Test-writing patterns for JS/TS, Python, Go, and Rust (unit, integration, E2E, visual regression). Use only when the user explicitly asks for tests or test coverage; for debugging without a test request, use debug-systematic.

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

# Test Specialist

Test-writing patterns for JS/TS, Python, Go, and Rust, plus bug-analysis habits that apply when tests are requested.

## When to Use

Use this skill only when the user explicitly asks for tests. Without that request, validate by reviewing the diff and the code it touches.

**Use for (when tests are requested):**

- Writing unit, integration, or E2E tests
- Improving test coverage
- Security and performance tests

**Don't use when:**

- Debugging without a test request → use `debug-systematic`
- Code review → use `generic-code-reviewer`
- Technical debt → use `tech-debt-analyzer`
- Feature development → use `generic-feature-developer`

## Testing Stack by Project

| Project Type  | Unit Tests  | Component       | E2E        |
| ------------- | ----------- | --------------- | ---------- |
| React/Next.js | Vitest/Jest | Testing Library | Playwright |
| Node.js       | Vitest/Jest | Supertest       | Playwright |
| Static        | Jest        | -               | Playwright |

How to install

The exact contents, by fingerprint
mdr add travisjneuman/.claude/test-specialist@sha256:ce6d4e39c41c25f4

The line at the top of this page pins the label git:20260930.c8d311d, 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.
