Description
Write, advise on, and review tests for JavaScript/TypeScript web and React Native apps — what to test at each level (unit, component, integration, end-to-end), Vitest/Jest setup, Testing Library queries by role and user-event, mocking the network with MSW, testing hooks and forms, Next.js specifics (Server Components, Server Actions, route handlers), Playwright e2e (locators, auto-waiting, auth state, traces), testing against local Supabase and Stripe test mode, React Native Testing Library, and eliminating flaky tests. Use whenever the user asks to add tests, fix a failing or flaky test, set up Vitest/Jest/Playwright, decide what to test, or review test code.
