Vitest

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)
