timings}

HTTP response timings are exposed through Hurl structured output (see [`--json`](#getting-started-manual-json)), HTML report (see [`--report-html`](#getting-started-manual-report-html))
and JSON report (see [`--report-json`](#getting-started-manual-report-json)).

On each response, libcurl response timings are available:

- __time_namelookup__: the time it took from the start until the name resolving was completed. You can use
  [`--resolve`](#getting-started-manual-resolve) to exclude DNS performance from the measure.
- __time_connect__:  The time it took from the start until the TCP connect to the remote host (or proxy) was completed.
- __time_appconnect__: The time it took from the start until the SSL/SSH/etc connect/handshake to the remote host was
  completed. The client is then ready to send its HTTP GET request.
- __time_starttransfer__: The time it took from the start until the first byte was just about to be transferred
  (just before Hurl reads the first byte from the network). This includes time_pretransfer and also the time the server
  needed to calculate the result.
- __time_total__: The total time that the full operation lasted.

All timings are in microsecond.

## Capturing Response {#file-format-capturing-response-capturing-response}

### Captures {#file-format-capturing-response-captures}

Captures are optional values that are __extracted from the HTTP response__ and stored in a named variable.
These captures may be the response status code, part of or the entire the body, and response headers.

Captured variables can be accessed through a run session; each new value of a given variable overrides the last value.

Captures can be useful for using data from one request in another request, such as when working with [CSRF tokens](https://en.wikipedia.org/wiki/Cross-site_request_forgery).
Variables in a Hurl file can be created from captures or [injected into the session](#file-format-templates-injecting-variables).

```hurl
# An example to show how to pass a CSRF token
# from one request to another:

# First GET request to get CSRF token value:
GET https://example.org
HTTP 200
# Capture the CSRF token value from html body.
[Captures]
csrf_token: xpath "normalize-space(//meta[@name='_csrf_token']/@content)"

# Do the login !
POST https://acmecorp.net/login?user=toto&password=1234
X-CSRF-TOKEN: {{csrf_token}}
HTTP 302
```

Body responses can be encoded by server (see [`Content-Encoding` HTTP header]) but captures in Hurl files are not
affected by this content compression. All body captures (`body`, `bytes`, `sha256` etc...) except `rawbytes` work _after_ content decoding.

Finally, body text captures (`body`, `jsonpath`, `xpath` etc...) are also decoded to strings based on [`Content-Type` header]
so these queries can be captures as usual strings.


Structure of a capture:

<div class="schema-container schema-container u-font-size-2 u-font-size-3-sm">
 <div class="schema">
   <span class="schema-token schema-color-1">my_var<span class="schema-label">variable</span></span>
   <span> : </span>
   <span class="schema-token schema-color-2">xpath "string(//h1)"<span class="schema-label">query</span></span>
 </div>
</div>

A capture consists of a variable name, followed by `:` and a query. Captures
section starts with `[Captures]`.

#### Query {#file-format-capturing-response-query}

Queries are used to extract data from an HTTP response.

A query can extract data from

- status line:
  - [`status`](#file-format-capturing-response-status-capture)
  - [`version`](#file-format-capturing-response-version-capture)
- headers:
  - [`header`](#file-format-capturing-response-header-capture)
  - [`cookie`](#file-format-capturing-response-cookie-capture)
- body:
  - [`body`](#file-format-capturing-response-body-capture)
  - [`bytes`](#file-format-capturing-response-bytes-capture)
  - [`xpath`](#file-format-capturing-response-xpath-capture)
  - [`jsonpath`](#file-format-capturing-response-jsonpath-capture)
  - [`regex`](#file-format-capturing-response-regex-capture)
  - [`sha256`](#file-format-capturing-response-sha-256-capture)
  - [`md5`](#file-format-capturing-response-md5-capture)
- others:
  - [`url`](#file-format-capturing-response-url-capture)
  - [`redirects`](#file-format-capturing-response-redirects-capture)
  - [`ip`](#file-format-capturing-response-ip-address-capture)
  - [`variable`](#file-format-capturing-response-variable-capture)
  - [`duration`](#file-format-capturing-response-duration-capture)
  - [`certificate`](#file-format-capturing-response-ssl-certificate-capture)

Extracted data can then be further refined using [filters](#file-format-filters).

#### Status capture {#file-format-capturing-response-status-capture}

Capture the received HTTP response status code. Status capture consists of a variable name, followed by a `:`, and the
keyword `status`.

```hurl
GET https://example.org
HTTP 200
[Captures]
my_status: status
```

#### Version capture {#file-format-capturing-response-version-capture}

Capture the received HTTP version. Version capture consists of a variable name, followed by a `:`, and the
keyword `version`. The value captured is a string:

```hurl
GET https://example.org
HTTP 200
[Captures]
http_version: version
```

#### Header capture {#file-format-capturing-response-header-capture}

Capture a header from the received HTTP response headers. Header capture consists of a variable name, followed by a `:`,
then the keyword `header` and a header name.

```hurl
POST https://example.org/login
[Form]
user: toto
password: 12345678
HTTP 302
[Captures]
next_url: header "Location"
```

#### Cookie capture {#file-format-capturing-response-cookie-capture}

Capture a [`Set-Cookie`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie) header from the received HTTP response headers. Cookie
capture consists of a variable name, followed by a `:`, then the keyword `cookie`
and a cookie name.

```hurl
GET https://example.org/cookies/set
HTTP 200
[Captures]
session-id: cookie "LSID"
```

Cookie attributes value can also be captured by using the following format:
`<cookie-name>[cookie-attribute]`. The following attributes are supported:
`Value`, `Expires`, `Max-Age`, `Domain`, `Path`, `Secure`, `HttpOnly` and `SameSite`.

```hurl
GET https://example.org/cookies/set
HTTP 200
[Captures]
value1: cookie "LSID"
value2: cookie "LSID[Value]"     # Equivalent to the previous capture
expires: cookie "LSID[Expires]"
max-age: cookie "LSID[Max-Age]"
domain: cookie "LSID[Domain]"
path: cookie "LSID[Path]"
secure: cookie "LSID[Secure]"
http-only: cookie "LSID[HttpOnly]"
same-site: cookie "LSID[SameSite]"
```

#### Body capture {#file-format-capturing-response-body-capture}

Capture the entire body (decoded as text) from the received HTTP response. The encoding used to decode the body 
is based on the `charset` value in the `Content-Type` header response.

```hurl
GET https://example.org/home
HTTP 200
[Captures]
my_body: body
```

If the `Content-Type` doesn't include any encoding hint, a [`decode` filter](#file-format-filters-decode) can be used to explicitly decode the body response
bytes.

```hurl
# Our HTML response is encoded using GB 2312.
# But, the 'Content-Type' HTTP response header doesn't precise any charset,
# so we decode explicitly the bytes.
GET https://example.org/cn
HTTP 200
[Captures]
my_body: bytes decode "gb2312"
```

`body` capture works _after_ content encoding decompression (so the captured value is not affected by `Content-Encoding` response header).

#### Bytes capture {#file-format-capturing-response-bytes-capture}

Capture the entire body (as a raw bytestream) from the received HTTP response

```hurl
GET https://example.org/data.bin
HTTP 200
[Captures]
my_data: bytes
```

Like `body` capture, `bytes` capture works _after_ content encoding decompression (so the captured value is not
affected by `Content-Encoding` response header).

#### RawBytes capture {#file-format-capturing-response-rawbytes-capture}

Capture the entire body as a raw bytestream from the received HTTP response, _before_ any content decoding.

```hurl
GET https://example.org/data.bin
HTTP 200
[Captures]
raw_data: rawbytes
```

Unlike `bytes` capture, `rawbytes` returns the raw bytes before content encoding decompression. For uncompressed responses, `rawbytes` and `bytes` capture the same data.

