vitest-testing-playbook

Writes, runs and debugs Vitest suites for TypeScript, React and monorepo projects: workspace test organization, path aliases, function and module mocks, fake timers, component tests with React Testing Library, coverage, parallelism, CI wiring and failure triage. Use when the user asks to "write unit tests with Vitest", "fix a failing test suite", "mock a module or timer", "set up coverage thresholds", or "test a React component". Not for browser end-to-end testing, load testing, or non-Vitest runners such as Jest or Playwright.
