Use when creating, modifying, reviewing, or deciding whether to add tests, fixtures, mocks, integration tests, end-to-end tests, smoke tests, or test plans in any codebase or language, including regression tests for bug fixes. Guides agents to choose the right test layer, avoid low-value tests, and verify meaningful behavioral oracles.
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 Quality ## Goal Write tests that protect important behavior, not tests that merely increase coverage or restate implementation details. A good test should answer: > If this plausible bug happened, would this test fail for a clear reason? ## Decide before writing Before adding a test, work through this in order: 1. **Name the behavior and a plausible defect** — a user failure, data loss, protocol or security break, race, persistence error, malformed input, or costly operational failure. If you cannot name a concrete defect, do not add the test. 2. **Search existing coverage** — direct tests and outcome-level assertions that already protect this behavior. 3. **Define an oracle that covers the bug population.** It must distinguish broken from fixed behavior (an exact observable outcome, not "does not crash") and be drawn from the population where the bug actually manifests. Validating a fix only against inputs that *don't* exhibit the bug — e.g. a decoder checked only against rows that already carry the decoded text, when the bug lives in rows that don't — proves nothing about the fix. If no oracle exists for the bug population, say so explicitly; sampling it by eye is… …

How to install
mdr add moonray/repoprompt-workflows/test-quality@sha256:f7fa2b08448758dfThe line at the top of this page pins the label git:20261007.59c4e76, 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.
