TypeError: Type not serializable

[japo32]

Hi, I have the following test below that puts simple text into an object:

from nose2.compat import unittest
import boto3
import placebo

class S3PlaceboTestCase(unittest.TestCase):

    def setUp(self):
        super().setUp()
        self.session = boto3.Session()


class S3PlaceboRecordCase(S3PlaceboTestCase):

    def setUp(self):
        super().setUp()
        path = 'responses'
        self.pill = placebo.attach(self.session, data_path=path)
        self.pill.record(services='s3')
        self.s3 = self.session.client("s3")

    def tearDown(self):
        super().tearDown()
        self.pill.stop()

    def test_pill_record(self):
        self.s3.put_object(Bucket='my_bucket', ContentType='text/plain', Key='pill_test.txt', Body='Sample text')
        obj = self.s3.get_object(Bucket='my_bucket, Key='pill_test.txt')
        self.s3.delete_object(Bucket='my_bucket', Key='pill_test.txt')
        self.assertTrue(True)

And when I run the test I'm getting:

  File "/usr/share/stuff-site-adcontrol/.test-venv/lib/python3.4/site-packages/placebo/serializer.py", line 60, in serialize
    raise TypeError("Type not serializable")
TypeError: Type not serializable

Which is strange because it's simple text.

Might be related to #5

We managed to fix it temporarily by adding a decode in the serialize function and encode in the deserialize function.

def deserialize(obj):
...
    if class_name == 'StreamingBody':
        return StringIO(target['body'].encode('UTF-8'))
...
def serialize(obj):
...
    if isinstance(obj, StreamingBody):
        result['body'] = obj.read().decode('UTF-8')
        return result
...

Unfortunately the StreamingBody of obj here is an empty byte object:

obj = self.s3.get_object(Bucket='my_bucket, Key='pill_test.txt')
pp.pprint(obj['Body'].read())

produces:

b''

when I comment out pill.record() I get this:

b'Sample text'

But when I look at the recorded JSON file, the data is properly recorded:

"Body": {
            "__class__": "StreamingBody",
            "body": "Sample text",
            "__module__": "botocore.response"
        },
