Can it help reduce flaky tests?

Yes, it identifies common causes of flakiness such as timing dependencies, improper async handling, and shared mutable state, providing strategies to fix them.

What is mutation testing and how is it used here?

Mutation testing modifies your source code to see if tests catch the changes. This skill helps you set up tools like Stryker and interpret results to improve test effectiveness.

How does it measure test maintainability?

It evaluates tests based on structure (AAA/GWT), naming conventions, DRY principles, and the presence of anti-patterns like 'mystery guest' or 'assertion roulette'.

Does this skill support specific frameworks like Jest or Playwright?

This skill provides framework-agnostic principles and analysis. For implementation-specific code, it works best alongside specialized skills like jest-testing or playwright-testing.
