Frontend Vitest browser-mode tests, Testing Library queries, mockSdkService, makeMe builders, deterministic Vue component testing. Use when writing or changing frontend Vitest tests.
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.
What the file says
# Frontend Testing Rules
**Style ("small test" practice — stable boundary, data over mocks, focused assertions, concise makeMe):** the `unit-testing` skill — follow that first.
These commands cover behavioral testing only. Before accepting frontend proof,
also pass the typecheck required by the `frontend` skill's "Frontend proof" rule.
## Test Commands
From the repo root:
```bash
CURSOR_DEV=true nix develop -c pnpm frontend:test
```
All frontend unit-test commands use headless Chromium and never automatically open
a browser window. Do not enable a visible browser unless the user explicitly asks.
The legacy UI command also runs headlessly:
```bash
CURSOR_DEV=true nix develop -c pnpm frontend:test:ui
```
Run tests in headless watch mode (the Vitest UI remains available at its printed
URL without opening a browser):
```bash
CURSOR_DEV=true nix develop -c pnpm frontend:test:watch
```
Run a single test file from the repo root:
```bash
CURSOR_DEV=true nix develop -c pnpm frontend:test tests/path/to/TestFile.spec.ts
```
Or only the frontend package:
```bash
CURSOR_DEV=true nix develop -c pnpm -C frontend test tests/path/to/TestFile.spec.ts
```
Run a specific test case:

How to install
mdr add nerds-odd-e/doughnut/frontend-testing@sha256:41125b2f7f4496b2The line at the top of this page pins the label git:20261020.d6ceff8, 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.
