About code-review-testing
A testing skill for changes to Codex agent behavior, with guidance on integration and unit test placement. It requires integration tests for logic changes and a list of major changes and user-facing behaviors to cover.
Key features
- 01Prefer integration tests for agent changes
- 02Require integration tests for logic changes
- 03List major changes and behaviors to test
- 04Use dedicated *_tests.rs files when needed
Use cases
- 01Testing changes to agent logic
- 02Checking user-facing behavior changes
- 03Organizing Codex integration and unit tests

Details
From the project READMEFor agent changes prefer integration tests over unit tests. Integration tests are under core/suite and use test_codex to set up a test instance of codex.
Features that change the agent logic MUST add an integration test:
- Provide a list of major logic changes and user-facing behaviors that need to be tested.
If unit tests are needed, put them in a dedicated test file (*_tests.rs). Avoid test-only functions in the main implementation.
Check whether there are existing helpers to make tests more streamlined and readable.