#### XPath capture {#file-format-capturing-response-xpath-capture}

Capture a [XPath](https://en.wikipedia.org/wiki/XPath) query from the received HTTP body decoded as a string.
Currently, only XPath 1.0 expression can be used.

```hurl
GET https://example.org/home
# Capture the identifier from the dom node <div id="pet0">5646eaf23</div
HTTP 200
[Captures]
pet-id: xpath "normalize-space(//div[@id='pet0'])"

# Open the captured page.
GET https://example.org/home/pets/{{pet-id}}
HTTP 200
```

XPath captures are not limited to node values (like string, or boolean); any
valid XPath can be captured and asserted with variable asserts.

```hurl
# Test that the XML endpoint return 200 pets
GET https://example.org/api/pets
HTTP 200
[Captures]
pets: xpath "//pets"
[Asserts]
variable "pets" count == 200
```

XPath expression can also be evaluated against part of the body with a [`xpath` filter](#file-format-filters-xpath):

```hurl
GET https://example.org/home_cn
HTTP 200
[Captures]
pet-id: bytes decode "gb2312" xpath "normalize-space(//div[@id='pet0'])"
```

#### JSONPath capture {#file-format-capturing-response-jsonpath-capture}

Capture a [JSONPath](https://goessner.net/articles/JsonPath/) query from the received HTTP body.

```hurl
POST https://example.org/api/contact
[Form]
token: {{token}}
email: toto@rookie.net
HTTP 200
[Captures]
contact-id: jsonpath "$['id']"
```

> Explain that the value selected by the JSONPath is coerced to a string when only one node is selected.

As with [XPath captures](#file-format-capturing-response-xpath-capture), JSONPath captures can be anything from string, number, to object and collections.
For instance, if we have a JSON endpoint that returns the following JSON:

```
{
  "a_null": null,
  "an_object": {
    "id": "123"
  },
  "a_list": [
    1,
    2,
    3
  ],
  "an_integer": 1,
  "a float": 1.1,
  "a_bool": true,
  "a_string": "hello"
}
```

We can capture the following paths:

```hurl
GET https://example.org/captures-json
HTTP 200
[Captures]
an_object:  jsonpath "$['an_object']"
a_list:     jsonpath "$['a_list']"
a_null:     jsonpath "$['a_null']"
an_integer: jsonpath "$['an_integer']"
a_float:    jsonpath "$['a_float']"
a_bool:     jsonpath "$['a_bool']"
a_string:   jsonpath "$['a_string']"
all:        jsonpath "$"
```

#### Regex capture {#file-format-capturing-response-regex-capture}

Capture a regex pattern from the HTTP received body, decoded as text.

```hurl
GET https://example.org/helloworld
HTTP 200
[Captures]
id_a: regex "id_a:([0-9]+)"
id_b: regex "id_b:(\\d+)"   # pattern using double quote 
id_c: regex /id_c:(\d+)/    # pattern using forward slash
name: regex "Hello ([a-zA-Z]+)"
```

The regex pattern must have at least one capture group, otherwise the
capture will fail. When the pattern is a double-quoted string, metacharacters beginning with a backslash in the pattern
(like `\d`, `\s`) must be escaped; literal pattern enclosed by `/` can also be used to avoid metacharacters escaping.

The regex syntax is documented at <https://docs.rs/regex/latest/regex/#syntax>. For instance, one can use [flags](https://docs.rs/regex/latest/regex/#grouping-and-flags)
to enable case-insensitive match:

```hurl
GET https://example.org/hello
HTTP 200
[Captures]
word: regex /(?i)hello (\w+)!/
```

#### SHA-256 capture {#file-format-capturing-response-sha-256-capture}

Capture the [SHA-256](https://en.wikipedia.org/wiki/SHA-2) hash of the response body.

```hurl
GET https://example.org/data.tar.gz
HTTP 200
[Captures]
my_hash: sha256
```

Like `body` assert, `sha256` capture works _after_ content encoding decompression (so the captured value is not
affected by `Content-Encoding` response header).

#### MD5 capture {#file-format-capturing-response-md5-capture}

Capture the [MD5](https://en.wikipedia.org/wiki/MD5) hash of the response body.

```hurl
GET https://example.org/data.tar.gz
HTTP 200
[Captures]
my_hash: md5
```

Like `sha256` asserts, `md5` assert works _after_ content encoding decompression (so the predicates values are not
affected by `Content-Encoding` response header)

#### URL capture {#file-format-capturing-response-url-capture}

Capture the last fetched URL. This is most meaningful if you have told Hurl to follow redirection (see [`[Options]` section][options](#file-format-request-options) or
[`--location` option](#getting-started-manual-location)). URL capture consists of a variable name, followed by a `:`, and the keyword `url`.

```hurl
GET https://example.org/redirecting
[Options]
location: true
HTTP 200
[Captures]
landing_url: url
```

#### Redirects capture {#file-format-capturing-response-redirects-capture}

Capture each step of redirection. This is most meaningful if you have told Hurl to follow redirection (see [`[Options]`section][options](#file-format-request-options) or
[`--location` option](#getting-started-manual-location)). Redirects capture consists of a variable name, followed by a `:`, and the keyword `redirects`.
Redirects query returns a collection so each step of the redirection can be capture.

```hurl
GET https://example.org/redirecting/1
[Options]
location: true
HTTP 200
[Asserts]
redirects count == 3
[Captures]
step1: redirects nth 0 location
step2: redirects nth 1 location
step3: redirects nth 2 location
```

#### IP address capture {#file-format-capturing-response-ip-address-capture}

Capture the IP address of the last connection. The value of the `ip` query is a string.

```hurl
GET https://example.org/hello
HTTP 200
[Captures]
server_ip: ip
```

#### Variable capture {#file-format-capturing-response-variable-capture}

Capture the value of a variable into another.

```hurl
GET https://example.org/helloworld
HTTP 200
[Captures]
in: body
name: variable "in"
```

#### Duration capture {#file-format-capturing-response-duration-capture}

Capture the response time of the request in ms.

```hurl
GET https://example.org/helloworld
HTTP 200
[Captures]
duration_in_ms: duration
```

#### SSL certificate capture {#file-format-capturing-response-ssl-certificate-capture}

Capture the SSL certificate properties. Certificate capture consists of the keyword `certificate`, followed by the certificate attribute value.

The following attributes are supported: `Subject`, `Issuer`, `Start-Date`, `Expire-Date` and `Serial-Number`.

```hurl
GET https://example.org
HTTP 200
[Captures]
cert_subject: certificate "Subject"
cert_issuer: certificate "Issuer"
cert_expire_date: certificate "Expire-Date"
cert_serial_number: certificate "Serial-Number"
```

### Redacting Secrets {#file-format-capturing-response-redacting-secrets}

When capturing data, you may need to hide captured values from logs and report. To do this, captures can use secrets
which are redacted from logs and reports, using [`--secret` option](#file-format-templates-secrets):

```shell
$ hurl --secret pass=sesame-ouvre-toi file.hurl
```

If the secret value to be redacted is dynamic, or not known before execution, a capture can become a secret using `redact`
at the end of the query's capture:

```hurl
GET https://foo.com
HTTP 200
[Captures]
pass: header "token" redact
```



<hr>

## Asserting Response {#file-format-asserting-response-asserting-response}

### Asserts {#file-format-asserting-response-asserts}

Asserts are used to test various properties of an HTTP response. Asserts can be implicits (such as version, status, 
headers) or explicit within an `[Asserts]` section. The delimiter of the request / response is `HTTP <STATUS-CODE>`: 
after this delimiter, you'll find the implicit asserts, then an `[Asserts]` section with all the explicit checks.

```hurl
GET https://example.org/api/cats
HTTP 200
# Implicit assert on `Content-Type` Header
Content-Type: application/json; charset=utf-8 
[Asserts]
# Explicit asserts section 
bytes count == 120
header "Content-Type" contains "utf-8"
jsonpath "$.cats" count == 49
jsonpath "$.cats[0].name" == "Felix"
jsonpath "$.cats[0].lives" == 9
```

Body responses can be encoded by server (see [`Content-Encoding` HTTP header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Encoding)) but asserts in Hurl files are not 
affected by this content compression. All body asserts (`body`, `bytes`, `sha256` etc...) except `rawbytes` work _after_ content decoding.

Finally, body text asserts (`body`, `jsonpath`, `xpath` etc...) are also decoded to strings based on [`Content-Type` header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Type) 
so these asserts can be written with usual strings. 

