What Rstest is

Rstest is a free, open-source JavaScript and TypeScript testing framework built on Rsbuild and Rspack. It bundles tests through Rspack’s dependency graph and applies SWC transforms, and it can reuse configuration from Rsbuild, Rslib, or Rspack, including aliases, transforms, and plugins. Tests can run in Node.js, simulated DOM environments with jsdom or happy-dom, and real browsers. Browser Mode uses Playwright for Chromium, Firefox, and WebKit; an integration also supports end-to-end tests against local, preview, or deployed URLs. Rstest can load Module Federation remotes in Node, JSDOM, and Browser Mode tests. Its built-in tools include Jest-compatible assertions, snapshots, mocks, spies, file-level isolation, lifecycle hooks, reporters, filtering, and coverage reporting. Multi-project testing, sharding, report merging, and coverage thresholds support CI workflows. The Rstack VS Code extension lets users browse, run, and debug tests. Quick start requires Node.js 20.19.0 or newer, with the LTS version recommended. Rstest is available under the MIT license.
