Repository-aware rules for choosing which tests a change needs, one owning test per claim, observable proof, and test integrity. Use when writing, reviewing, or fixing tests.
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
# Testing Tests guarantee accepted behavior, and the next agent reads every existing test as a requirement to preserve. A brittle, duplicated, or implementation-shaped test therefore becomes a false requirement: it gets worked around, and the workaround leaves debt in the implementation. Keep the set of tests whose proof is worth its maintenance. ## Reference Read [references/typescript.md](references/typescript.md) only for TypeScript tests in web frontend work, including React, RTL, MSW, and Playwright tests. It does not apply to backend or non-web TypeScript tests. ## Governing Sources Use test commands, thresholds, boundaries, fixtures, and conventions from the repository, task, Work Plan, Design Doc, or test skeleton. When these sources are silent, select the smallest repository-supported proof without introducing a new project-wide default. ## Test Selection - Prove accepted behavior by default through integration and E2E tests at the boundary users and callers observe. Add a unit test for logic whose cases one representative boundary test cannot prove, such as calculations, parsing, or branching rules. …

How to install
mdr add shinpr/codex-workflows/testing@sha256:1be3c8c69151ce29The line at the top of this page pins the label git:20261013.5a1e725, 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.