#### Structure {#file-format-asserting-response-structure}

The asserts order in a Hurl file is:

- [implicit asserts on version and status](#file-format-asserting-response-version-status)
- [implicit asserts on headers](#file-format-asserting-response-headers)
- [explicit asserts](#file-format-asserting-response-explicit-asserts)
- [implicit assert on body](#file-format-asserting-response-body)

</div>
</div>

### Implicit asserts {#file-format-asserting-response-implicit-asserts}

#### Version - Status {#file-format-asserting-response-version-status}

Expected protocol version and status code of the HTTP response.

Protocol version is one of `HTTP/1.0`, `HTTP/1.1`, `HTTP/2`, `HTTP/3` or
`HTTP`; `HTTP` describes any version. Note that there are no status text following the status code.

```hurl
GET https://example.org/404.html
HTTP 404
```

Wildcard keywords `HTTP` and `*` can be used to disable tests on protocol version and status:

```hurl
GET https://example.org/api/pets
HTTP *
# Check that response status code is > 400 and <= 500
[Asserts]
status > 400
status <= 500
```

While `HTTP/1.0`, `HTTP/1.1`, `HTTP/2` and `HTTP/3` explicitly check HTTP version:

```hurl
# Check that our server responds with HTTP/2
GET https://example.org/api/pets
HTTP/2 200 
```

#### Headers {#file-format-asserting-response-headers}

Optional list of the expected HTTP response headers that must be in the received response.

A header consists of a name, followed by a `:` and a value.

For each expected header, the received response headers are checked. If the received header is not equal to the 
expected, or not present, an error is raised. The comparison is case-insensitive for the name: expecting a 
`Content-Type` header is equivalent to a `content-type` one. Note that the expected headers list is not fully 
descriptive: headers present in the response and not in the expected list doesn't raise error.

```hurl
# Check that user toto is redirected to home after login.
POST https://example.org/login
[Form]
user: toto
password: 12345678
HTTP 302
Location: https://example.org/home
```

> Quotes in the header value are part of the value itself.
>
> This is used by the [ETag](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag) Header
> ```
> ETag: W/"<etag_value>"
> ETag: "<etag_value>"
> ```

Testing duplicated headers is also possible.

For example with the `Set-Cookie` header:

```
Set-Cookie: theme=light
Set-Cookie: sessionToken=abc123; Expires=Wed, 09 Jun 2021 10:18:14 GMT
```

You can either test the two header values:

```hurl
GET https://example.org/index.html
Host: example.net
HTTP 200
Set-Cookie: theme=light
Set-Cookie: sessionToken=abc123; Expires=Wed, 09 Jun 2021 10:18:14 GMT
```

Or only one:

```hurl
GET https://example.org/index.html 
Host: example.net
HTTP 200
Set-Cookie: theme=light
```

If you want to test specifically the number of headers returned for a given header name, or if you want to test header 
value with [predicates](#file-format-asserting-response-predicates) (like `startsWith`, `contains`, `exists`)you can use the explicit [header assert](#file-format-asserting-response-header-assert).

#### Body {#file-format-asserting-response-body}

Optional assertion on the received HTTP response body. Body section can be seen as syntactic sugar over [body asserts](#file-format-asserting-response-body-assert)
(with `==` predicate). If the body of the response is a [JSON](https://www.json.org) string or a [XML](https://en.wikipedia.org/wiki/XML) string, the body assertion can be 
directly inserted without any modification. For a text based body that is neither JSON nor XML, one can use multiline
string that starts with <code>&#96;&#96;&#96;</code> and ends with <code>&#96;&#96;&#96;</code>. For a precise byte
control of the response body, a [Base64](https://en.wikipedia.org/wiki/Base64) encoded string or an input file can be used to describe exactly the body byte
content to check.

Like explicit [`body` assert](#file-format-asserting-response-body-assert), the body section is automatically decompressed based on the value of `Content-Encoding`
response header. So, whatever is the response compression (`gzip`, `brotli`, etc...) body section doesn't depend on
the content encoding. For textual body sections (JSON, XML, multiline, etc...), content is also decoded to string, based
on the value of `Content-Type` response header.

##### JSON body {#file-format-asserting-response-json-body}

```hurl
# Get a doggy thing:
GET https://example.org/api/dogs/{{dog-id}}
HTTP 200
{
    "id": 0,
    "name": "Frieda",
    "picture": "images/scottish-terrier.jpeg",
    "age": 3,
    "breed": "Scottish Terrier",
    "location": "Lisco, Alabama"
}
```

JSON response body can be seen as syntactic sugar of [multiline string body](#file-format-asserting-response-multiline-string-body) with `json` identifier:

~~~hurl
# Get a doggy thing:
GET https://example.org/api/dogs/{{dog-id}}
HTTP 200
```json
{
    "id": 0,
    "name": "Frieda",
    "picture": "images/scottish-terrier.jpeg",
    "age": 3,
    "breed": "Scottish Terrier",
    "location": "Lisco, Alabama"
}
```
~~~

##### XML body {#file-format-asserting-response-xml-body}

~~~hurl
GET https://example.org/api/catalog
HTTP 200
<?xml version="1.0" encoding="UTF-8"?>
<catalog>
   <book id="bk101">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications with XML.</description>
   </book>
</catalog>
~~~

XML response body can be seen as syntactic sugar of [multiline string body](#file-format-asserting-response-multiline-string-body) with `xml` identifier:

~~~hurl
GET https://example.org/api/catalog
HTTP 200
```xml
<?xml version="1.0" encoding="UTF-8"?>
<catalog>
   <book id="bk101">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>

      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications with XML.</description>
   </book>
</catalog>
```
~~~

##### Multiline string body {#file-format-asserting-response-multiline-string-body}

~~~hurl
GET https://example.org/models
HTTP 200
```
Year,Make,Model,Description,Price
1997,Ford,E350,"ac, abs, moon",3000.00
1999,Chevy,"Venture ""Extended Edition""","",4900.00
1999,Chevy,"Venture ""Extended Edition, Very Large""",,5000.00
1996,Jeep,Grand Cherokee,"MUST SELL! air, moon roof, loaded",4799.00
```
~~~

The standard usage of a multiline string is :

~~~
```
line1
line2
line3
```
~~~

###### Oneline string body {#file-format-asserting-response-oneline-string-body}

For text based response body that do not contain newlines, one can use oneline string, started and ending with <code>&#96;</code>.

~~~hurl
POST https://example.org/helloworld
HTTP 200
`Hello world!`
~~~

##### Base64 body {#file-format-asserting-response-base64-body}

Base64 response body assert starts with `base64,` and end with `;`. MIME's Base64 encoding is supported (newlines and
white spaces may be present anywhere but are to be ignored on decoding), and `=` padding characters might be added.

```hurl
GET https://example.org
HTTP 200
base64,TG9yZW0gaXBzdW0gZG9sb3Igc2l0IGFtZXQsIGNvbnNlY3RldHVyIG
FkaXBpc2NpbmcgZWxpdC4gSW4gbWFsZXN1YWRhLCBuaXNsIHZlbCBkaWN0dW0g
aGVuZHJlcml0LCBlc3QganVzdG8gYmliZW5kdW0gbWV0dXMsIG5lYyBydXRydW
0gdG9ydG9yIG1hc3NhIGlkIG1ldHVzLiA=;
```

##### File body {#file-format-asserting-response-file-body}

To use the binary content of a local file as the body response assert, file body
can be used. File body starts with `file,` and ends with `;``

```hurl
GET https://example.org
HTTP 200
file,data.bin;
```

File are relative to the input Hurl file, and cannot contain implicit parent directory (`..`). You can use [`--file-root` option](#getting-started-manual-file-root) 
to specify the root directory of all file nodes.

### Explicit asserts {#file-format-asserting-response-explicit-asserts}

Optional list of assertions on the HTTP response within an `[Asserts]` section. Assertions can describe checks
on status code, on the received body (or part of it) and on response headers.

