Walkthrough

The change adds PostgreSQL integration-test execution, bounded competition row locks, validation that prevents empty stages after publication, and tests for lock timeouts and concurrent publishing and tour deletion.

Changes

Hierarchy concurrency safeguards

Layer / File(s) Summary
PostgreSQL integration-test execution
.github/workflows/main.yml, pom.xml, src/main/resources/application-test.yml, src/test/java/com/itasocialacademy/oitassist/PostgresIntegrationTest.java
Maven separates integration tests from unit tests, starts PostgreSQL through Testcontainers, loads test settings, and reports Surefire and Failsafe results in CI.
Locking and deletion validation
src/main/resources/application.yaml, src/main/java/com/itasocialacademy/oitassist/competition/validation/HierarchyValidator.java, src/main/java/com/itasocialacademy/oitassist/competition/dao/repository/TourRepository.java, src/main/java/com/itasocialacademy/oitassist/competition/service/TourServiceImpl.java
HierarchyValidator applies a configurable PostgreSQL lock timeout and rejects deletion of the last tour when the competition is no longer in DRAFT. TourRepository provides the stage-tour count query, and TourServiceImpl.delete invokes the validation.
Concurrency and lock-timeout validation
src/test/java/com/itasocialacademy/oitassist/competition/service/CompetitionLockTimeoutIT.java, src/test/java/com/itasocialacademy/oitassist/competition/validate/CompetitionHierarchyConcurrencyIT.java, src/test/java/com/itasocialacademy/oitassist/competition/validate/HierarchyValidatorTest.java
Integration tests verify lock-timeout failures and the publish/delete race. Unit tests mock the native query used by HierarchyValidator.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to c4b1e

Integration tests may fail on newer Docker environments, the reporting workflow has avoidable supply-chain exposure, and the race regression test can pass for unrelated failures. These should be corrected before merge.

Poem

Locks wait briefly, then yield,
Tours guard the stage they shield.
Tests race beneath the rain,
PostgreSQL checks the chain.
Reports bloom when builds are done.

dorny/test-reporter v1.9.1 required permissions checks write actions read contents read

💡 Result:

The dorny/test-reporter action (including version 1.9.1) typically requires the following permissions in your workflow configuration to function correctly when creating Check Runs [1][2][3]: permissions: contents: read actions: read checks: write These permissions are necessary because the action needs to access repository contents, download test result artifacts (via actions: read), and create check runs (via checks: write) [2]. Important Considerations: 1. Forked Repository Security: Workflows triggered by pull requests from forked repositories are executed with a read-only token by default, which prevents the creation of Check Runs [1][4]. A common workaround is to use a two-workflow pattern: - A CI workflow that runs on the PR branch (with read-only tokens) to execute tests and upload results as build artifacts [1][2]. - A Test Report workflow that runs on the main branch (using workflow_run) with the necessary read/write permissions to download the artifacts and create the reports [1][2][3]. 2. Alternative Approaches: If you do not want to use the checks: write permission, you may be able to use the use-actions-summary: true option, which can generate a report summary in the workflow execution logs without requiring the write-level check permission [2][5]. 3. Token Permissions: If your repository settings are configured for default read-only tokens, you must explicitly define the permissions block in your YAML file as shown above to grant the action the required access [2][6]. Failure to do so will often result in an error like "Resource not accessible by integration" [7].

Spring Boot 4.0.1 dependency management Testcontainers testcontainers-postgresql PostgreSQLContainer package Docker 29 Testcontainers 1.19.1

💡 Result:

For projects using Spring Boot 4.0.1, managing Testcontainers dependencies and compatibility with newer Docker versions (such as Docker 29) requires attention to versioning and configuration [1][2][3]. Spring Boot 4.0.1 (released December 2025) provides managed dependencies that include Testcontainers 2.0.3 [1]. If your project is attempting to use Testcontainers 1.19.1, you may encounter significant compatibility issues when running against Docker Engine 29 [4][3]. Testcontainers 1.x versions are generally incompatible with Docker 29 because they default to an older Docker API version (1.32) that is no longer supported by recent Docker releases, which require a minimum API version of 1.44 [2][4]. Key recommendations for your stack: 1. Upgrade to Testcontainers 2.x: The official recommendation to resolve issues with Docker 29 is to upgrade to Testcontainers 2.x (e.g., 2.0.2 or later) [2][4][3]. Spring Boot 4.0.1 manages Testcontainers 2.0.3, so utilizing the Spring Boot BOM will automatically align your project with a compatible version [1]. 2. PostgreSQLContainer Usage: The PostgreSQLContainer is located in the org.testcontainers:testcontainers-postgresql artifact [5]. Ensure this is added to your test dependencies [5]. Example Maven dependency: org.testcontainers testcontainers-postgresql test 3. Workaround: If you cannot immediately upgrade to Testcontainers 2.x, you can force compatibility with Docker 29 by creating a.docker-java.properties file in your project or home directory containing the line api.version=1.44 [4][6]. However, this is considered a temporary workaround and upgrading to version 2.x is the preferred, permanent fix [2][3]. The PostgreSQLContainer class remains in the package org.testcontainers.containers [7][8]. Ensure you have both the core testcontainers library and the postgresql module in your project dependencies to avoid runtime errors [6].

Testcontainers 2.0.3 testcontainers-postgresql PostgreSQLContainer Java package org.testcontainers.postgresql official

💡 Result:

The Testcontainers PostgreSQL module is available under the group ID org.testcontainers and artifact ID testcontainers-postgresql [1]. The PostgreSQLContainer class resides in the package org.testcontainers.containers [2]. Regarding version 2.0.3, it is a valid release of the Testcontainers library, published on December 15, 2025 [3][4]. While Testcontainers 2.0.3 exists as a core library version [5], the PostgreSQL module follows its own versioning (e.g., 1.21.x series) [6][2]. To use the PostgreSQL module, you should add the following dependency to your project (example shown for version 2.0.5, the current stable recommendation) [1]: Maven: org.testcontainers testcontainers-postgresql 2.0.5 test Gradle: testImplementation "org.testcontainers:testcontainers-postgresql:2.0.5" Note that adding this dependency does not automatically include a JDBC driver for PostgreSQL; you must include an appropriate database driver in your project dependencies as well [1].

Align the PostgreSQL module with Spring Boot 4.

The explicit org.testcontainers:postgresql:1.19.1 dependency overrides Spring Boot 4.0.1’s managed Testcontainers 2.0.3 line. This legacy version can fail against Docker Engine 29 because of its older Docker API support. Replace it with org.testcontainers:testcontainers-postgresql and omit the version. The existing org.testcontainers.containers.PostgreSQLContainer import remains compatible.

Record and assert each operation outcome.

Line 105 and Line 114 discard every RuntimeException. An unrelated failure in changeStatus can leave the competition DRAFT with zero tours after deletion succeeds, and this test will pass without proving that the concurrency safeguard rejected the competing operation.

Capture each exception. Assert that exactly one service call returned successfully. Assert that the other call failed with an expected lock or hierarchy-validation exception.
