A proper testing stack rolled into one skill: Playwright for E2E, Vitest for unit tests, k6 for load testing, plus accessibility and visual regression tooling. The testing pyramid breakdown (70% unit, 20% integration, 10% E2E) is sensible, and the reference docs cover practical stuff like flakiness mitigation, mobile gestures, and Core Web Vitals. You get security checklists for OWASP Top 10, cross-browser matrices, and pre-release gates. Use this when you need a complete testing strategy instead of piecing together random examples from different tools. The CI/CD pipeline setup shows the intended workflow: fast unit tests first, then progressively slower gates. It's opinionated about ratios and tooling, which is actually helpful if you're setting up testing from scratch.
