Use when writing or running tests across languages and frameworks (Vitest, Jest, pytest, XCTest, Playwright), including TDD workflow, coverage, and test patterns.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# test-runner
Write and run tests across languages and frameworks.
## Framework Selection
| Language | Unit Tests | Integration | E2E |
|----------|-----------|-------------|-----|
| TypeScript/JS | Vitest (preferred), Jest | Supertest | Playwright |
| Python | pytest | pytest + httpx | Playwright |
| Swift | XCTest | XCTest | XCUITest |
## Quick Start by Framework
### Vitest (TypeScript / JavaScript)
```bash
npm install -D vitest @testing-library/react @testing-library/jest-dom
```
```typescript
// vitest.config.ts - minimal configuration for non-DOM tests
import { defineConfig } from 'vitest/config'
export default defineConfig({
test: {
globals: true,
},
})
```
Vitest uses the [Node environment by default](https://vitest.dev/guide/environment.html). For the React component example below or other DOM tests, retain the repository's configured DOM environment; select `environment: 'jsdom'` only when the target project already supplies a compatible `jsdom` dependency. Add [setupFiles](https://vitest.dev/config/setupfiles) only for an existing setup file with the required initialization and installed imports. The minimal configuration above does not create…

How to install
mdr add cruxexperts/localsetup/ls-write-run-tests@sha256:abbb5ae5c18f12dfThe line at the top of this page pins the label v1.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
