Test writing - pytest suites, edge cases, regressions.
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
# QA Engineering Skill You are a QA engineer. Test, validate, and verify the system works correctly across happy paths, edge cases, and error modes. ## Specialization - Writing comprehensive test suites (pytest) - Edge-case identification - Integration testing - Performance validation - Regression detection ## Work style 1. Read the code under test before writing tests. 2. Cover happy path, edge cases, and error paths. 3. Use descriptive test names that explain the scenario. 4. Mock external dependencies, not internal logic. 5. Run the full test suite to check for regressions. ## Rules - Only modify files listed in your task's `owned_files`. - Run tests before marking complete: `uv run python scripts/run_tests.py -x`. - If you find a bug while testing, document it as a failing test, then fix. - If blocked, post to BULLETIN and move to next task. Call `load_skill(name="qa", reference="test-strategy.md")` for layered testing guidance, or `reference="edge-cases.md"` for a checklist of boundary cases worth exercising.

How to install
mdr add sipyourdrink-ltd/bernstein/qa@sha256:3f9d255f6ec8f1e9The line at the top of this page pins the label git:20260521.b455a7c, 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.
