In their own words
Vitest
Vitest is a free and open-source testing framework powered by Vite, though it can also run without Vite. It can reuse Vite configuration, plugins, resolvers, and transform pipelines. Jest-compatible APIs cover assertions, snapshots, and mocking, which can support migration from Jest. Watch mode reruns tests related to changed source or test files, and TypeScript, JSX, and ES modules work out of the box. Browser Mode runs tests in a browser and supports Playwright and WebdriverIO providers. Component testing covers Vue, React, Svelte, Lit, Marko, and other frameworks. Vitest supports coverage through V8 or Istanbul, benchmarking powered by Tinybench, parallel execution, parameterized cases, and property-based checks. An official Visual Studio Code extension is available, and the framework can be tried in StackBlitz without local installation. The listed requirements are Vite 6.4.0 or later and Node 22.12.0 or later. Help is available through the Vitest Discord community and GitHub Discussions.
