Use when setting up tests for a frontend project - Vitest (Node unit and integration, real-browser UI via Playwright), Storybook stories as tests, Playwright e2e and MSW, under tests/ or colocated per the stack profile.
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
# Configure Test Stack
## 1. Audit current state
```bash
grep -E '"(vitest|@playwright/test|msw|@storybook/addon-vitest)"' package.json 2>/dev/null
ls vitest.config.* playwright.config.* tests/ .env.test .claude/stack-profile.md 2>/dev/null
find src -name "*.test.*" -o -name "*.spec.*" 2>/dev/null # co-located tests
```
Read `.claude/stack-profile.md` if present: `tests.layout` is `tests-dir` (default) or `colocated`; `frontend.framework` picks the render adapter; `package_manager` replaces `pnpm`. With `colocated`, or an established colocated suite, use the globs in `test-layout.md` ("Colocated variant") in step 6, create only `tests/{e2e,mocks,setup}` in step 5, and skip step 9 (no migration).
**Prerequisites:** the `@/` alias (`configure-typescript`) and `validate-env` (`.env.test`, step 5). MSW mocks the `fetcher` seam from `set-up-state-management`.
## 2. Decide what to do
- Nothing → full setup (steps 3–10).
- Partial → add only the missing layer (Vitest present but no browser `ui` project, or no e2e).
- Co-located tests found and the profile says `tests-dir` → migrate (step 9).
## 3. Detect framework

How to install
mdr add velimirmueller/claude-skills/configure-test-stack@sha256:56aa6fbd211cddccThe line at the top of this page pins the label git:20261009.d58ee01, 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.
