# Rstest

Rspack-based Testing Framework

Provide first-class support for Rspack ecosystem

Quick Start[GitHubGitHub](https://github.com/web-infra-dev/rstest)

♻️

## Reuse your build setup

Use existing Rsbuild or Rspack config so aliases, transforms, and plugins stay consistent in tests.

🎯

## Test through the build pipeline

Run tests through Rspack's bundling model to match production behavior more closely.

⚡

## Fast by design

Rspack-powered bundling keeps startup and reruns fast, even in larger projects.

🧠

## Modern by default

TypeScript, ESM, CJS, CSS Modules, and modern JavaScript work out of the box.

🧰

## Testing essentials included

Assertions, snapshots, mocks, coverage, and lifecycle hooks are ready when you start.

🌐

## Real browser testing

Run tests in Chromium, Firefox, or WebKit through Playwright when jsdom isn't enough.