Structure of an assert:

<div class="schema-container schema-container u-font-size-1 u-font-size-2-sm u-font-size-3-md">
 <div class="schema">
   <span class="schema-token schema-color-2">jsonpath "$.book"<span class="schema-label">query</span></span>
   <span class="schema-token schema-color-1">contains<span class="schema-label">predicate type</span></span>
   <span class="schema-token schema-color-3">"Dune"<span class="schema-label">predicate value</span></span>
 </div>
</div>

<div class="schema-container schema-container u-font-size-1 u-font-size-2-sm u-font-size-3-md">
 <div class="schema">
   <span class="schema-token schema-color-2">body<span class="schema-label">query</span></span>
   <span class="schema-token schema-color-1">matches<span class="schema-label">predicate type</span></span>
   <span class="schema-token schema-color-3">/\d{4}-\d{2}-\d{2}/<span class="schema-label">predicate value</span></span>
 </div>
</div>


An assert consists of a query followed by a predicate. The format of the query is shared with [captures](#file-format-capturing-response-query), and queries 
can extract data from

- status line:
  - [`status`](#file-format-asserting-response-status-assert)
  - [`version`](#file-format-asserting-response-version-assert)
- headers:
  - [`header`](#file-format-asserting-response-header-assert)
  - [`cookie`](#file-format-asserting-response-cookie-assert)
- body:
  - [`body`](#file-format-asserting-response-body-assert)
  - [`bytes`](#file-format-asserting-response-bytes-assert)
  - [`xpath`](#file-format-asserting-response-xpath-assert)
  - [`jsonpath`](#file-format-asserting-response-jsonpath-assert)
  - [`regex`](#file-format-asserting-response-regex-assert)
  - [`sha256`](#file-format-asserting-response-sha-256-assert)
  - [`md5`](#file-format-asserting-response-md5-assert)
- others:
  - [`url`](#file-format-asserting-response-url-assert)
  - [`redirects`](#file-format-asserting-response-redirects-assert)
  - [`ip`](#file-format-asserting-response-ip-address-assert)
  - [`variable`](#file-format-asserting-response-variable-assert)
  - [`duration`](#file-format-asserting-response-duration-assert)
  - [`certificate`](#file-format-asserting-response-ssl-certificate-assert)

Queries, in asserts and in captures, can be refined with [filters](#file-format-filters), like [`count`][count](#file-format-filters-count) to add tests on collections
sizes.

#### Predicates {#file-format-asserting-response-predicates}

Predicates consist of a predicate function and a predicate value. Predicate functions are:

| Predicate          | Description                                                                                                                                                                                                                   | Example                                                                                                              |

Each predicate can be negated by prefixing it with `not` (for instance, `not contains` or `not exists`)

<div class="schema-container schema-container u-font-size-1 u-font-size-2-sm u-font-size-3-md">
 <div class="schema">
   <span class="schema-token schema-color-2">jsonpath "$.book"<span class="schema-label">query</span></span>
   <span class="schema-token schema-color-1">not contains<span class="schema-label">predicate type</span></span>
   <span class="schema-token schema-color-3">"Dune"<span class="schema-label">predicate value</span></span>
 </div>
</div>

A predicate value is typed, and can be a string, a boolean, a number, a bytestream, `null` or a collection. Note that
`"true"` is a string, whereas `true` is a boolean.

For instance, to test the presence of a h1 node in an HTML response, the following assert can be used:

```hurl
GET https://example.org/home
HTTP 200
[Asserts]
xpath "boolean(count(//h1))" == true
xpath "//h1" exists # Equivalent but simpler
```

As the XPath query `boolean(count(//h1))` returns a boolean, the predicate value in the assert must be either
`true` or `false` without double quotes. On the other side, say you have an article node and you want to check the value of some
[data attributes](https://developer.mozilla.org/en-US/docs/Learn/HTML/Howto/Use_data_attributes):

```xml
<article
  id="electric-cars"
  data-visible="true"
...
</article>
```

The following assert will check the value of the `data-visible` attribute:

```hurl
GET https://example.org/home
HTTP 200
[Asserts]
xpath "string(//article/@data-visible)" == "true"
```

In this case, the XPath query `string(//article/@data-visible)` returns a string, so the predicate value must be a
string.

The predicate function `==` can be used with string, numbers or booleans; `startWith` and `contains` can only
be used with strings and bytes, while `matches` only works on string. If a query returns a number, using a `matches` 
predicate will cause a runner error.

```hurl
# A really well tested web page...
GET https://example.org/home
HTTP 200
[Asserts]
header "Content-Type" contains "text/html"
header "Last-Modified" == "Wed, 21 Oct 2015 07:28:00 GMT"
xpath "//h1" exists  # Check we've at least one h1
xpath "normalize-space(//h1)" contains "Welcome"
xpath "//h2" count == 13
xpath "string(//article/@data-id)" startsWith "electric"
```

#### Status assert {#file-format-asserting-response-status-assert}

Check the received HTTP response status code. Status assert consists of the keyword `status` followed by a predicate
function and value.

```hurl
GET https://example.org
HTTP *
[Asserts]
status < 300
```

#### Version assert {#file-format-asserting-response-version-assert}

Check the received HTTP version. Version assert consists of the keyword `version` followed by a predicate function
and value. The value returns by `version` is a string:

```hurl
GET https://example.org
HTTP *
[Asserts]
version == "2"
```

#### Header assert {#file-format-asserting-response-header-assert}

Check the value of a received HTTP response header. Header assert consists of the keyword `header` followed by the value
of the header, a predicate function and a predicate value. Like [headers implicit asserts](#file-format-asserting-response-headers), the check is 
case-insensitive for the name: comparing a `Content-Type` header is equivalent to a `content-type` one.

```hurl
GET https://example.org
HTTP 302
[Asserts]
header "Location" contains "www.example.net"
header "Last-Modified" matches /\d{2} [a-z-A-Z]{3} \d{4}/
```

If there are multiple headers with the same name, the header assert returns a collection, so `count`, `contains` can be
used in this case to test the header list.

Let's say we have this request and response:

```
> GET /hello HTTP/1.1
> Host: example.org
> Accept: */*
> User-Agent: hurl/2.0.0-SNAPSHOT
>
* Response: (received 12 bytes in 11 ms)
*
< HTTP/1.0 200 OK
< Vary: Content-Type
< Vary: User-Agent
< Content-Type: text/html; charset=utf-8
< Content-Length: 12
< Server: Flask Server
< Date: Fri, 07 Oct 2022 20:53:35 GMT
```

One can use explicit header asserts:

```hurl
GET https://example.org/hello
HTTP 200
[Asserts]
header "Vary" count == 2
header "Vary" contains "User-Agent"
header "Vary" contains "Content-Type"
```

Or implicit header asserts:

```hurl
GET https://example.org/hello
HTTP 200
Vary: User-Agent
Vary: Content-Type
```

#### Cookie assert {#file-format-asserting-response-cookie-assert}

Check value or attributes of a [`Set-Cookie`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie) response header. Cookie assert consists of the keyword `cookie`, followed 
by the cookie name (and optionally a cookie attribute), a predicate function and value.

Cookie attributes value can be checked by using the following format:`<cookie-name>[cookie-attribute]`. The following 
attributes are supported: `Value`, `Expires`, `Max-Age`, `Domain`, `Path`, `Secure`, `HttpOnly` and `SameSite`.

```hurl
GET http://localhost:8000/cookies/set
HTTP 200

# Explicit check of Set-Cookie header value. If the attributes are
# not in this exact order, this assert will fail. 
Set-Cookie: LSID=DQAAAKEaem_vYg; Expires=Wed, 13 Jan 2021 22:23:01 GMT; Secure; HttpOnly; Path=/accounts; SameSite=Lax;
Set-Cookie: HSID=AYQEVnDKrdst; Domain=localhost; Expires=Wed, 13 Jan 2021 22:23:01 GMT; HttpOnly; Path=/
Set-Cookie: SSID=Ap4PGTEq; Domain=localhost; Expires=Wed, 13 Jan 2021 22:23:01 GMT; Secure; HttpOnly; Path=/

# Using cookie assert, one can check cookie value and various attributes.
[Asserts]
cookie "LSID" == "DQAAAKEaem_vYg"
cookie "LSID[Value]" == "DQAAAKEaem_vYg"
cookie "LSID[Expires]" exists
cookie "LSID[Expires]" contains "Wed, 13 Jan 2021"
cookie "LSID[Max-Age]" not exists
cookie "LSID[Domain]" not exists
cookie "LSID[Path]" == "/accounts"
cookie "LSID[Secure]" exists
cookie "LSID[HttpOnly]" exists
cookie "LSID[SameSite]" == "Lax"
```

> `Secure` and `HttpOnly` attributes can only be tested with `exists` or `not exists` predicates
> to reflect the [Set-Cookie header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie) semantics (in other words, queries `<cookie-name>[HttpOnly]`
> and `<cookie-name>[Secure]` don't return boolean).

