This skill provides Claude with a comprehensive framework for writing and reviewing unit tests based on industry best practices. It guides the model to focus on testing behavior rather than implementation details, implement the Arrange-Act-Assert (AAA) pattern, and apply strict mocking discipline to ensure test isolation. By automatically detecting project-specific tools like Vitest, Jest, or Pytest, it adapts these universal standards to your specific codebase, helping you maintain a high-quality, non-flaky test suite that serves as reliable documentation for your software's contract.
