Next-generation testing framework powered by Vite. Reuse Vite's config and plugins - consistent across your app and tests. But Vitest is not required. Expect, snapshot, coverage, and more - migrating from Jest is straightforward. Out-of-box ESM, TypeScript and JSX support powered by esbuild.

Features

  • Vite's config, transformers, resolvers, and plugins. Use the same setup from your app
  • Chai built-in for assertions, with Jest expect compatible APIs
  • JSDOM and happy-dom for DOM and browser API mocking
  • Browser Mode for running component tests in the browser
  • Components testing (Vue, React, Svelte, Lit, Vitesse, Marko)
  • Workers multi-threading via Tinypool (a lightweight fork of Piscina)
