The Testing skill provides a comprehensive framework for implementing high-quality software verification within Claude Code. It guides developers through the Testing Pyramid—balancing unit, integration, and E2E tests—while enforcing the Arrange-Act-Assert (AAA) pattern for readable test code. With specialized guidance on mocking, test data builders, and naming conventions, this skill ensures that AI-generated tests are maintainable, efficient, and provide meaningful coverage for business logic and edge cases.