#### Body assert {#file-format-asserting-response-body-assert}

Check the value of the received HTTP response body when decoded as a string. Body assert consists of the keyword `body`
followed by a predicate function and value.

```hurl
GET https://example.org
HTTP 200
[Asserts]
body contains "<h1>Welcome!</h1>"
```

The encoding used to decode the response body bytes to a string is based on the `charset` value in the `Content-Type`
header response.

```hurl
# Our HTML response is encoded with GB 2312 (see https://en.wikipedia.org/wiki/GB_2312)
GET https://example.org/cn
HTTP 200
[Asserts]
header "Content-Type" == "text/html; charset=gb2312"
# bytes of the response, without any text decoding:
bytes contains hex,c4e3bac3cac0bde7; # 你好世界 encoded in GB 2312
# text of the response, decoded with GB 2312:
body contains "你好世界"
```

If the `Content-Type` response header doesn't include any encoding hint, a [`decode` filter](#file-format-filters-decode) can be used to explicitly
decode the response body bytes.

```hurl
# Our HTML response is encoded using GB 2312.
# But, the 'Content-Type' HTTP response header doesn't precise any charset,
# so we decode explicitly the bytes.
GET https://example.org/cn
HTTP 200
[Asserts]
header "Content-Type" == "text/html"
bytes contains hex,c4e3bac3cac0bde7; # 你好世界 encoded in GB2312
bytes decode "gb2312" contains "你好世界"
```

Body asserts are automatically decompressed based on the value of `Content-Encoding` response header. So,
whatever is the response compression (`gzip`, `brotli`) etc... asserts values don't depend on the content encoding.

```hurl
# Request a gzipped reponse, the `body` asserts works with ungzipped response
GET https://example.org
Accept-Encoding: gzip
HTTP 200
[Asserts]
header "Content-Encoding" == "gzip"
body contains "<h1>Welcome!</h1>"

# Without content encoding, asserts remains identical
GET https://example.org
HTTP 200
[Asserts]
header "Content-Encoding" not exists
body contains "<h1>Welcome!</h1>"
```

#### Bytes assert {#file-format-asserting-response-bytes-assert}

Check the value of the received HTTP response body as a bytestream. Body assert consists of the keyword `bytes`
followed by a predicate function and value.

```hurl
GET https://example.org/data.bin
HTTP 200
[Asserts]
bytes startsWith hex,efbbbf;
bytes count == 12424
header "Content-Length" == "12424"
```

Like `body` assert, `bytes` assert works _after_ content encoding decompression (so the predicates values are not
affected by `Content-Encoding` response header value).

#### RawBytes assert {#file-format-asserting-response-rawbytes-assert}

Check the value of the received HTTP response body as a raw bytestream. RawBytes assert consists of the keyword `rawbytes`
followed by a predicate function and value.

```hurl
GET https://example.org/data.bin
HTTP 200
Content-Encoding: gzip
[Asserts]
header "Content-Length" == "32"
rawbytes count == 32               # matches Content-Length (compressed size)
bytes count == 100                 # decompressed size is larger
rawbytes startsWith hex,1f8b;      # gzip magic bytes
bytes startsWith hex,48656c6c6f;   # decompressed content starts with "Hello"
```

Unlike `bytes` assert, `rawbytes` returns the raw bytes _before_ any content decoding. For uncompressed responses, `rawbytes` and `bytes` return the same data.

#### XPath assert {#file-format-asserting-response-xpath-assert}

Check the value of a [XPath](https://en.wikipedia.org/wiki/XPath) query on the received HTTP body decoded as a string (using the `charset` value in the
`Content-Type` header response). Currently, only XPath 1.0 expression can be used. Body assert consists of the
keyword `xpath` followed by a predicate function and value. Values can be string,
boolean or number depending on the XPath query.

Let's say we want to check this HTML response:

```plain
$ curl -v https://example.org

< HTTP/1.1 200 OK
< Content-Type: text/html; charset=UTF-8
...
<!doctype html>
<html>
  <head>
    <title>Example Domain</title>
    ...
  </head>

  <body>
    <div>
      <h1>Example</h1>
      <p>This domain is for use in illustrative examples in documents. You may use this domain in literature without prior coordination or asking for permission.</p>
      <p><a href="https://www.iana.org/domains/example">More information...</a></p>
    </div>
  </body>
</html>
```

With Hurl, we can write multiple XPath asserts describing the DOM content:

```hurl
GET https://example.org
HTTP 200
Content-Type: text/html; charset=UTF-8
[Asserts]
xpath "string(/html/head/title)" contains "Example" # Check title
xpath "count(//p)" == 2                             # Check the number of <p>
xpath "//p" count == 2                              # Similar assert for <p>
xpath "boolean(count(//h2))" == false               # Check there is no <h2>  
xpath "//h2" not exists                             # Similar assert for <h2> 
```

XML Namespaces are also supported. Let's say you want to check this XML response:

```xml
<?xml version="1.0"?>
<!-- both namespace prefixes are available throughout -->
<bk:book xmlns:bk='urn:loc.gov:books'
         xmlns:isbn='urn:ISBN:0-395-36341-6'>
    <bk:title>Cheaper by the Dozen</bk:title>
    <isbn:number>1568491379</isbn:number>
</bk:book>
```

This XML response can be tested with the following Hurl file:

```hurl
GET http://localhost:8000/assert-xpath
HTTP 200
[Asserts]

xpath "string(//bk:book/bk:title)" == "Cheaper by the Dozen"
xpath "string(//*[name()='bk:book']/*[name()='bk:title'])" == "Cheaper by the Dozen"
xpath "string(//*[local-name()='book']/*[local-name()='title'])" == "Cheaper by the Dozen"

xpath "string(//bk:book/isbn:number)" == "1568491379"
xpath "string(//*[name()='bk:book']/*[name()='isbn:number'])" == "1568491379"
xpath "string(//*[local-name()='book']/*[local-name()='number'])" == "1568491379"
```

The XPath expressions `string(//bk:book/bk:title)` and `string(//bk:book/isbn:number)` are written with `bk` and `isbn`
namespaces.

> For convenience, the first default namespace can be used with `_`

#### JSONPath assert {#file-format-asserting-response-jsonpath-assert}

Check the value of a [JSONPath](https://goessner.net/articles/JsonPath/) query on the received HTTP body decoded as a JSON document. JSONPath assert consists 
of the keyword `jsonpath` followed by a predicate function and value.

Let's say we want to check this JSON response:

```plain
curl -v http://httpbin.org/json

< HTTP/1.1 200 OK
< Content-Type: application/json
...

{
  "slideshow": {
    "author": "Yours Truly",
    "date": "date of publication",
    "slides": [
      {
        "title": "Wake up to WonderWidgets!",
        "type": "all"
      },
       ...
    ],
    "title": "Sample Slide Show"
  }
}
```

With Hurl, we can write multiple JSONPath asserts describing the DOM content:

```hurl
GET http://httpbin.org/json
HTTP 200
[Asserts]
jsonpath "$.slideshow.author" == "Yours Truly"
jsonpath "$.slideshow.slides[0].title" contains "Wonder"
jsonpath "$.slideshow.slides" count == 2
jsonpath "$.slideshow.date" != null
jsonpath "$.slideshow.slides[*].title" contains "Mind Blowing!"
```

> Explain that the value selected by the JSONPath is coerced to a string when only
> one node is selected.

