What Code Review Testing does

Code Review Testing gives guidance for authoring tests for agent changes, with a preference for integration tests in core/suite. It is used when changes affect agent logic and need readable, maintainable test coverage.

Code Review Testing is cataloged under Quality on DirSkills. Code Review Testing comes from a repository tagged agent-harness, ai-agents, autonomous-agents, bug-bounty and claude-code.

Documentation

README

From the original repository

For 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.
