Write unit and integration tests that fail for the right reason — behaviour-level assertions, boundary values, the smallest honest double, deterministic setup and teardown. Use when adding tests for new code, pinning a bug before fixing it, or repairing tests that stay green while the code is broken. Not for deciding what to test or at which level, not for browser journeys, and not a way to call a change verified.
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 design A test earns its keep only by failing when the behaviour it names is broken. Most bad tests are not wrong; they are inert — they assert on what the code does rather than what it must do, so they go red on every refactor and green through every real defect. Keep the verbs apart: **created** is the test file written; **executed** is a run that happened; **tested** is a check that will run again without you; **verified** is a conclusion about the system, and a passing unit test does not supply it. ## When this fires Adding coverage for new or changed code, pinning a reported bug before fixing it, or fixing a suite that passes while the behaviour is wrong. It does not fire for choosing which risks to cover at which level (`test-strategy`), nor for end-to-end journeys (`e2e-testing`). ## Procedure 1. **Name the behaviour in one sentence in the caller's terms** — "a refund over the original amount is rejected", not "calls validateAmount". If the sentence needs an internal name to make sense, you are about to test the implementation. 2. **Make it fail first, for the reason you expect.** New test: run it before the code exists or …

How to install
mdr add nahid-sparktales/agent-dispatcher/test-design@sha256:37741f142d47e282The line at the top of this page pins the label git:20260919.a0d4f55, 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.
