testing is agent-read markdown (skill) from notque/vexjoy-agent: Testing: TDD, E2E, preferred patterns, verification, agent testing..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Testing
Six 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** |
| 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.
**Gate** -- proceed only when all true:
- Test file created and saved
- Test executed
- Output shows FAILURE (not syntax/import error)
- Failure indicates missing implementation
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
