Design, implement, and evaluate risk-based software tests across unit, integration, contract, end-to-end, and regression layers. Use when adding tests, reproducing bugs, improving coverage, diagnosing flaky tests, or defining a test strategy; do not use to change production behavior unless the user also requests implementation.
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 Software ## Test contract - Define the behavior, invariant, or defect before selecting a test layer. - Use the lowest layer that observes the risk without hiding the integration boundary under test. - Test behavior rather than private implementation details. - Avoid snapshots that hide meaningful assertions. - Do not mock the component whose integration contract is under test. - Control time, randomness, concurrency, and external dependencies explicitly. - Keep fixtures minimal and readable. - Do not “fix” flaky tests by adding blind retries or sleeps. - Do not claim a regression test without proving it fails against the broken behavior when feasible. - Treat tests as potentially state-changing: they may write databases, queues, files, snapshots, browsers, or external sandboxes. - Do not run tests against production, shared customer data, or external services without explicit authorization and a verified isolation strategy. - Stop when the configured test target or cleanup behavior is ambiguous. ## Execute and report Read [references/test-strategy.md](references/test-strategy.md) when choosing test layers or specialized methods, investigating flakes, or planning …

How to install
mdr add phelan164/codex-howto/test-software@sha256:72bc9a51a8acf62aThe line at the top of this page pins the label git:20260731.42e092c, 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.