In `matches` predicates, metacharacters beginning with a backslash (like `\d`, `\s`) must be escaped. Alternatively, 
`matches` predicate support [JavaScript-like Regular expression syntax](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) to enhance the readability:

```hurl
GET https://example.org/hello
HTTP 200
[Asserts]

# Predicate value with matches predicate:
jsonpath "$.date" matches "^\\d{4}-\\d{2}-\\d{2}$"
jsonpath "$.name" matches "Hello [a-zA-Z]+!"

# Equivalent syntax:
jsonpath "$.date" matches /^\d{4}-\d{2}-\d{2}$/
jsonpath "$.name" matches /Hello [a-zA-Z]+!/
```

#### Regex assert {#file-format-asserting-response-regex-assert}

Check that the HTTP received body, decoded as text, matches a regex pattern.

```hurl
GET https://example.org/hello
HTTP 200
[Asserts]
regex "^(\\d{4}-\\d{2}-\\d{2})$" == "2018-12-31"
# Same assert as previous using regex literals
regex /^(\d{4}-\d{2}-\d{2})$/ == "2018-12-31"
```

The regex pattern must have at least one capture group, otherwise the assert will fail. The assertion is done on the 
captured group value. When the regex pattern is a double-quoted string, metacharacters beginning with a backslash in the
pattern (like `\d`, `\s`) must be escaped; literal pattern enclosed by `/` can also be used to avoid metacharacters
escaping.

The regex syntax is documented at <https://docs.rs/regex/latest/regex/#syntax>. For instance, once can use [flags](https://docs.rs/regex/latest/regex/#grouping-and-flags)
to enable case-insensitive match:

```hurl
GET https://example.org/hello
HTTP 200
[Asserts]
regex /(?i)hello (\w+)!/ == "World"
```

#### SHA-256 assert {#file-format-asserting-response-sha-256-assert}

Check response body [SHA-256](https://en.wikipedia.org/wiki/SHA-2) hash.

```hurl
GET https://example.org/data.tar.gz
HTTP 200
[Asserts]
sha256 == hex,039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81;
```

Like `body` assert, `sha256` assert works _after_ content encoding decompression (so the predicates values are not
affected by `Content-Encoding` response header). For instance, if we have a resource `a.txt` on a server with a
given hash `abcdef`, `sha256` value is not affected by `Content-Encoding`:

```hurl
# Without content encoding compression:
GET https://example.org/a.txt
HTTP 200
[Asserts]
sha256 == hex,abcdef;

# With content encoding compression:
GET https://example.org/a.txt
Accept-Encoding: brotli
HTTP 200
[Asserts]
header "Content-Encoding" == "brotli"
sha256 == hex,abcdef;
```

#### MD5 assert {#file-format-asserting-response-md5-assert}

Check response body [MD5](https://en.wikipedia.org/wiki/MD5) hash.

```hurl
GET https://example.org/data.tar.gz
HTTP 200
[Asserts]
md5 == hex,ed076287532e86365e841e92bfc50d8c;
```

Like `sha256` asserts, `md5` assert works _after_ content encoding decompression (so the predicates values are not
affected by `Content-Encoding` response header)

#### URL assert {#file-format-asserting-response-url-assert}

Check the last fetched URL. This is most meaningful if you have told Hurl to follow redirection (see [`[Options]`section][options](#file-format-request-options) or
[`--location` option](#getting-started-manual-location)). URL assert consists of the keyword `url` followed by a predicate function and value.

```hurl
GET https://example.org/redirecting
[Options]
location: true
HTTP 200
[Asserts]
url == "https://example.org/redirected"
```

#### Redirects assert {#file-format-asserting-response-redirects-assert}

Check each step of redirection. This is most meaningful if you have told Hurl to follow redirection (see [`[Options]`section][options](#file-format-request-options) or
[`--location` option](#getting-started-manual-location)). Redirects assert consists of the keyword `redirects` followed by a predicate function and value. The `redirects`
query returns a collection of redirections that can be tested with a [`location` filter](#file-format-filters-location):

```hurl
GET https://example.org/redirecting/1
[Options]
location: true
HTTP 200
[Asserts]
redirects count == 3
redirects nth 0 location == "https://example.org/redirecting/2"
redirects nth 1 location == "https://example.org/redirecting/3"
redirects nth 2 location == "https://example.org/redirected"
```

#### IP address assert {#file-format-asserting-response-ip-address-assert}

Check the IP address of the last connection. The value of the `ip` query is a string.

> Predicates `isIpv4` and `isIpv6` are available to check if a particular string matches an IPv4 or IPv6 address and
> can use with `ip` queries.

```hurl
GET https://example.org/hello
HTTP 200
[Asserts]
ip isIpv4
ip not isIpv6
ip == "172.16.45.87"
```

#### Variable assert {#file-format-asserting-response-variable-assert}

```hurl
# Test that the XML endpoint return 200 pets 
GET https://example.org/api/pets
HTTP 200
[Captures]
pets: xpath "//pets"
[Asserts]
variable "pets" count == 200
```

#### Duration assert {#file-format-asserting-response-duration-assert}

Check the total duration (sending plus receiving time) of the HTTP transaction.

```hurl
GET https://example.org/helloworld
HTTP 200
[Asserts]
duration < 1000   # Check that response time is less than one second
```

#### SSL certificate assert {#file-format-asserting-response-ssl-certificate-assert}

Check the SSL certificate properties. Certificate assert consists of the keyword `certificate`, followed by the 
certificate attribute value.

The following attributes are supported: `Subject`, `Issuer`, `Start-Date`, `Expire-Date`, `Serial-Number`, and `Subject-Alt-Name`.

```hurl
GET https://example.org
HTTP 200
[Asserts]
certificate "Subject" == "CN=example.org"
certificate "Issuer" == "C=US, O=Let's Encrypt, CN=R3"
certificate "Expire-Date" daysAfterNow > 15
certificate "Serial-Number" matches "[0-9af]+"
certificate "Subject-Alt-Name" contains "DNS:example.org"
certificate "Subject-Alt-Name" split "," count == 2
```

## Filters {#file-format-filters-filters}

### Definition {#file-format-filters-definition}

[Captures](#file-format-capturing-response) and [asserts](#file-format-asserting-response) share a common structure: query. A query is used to extract data from an HTTP response; this data 
can come from the HTTP response body, the HTTP response headers or from the HTTP meta-information (like `duration` for instance)...

In this example, the query __`jsonpath "$.books[0].name"`__ is used in a capture to save data and in an assert to test 
the HTTP response body.

__Capture__:

<div class="schema-container schema-container u-font-size-2 u-font-size-3-md">
 <div class="schema">
   <span class="schema-token schema-color-1">name<span class="schema-label">variable</span></span>
   <span> : </span>
   <span class="schema-token schema-color-2">jsonpath "$.books[0].name"<span class="schema-label">query</span></span>
 </div>
</div>

__Assert__:

<div class="schema-container schema-container u-font-size-2 u-font-size-3-md">
 <div class="schema">
   <span class="schema-token schema-color-2">jsonpath "$.books[0].name"<span class="schema-label">query</span></span>
   <span class="schema-token schema-color-3">== "Dune"<span class="schema-label">predicate</span></span>
 </div>
</div>

In both case, the query is exactly the same: queries are the core structure of asserts and captures. Sometimes, you want
to process data extracted by queries: that's the purpose of __filters__.

Filters are used to transform value extracted by a query and can be used in asserts and captures to refine data. Filters 
__can be chained__, allowing for fine-grained data extraction. 


<div class="schema-container schema-container u-font-size-2 u-font-size-3-md">
 <div class="schema">
    <span class="schema-token schema-color-2">jsonpath "$.name"<span class="schema-label">query</span></span>
    <span class="schema-token schema-color-1">split "," nth 0<span class="schema-label">2 filters</span></span>
    <span class="schema-token schema-color-3">== "Herbert"<span class="schema-label">predicate</span></span>
 </div>
</div>


### Example {#file-format-filters-example}

```hurl
GET https://example.org/api
HTTP 200
[Captures]
name: jsonpath "$.user.id" replaceRegex /\d/ "x"
[Asserts]
header "x-servers" split "," count == 2
header "x-servers" split "," nth 0 == "rec1"
header "x-servers" split "," nth 1 == "rec3"
jsonpath "$.books" count == 12
```

```

#### base64UrlSafeDecode {#file-format-filters-base64urlsafedecode}

Decodes a Base64 encoded string into bytes (using [Base64 URL safe encoding](https://datatracker.ietf.org/doc/html/rfc4648#section-5)).

