Write unit and integration tests for a named module or change. Use when "write unit tests" or "add tests for this function". Coverage plan → plan-test-coverage. Mutation score → test-mutation. Browser check → test-playwright.
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-unit — Write tests that would notice a break **Degree of freedom: MIXED** — which cases to write `[HIGH freedom]`; detect-then-match existing harness `[LOW freedom — run exactly]`. This skill **writes tests**. Coverage theater / mutation score → `test-mutation`. Write effective, maintainable unit tests from the project's actual framework, production error data, and current best practices. ## This skill vs neighbors | Skill | Owns | |:------|:-----| | **test-unit** (this) | **Write** the tests | | `test-mutation` | Survivors / assertion theater — hand off the score | | `plan-test-coverage` | What *should* be tested — plan only, no harness | | `test-playwright` | Live this-diff PDCA, not unit files | | `test-qa` | Story/CRUD QA in a headed browser | ## How to reason (each test you add) 1. **Observe** — target function, existing pattern, Sentry gap if any 2. **Interpret** — behavior under test vs implementation detail 3. **Classify** — write (public/edge/error) / skip (trivial/third-party/markup) 4. **Severity** — prod-error gap and money/auth paths first ## Worked example > **Observe:** Sentry `TypeError` in `parsePrice`; `parsePrice.test.ts` only …

How to install
mdr add kensaurus/skills/test-unit@sha256:4398be4a6cc228c2The line at the top of this page pins the label git:20260923.68c095e, 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.
