Analyzes and improves test suites by detecting test smells, overmocking, flaky tests, and coverage gaps.
This skill provides Claude with expert knowledge to evaluate test quality across multiple dimensions including correctness, reliability, and maintainability. It helps developers identify anti-patterns such as overmocking, fragile selectors, and race conditions in asynchronous tests while providing actionable fixes based on the FIRST principles and the AAA pattern. Whether you are reviewing existing tests or setting up a new test suite, this skill ensures your codebase remains robust and easy to maintain by enforcing high testing standards and optimal coverage.