```hurl
GET https://example.org/api
HTTP 200
[Asserts]
jsonpath "$.token" base64UrlSafeDecode == hex,3c3c3f3f3f3e3e;
```

HTTP 200
[Asserts]
bytes base64UrlSafeEncode == "PDw_Pz8-Pg"
```

#### charsetDecode {#file-format-filters-charsetdecode}

Decodes bytes to string using a charset encoding. Encoding labels are defined in [Encoding Standard](https://encoding.spec.whatwg.org/#concept-encoding-get).

```hurl
# The 'Content-Type' HTTP response header does not precise the charset 'gb2312'
# so body must be decoded explicitly by Hurl before processing any text based assert
GET https://example.org/hello_china
HTTP 200
[Asserts]
header "Content-Type" == "text/html"
# Content-Type has no encoding clue, we must decode ourselves the body response.
bytes charsetDecode "gb2312" xpath "string(//body)" == "你好世界"

## Templates {#file-format-templates-templates}

### Variables {#file-format-templates-variables}

In Hurl file, you can generate value using two curly braces, i.e `{{my_variable}}`. For instance, if you want to reuse a
value from an HTTP response in the next entries, you can capture this value in a variable and reuse it in a placeholder.

In this example, we capture the value of a [CSRF token](https://en.wikipedia.org/wiki/Cross-site_request_forgery) from the body of the first response, and inject it
as a header in the next POST request:

```hurl
GET https://example.org
HTTP 200
[Captures]
csrf_token: xpath "string(//meta[@name='_csrf_token']/@content)"

# Do the login !
POST https://acmecorp.net/login?user=toto&password=1234
X-CSRF-TOKEN: {{csrf_token}}
HTTP 302
```

In this second example, we capture the body in a variable `index`, and reuse this value in the query
`jsonpath "$.errors[{{index}}].id"`:


```hurl
GET https://example.org/api/index
HTTP 200
[Captures]
index: body

GET https://example.org/api/status
HTTP 200
[Asserts]
jsonpath "$.errors[{{index}}].id" == "error"
```


### Functions {#file-format-templates-functions}

Besides variables, functions can be used to generate dynamic values. Current functions are:

| Function    | Description                                                    |
|-------------|----------------------------------------------------------------|
| `newUuid`   | Generates an [UUID v4 random string](https://en.wikipedia.org/wiki/Universally_unique_identifier)                           |
| `newDate`   | Generates an [RFC 3339](https://www.rfc-editor.org/rfc/rfc3339) UTC date string, at the current time   |

In the following example, we use `newDate` to generate a dynamic query parameter:

```hurl
GET https://example.org/api/foo
[Query]
date: {{newDate}}
HTTP 200
```

We run a `GET` request to `https://example.org/api/foo?date=2024%2D12%2D02T10%3A35%3A44%2E461731Z` where the `date`
query parameter value is `2024-12-02T10:35:44.461731Z` URL encoded.

In this second example, we use `newUuid` function to generate an email dynamically:

```hurl
POST https://example.org/api/foo
{
  "name": "foo",
  "email": "{{newUuid}}@test.com"
}
```

When run, the request body will be:

```
{
  "name": "foo",
  "email": "0531f78f-7f87-44be-a7f2-969a1c4e6d97@test.com"
}
```


### Types {#file-format-templates-types}

Values generated from function and variables are typed, and can be either string, bool, number, `null` or collections. Depending on the value type,
templates can be rendered differently. Let's say we have captured an integer value into a variable named
`count`:

```hurl
GET https://sample/counter

HTTP 200
[Captures]
count: jsonpath "$.results[0]"
```

The following entry:

```hurl
GET https://sample/counter/{{count}} 

HTTP 200
[Asserts]
jsonpath "$.id" == "{{count}}"
```

will be rendered at runtime to:

```hurl
GET https://sample/counter/458
 
HTTP 200
[Asserts]
jsonpath "$.id" == "458"
```

resulting in a comparison between the [JSONPath](#file-format-asserting-response-jsonpath-assert) expression and a string value.

On the other hand, the following assert:

```hurl
GET https://sample/counter/{{count}} 

HTTP 200
[Asserts]
jsonpath "$.index" == {{count}}
```

will be rendered at runtime to:

```hurl
GET https://sample/counter/458 

HTTP 200
[Asserts]
jsonpath "$.index" == 458
```

resulting in a comparison between the [JSONPath](#file-format-asserting-response-jsonpath-assert) expression and an integer value.

So if you want to use typed values (in asserts for instances), you can use `{{my_var}}`.
If you're interested in the string representation of a variable, you can surround the variable with double quotes
, as in `"{{my_var}}"`.

> When there is no possible ambiguities, like using a variable in an URL, or
> in a header, you can omit the double quotes. The value will always be rendered
> as a string.

### Injecting Variables {#file-format-templates-injecting-variables}

Variables can be injected in a Hurl file:

- by using [`--variable` option](#getting-started-manual-variable)
- by using [`--variables-file` option](#getting-started-manual-variables-file)
- by defining environment variables, for instance `HURL_VARIABLE_foo=bar`
- by defining variables in an [`[Options]` section][options](#file-format-request-options)

Lets' see how to inject variables, given this `test.hurl`:

```hurl
GET https://{{host}}/{{id}}/status
HTTP 304

GET https://{{host}}/health
HTTP 200
```

#### `variable` option {#file-format-templates-variable-option}

Variable can be defined with command line option:

```shell
$ hurl --variable host=example.net --variable id=1234 test.hurl
``` 


#### `variables-file` option {#file-format-templates-variables-file-option}

We can also define all injected variables in a file:

```shell
$ hurl --variables-file vars.env test.hurl
``` 

where `vars.env` is

```
host=example.net
id=1234
```

#### Environment variable {#file-format-templates-environment-variable}

We can use environment variables in the form of `HURL_VARIABLE_name=value`:

```shell
$ export HURL_VARIABLE_host=example.net
$ export HURL_VARIABLE_id=1234 
$ hurl test.hurl
```

#### Options sections {#file-format-templates-options-sections}

We can define variables in `[Options]` section. Variables defined in a section are available for the next requests.

```hurl
GET https://{{host}}/{{id}}/status
[Options]
variable: host=example.net
variable: id=1234
HTTP 304

GET https://{{host}}/health
HTTP 200
```

#### Secrets {#file-format-templates-secrets}

Secrets are variables which value is redacted from standard error logs (for instance using [`--very-verbose`](#getting-started-manual-very-verbose)) and [reports](#getting-started-running-tests-generating-report).
Secrets are injected through command-line with [`--secret` option](#getting-started-manual-secret):

```shell
$ hurl --secret token=FooBar test.hurl
```

Values are redacted by _exact matching_: if a secret value is transformed, and you want to redact also the transformed value, 
you can add as many secrets as there are transformed values. Even if a secret is not used as a variable, all secrets values 
will be redacted from messages and logs.

