Designs and writes tests that catch real regressions: unit, integration or E2E placement, fixtures, behavior-first assertions, characterization and property tests. Use when asked to write tests, add coverage or a regression test.
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 Writing Write tests that fail when the behavior breaks and stay green through refactors. The deliverable is not coverage — it is a tripwire: for every realistic way the code under test could regress, at least one test goes red. A test that cannot fail against broken code is documentation wearing a test's costume. ## When to Activate - "Write tests for X", "add coverage", "this module has no tests". - A bug fix needs its regression test (awesome-bug-fix hands off here). - A review or audit finding says "needs a test" (awesome-code-review, awesome-security-audit, awesome-dependency-audit). - Legacy code needs a safety net before a refactor (characterization tests). Do not activate to review test quality in a diff (awesome-code-review Phase 4 owns that) or to find the root cause of a failure (awesome-bug-fix). ## Work Process 1. Discover the incumbent setup first — runner, assertion style, fixture/factory conventions, file placement, naming pattern. New tests match the repo's existing shape; never introduce a second test framework or a parallel convention. No runner at all → propose the ecosystem default and wait for approval (it is a new dependency). …

How to install
mdr add khasky/awesome-agent-skills/awesome-test-writing@sha256:2c1e23d8ee628b28The line at the top of this page pins the label git:20261018.a4259a5, 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.
