Vitest is the test runner built for the Vite era. The API is intentionally Jest-compatible (describe, it, expect) so migration is mostly a config change, but Vitest runs on top of Vite's bundler so test feedback is much faster: HMR for tests, native ESM, native TypeScript, and instant cold starts. Browser mode (v3) replaces JSDOM with a real browser when you need it. Default for new TypeScript projects and the recommended runner for Next.js.