```shell
$ hurl --secret token=FooBar \
       --secret token_alt_0=FOOBAR \
       --secret token_alt_1=foobar \
       test.hurl
```

> Secrets __are not redacted__ from HTTP responses outputted on standard output as Hurl considers the standard output as
> the correct unaltered output of a run. With this call `$ hurl --secret token=FooBar test.hurl`,
> the HTTP response is outputted unaltered and `FooBar` can appear in the HTTP response. Options that transforms Hurl
> output on standard output, like [`--include`](#getting-started-manual-include) or [`--json`](#getting-started-manual-json) works the same. [JSON report](#getting-started-running-tests-json-report) also saves each unaltered HTTP
> response on disk so extra care must be taken when secrets are in the HTTP response body. 


### Templating Body {#file-format-templates-templating-body}

Variables and functions can be used in [JSON body](#file-format-request-json-body):

~~~hurl
PUT https://example.org/api/hits
{
    "key0": "{{a_string}}",
    "key1": {{a_bool}},
    "key2": {{a_null}},
    "key3": {{a_number}},
    "key4": "{{newDate}}"
}
~~~

Note that we're writing a kind of JSON body directly without any delimitation marker. For the moment, [XML body](#file-format-request-xml-body) can't 
use variables directly. In order to templatize a XML body, you can use [multiline string body](#file-format-request-multiline-string-body) with variables and 
functions. The multiline string body allows to templatize any text based body (JSON, XML, CSV etc...):

Multiline string body delimited by `` ``` ``:

~~~hurl
PUT https://example.org/api/hits
Content-Type: application/json
```
{
    "key0": "{{a_string}}",
    "key1": {{a_bool}},
    "key2": {{a_null}},
    "key3": {{a_number}},
    "key4: "{{newDate}}"
}
```
~~~

Variables can be initialized via command line:

```shell
$ hurl --variable a_string=apple --variable a_bool=true --variable a_null=null --variable a_number=42 test.hurl
```

Resulting in a PUT request with the following JSON body:

```
{
    "key0": "apple",
    "key1": true,
    "key2": null,
    "key3": 42,
    "key4": "2024-12-02T13:39:45.936643Z"
}
```

   "License" shall mean the terms and conditions for use, reproduction,
   and distribution as defined by Sections 1 through 9 of this document.

   "Licensor" shall mean the copyright owner or entity authorized by
   the copyright owner that is granting the License.

   "Legal Entity" shall mean the union of the acting entity and all
   other entities that control, are controlled by, or are under common
   control with that entity. For the purposes of this definition,
   "control" means (i) the power, direct or indirect, to cause the
   direction or management of such entity, whether by contract or
   otherwise, or (ii) ownership of fifty percent (50%) or more of the
   outstanding shares, or (iii) beneficial ownership of such entity.

   "You" (or "Your") shall mean an individual or Legal Entity
   exercising permissions granted by this License.

   "Source" form shall mean the preferred form for making modifications,
   including but not limited to software source code, documentation
   source, and configuration files.

   "Object" form shall mean any form resulting from mechanical
   transformation or translation of a Source form, including but
   not limited to compiled object code, generated documentation,
   and conversions to other media types.

   "Work" shall mean the work of authorship, whether in Source or
   Object form, made available under the License, as indicated by a
   copyright notice that is included in or attached to the work
   (an example is provided in the Appendix below).

   "Derivative Works" shall mean any work, whether in Source or Object
   form, that is based on (or derived from) the Work and for which the
   editorial revisions, annotations, elaborations, or other modifications
   represent, as a whole, an original work of authorship. For the purposes
   of this License, Derivative Works shall not include works that remain
   separable from, or merely link (or bind by name) to the interfaces of,
   the Work and Derivative Works thereof.

   "Contribution" shall mean any work of authorship, including
   the original version of the Work and any modifications or additions
   to that Work or Derivative Works thereof, that is intentionally
   submitted to Licensor for inclusion in the Work by the copyright owner
   or by an individual or Legal Entity authorized to submit on behalf of
   the copyright owner. For the purposes of this definition, "submitted"
   means any form of electronic, verbal, or written communication sent
   to the Licensor or its representatives, including but not limited to
   communication on electronic mailing lists, source code control systems,
   and issue tracking systems that are managed by, or on behalf of, the
   Licensor for the purpose of discussing and improving the Work, but
   excluding communication that is conspicuously marked or otherwise
   designated in writing by the copyright owner as "Not a Contribution."

   "Contributor" shall mean Licensor and any individual or Legal Entity
   on behalf of whom a Contribution has been received by Licensor and
   subsequently incorporated within the Work.

2. Grant of Copyright License. Subject to the terms and conditions of
   this License, each Contributor hereby grants to You a perpetual,
   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
   copyright license to reproduce, prepare Derivative Works of,
   publicly display, publicly perform, sublicense, and distribute the
   Work and such Derivative Works in Source or Object form.

3. Grant of Patent License. Subject to the terms and conditions of
   this License, each Contributor hereby grants to You a perpetual,
   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
   (except as stated in this section) patent license to make, have made,
   use, offer to sell, sell, import, and otherwise transfer the Work,
   where such license applies only to those patent claims licensable
   by such Contributor that are necessarily infringed by their
   Contribution(s) alone or by combination of their Contribution(s)
   with the Work to which such Contribution(s) was submitted. If You
   institute patent litigation against any entity (including a
   cross-claim or counterclaim in a lawsuit) alleging that the Work
   or a Contribution incorporated within the Work constitutes direct
   or contributory patent infringement, then any patent licenses
   granted to You under this License for that Work shall terminate
   as of the date such litigation is filed.

4. Redistribution. You may reproduce and distribute copies of the
   Work or Derivative Works thereof in any medium, with or without
   modifications, and in Source or Object form, provided that You
   meet the following conditions:

   (a) You must give any other recipients of the Work or
   Derivative Works a copy of this License; and

   (b) You must cause any modified files to carry prominent notices
   stating that You changed the files; and

   (c) You must retain, in the Source form of any Derivative Works
   that You distribute, all copyright, patent, trademark, and
   attribution notices from the Source form of the Work,
   excluding those notices that do not pertain to any part of
   the Derivative Works; and

   (d) If the Work includes a "NOTICE" text file as part of its
   distribution, then any Derivative Works that You distribute must
   include a readable copy of the attribution notices contained
   within such NOTICE file, excluding those notices that do not
   pertain to any part of the Derivative Works, in at least one
   of the following places: within a NOTICE text file distributed
   as part of the Derivative Works; within the Source form or
   documentation, if provided along with the Derivative Works; or,
   within a display generated by the Derivative Works, if and
   wherever such third-party notices normally appear. The contents
   of the NOTICE file are for informational purposes only and
   do not modify the License. You may add Your own attribution
   notices within Derivative Works that You distribute, alongside
   or as an addendum to the NOTICE text from the Work, provided
   that such additional attribution notices cannot be construed
   as modifying the License.

   You may add Your own copyright statement to Your modifications and
   may provide additional or different license terms and conditions
   for use, reproduction, or distribution of Your modifications, or
   for any such Derivative Works as a whole, provided Your use,
   reproduction, and distribution of the Work otherwise complies with
   the conditions stated in this License.

5. Submission of Contributions. Unless You explicitly state otherwise,
   any Contribution intentionally submitted for inclusion in the Work
   by You to the Licensor shall be under the terms and conditions of
   this License, without any additional terms or conditions.
   Notwithstanding the above, nothing herein shall supersede or modify
   the terms of any separate license agreement you may have executed
   with Licensor regarding such Contributions.

6. Trademarks. This License does not grant permission to use the trade
   names, trademarks, service marks, or product names of the Licensor,
   except as required for reasonable and customary use in describing the
   origin of the Work and reproducing the content of the NOTICE file.

7. Disclaimer of Warranty. Unless required by applicable law or
   agreed to in writing, Licensor provides the Work (and each
   Contributor provides its Contributions) on an "AS IS" BASIS,
   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
   implied, including, without limitation, any warranties or conditions
   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
   PARTICULAR PURPOSE. You are solely responsible for determining the
   appropriateness of using or redistributing the Work and assume any
   risks associated with Your exercise of permissions under this License.

8. Limitation of Liability. In no event and under no legal theory,
   whether in tort (including negligence), contract, or otherwise,
   unless required by applicable law (such as deliberate and grossly
   negligent acts) or agreed to in writing, shall any Contributor be
   liable to You for damages, including any direct, indirect, special,
   incidental, or consequential damages of any character arising as a
   result of this License or out of the use or inability to use the
   Work (including but not limited to damages for loss of goodwill,
   work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses), even if such Contributor
   has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
   the Work or Derivative Works thereof, You may choose to offer,
   and charge a fee for, acceptance of support, warranty, indemnity,
   or other liability obligations and/or rights consistent with this
   License. However, in accepting such obligations, You may act only
   on Your own behalf and on Your sole responsibility, not on behalf
   of any other Contributor, and only if You agree to indemnify,
   defend, and hold each Contributor harmless for any liability
   incurred by, or claims asserted against, such Contributor by reason
   of your accepting any such warranty or additional liability.

END OF TERMS AND CONDITIONS

APPENDIX: How to apply the Apache License to your work.
