Testing: TDD, E2E, preferred patterns, test-value audits, verification, agent testing.

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

Seven modes. Match the request to one mode and follow its section. Read
repository CLAUDE.md first -- project conventions override defaults here.

## Mode Selection

| Request matches | Go to |
|---|---|
| Write tests first, TDD, red-green-refactor | **TDD** |
| Flaky, brittle, test smell, over-mocking, slow tests | **Pattern Quality** |
| Audit or prune low-value, duplicate, or implementation-coupled tests | **Test Audit** |
| Test an agent, subagent testing, validate agent | **Agent Testing** |
| Run vitest, JavaScript/TypeScript tests | **Vitest Runner** |
| Playwright, E2E, end-to-end, browser test | **E2E (Playwright)** |
| Verify completion, final check, defense in depth | **Verification** |

---

## TDD

RED-GREEN-REFACTOR cycle with strict phase gates. Each feature gets its own
cycle. Do not batch multiple features into one cycle.

### Phase 1: RED -- Write a Failing Test

Write a test describing desired behavior before implementation exists. Use
Arrange-Act-Assert, descriptive names, one concept per test. Run the test and
show full output.

Every new or changed test, in any mode, must first pass the authoring gate in
`references/audit-test-value.md`.

How to install

The exact contents, by fingerprint
mdr add notque/vexjoy-agent/testing@sha256:85eb4ffdf226c8db

The line at the top of this page pins the label git:20261030.3e0868d, 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.
