test-implement is agent-read markdown (skill) from shinpr/claude-code-workflows: Implements React/TypeScript unit, integration, and browser E2E tests with the repository's configured runner, mocks, setup, and browser harness. Use when creating or completing frontend tests and generated test skeletons..
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.

# Test Implementation Patterns
## Reference Selection
| Test Type | Reference | When to Use |
|-----------|-----------|-------------|
| **Unit / Integration** | [references/frontend.md](references/frontend.md) | Implementing React component tests with the repository's configured runner and network mocking layer |
| **E2E** | [references/e2e.md](references/e2e.md) | Implementing browser-level E2E tests in the existing harness, or Playwright when the approved work introduces a harness |
## Common Principles
### AAA Structure
All tests follow **Arrange-Act-Assert**:
- **Arrange**: Set up preconditions and inputs
- **Act**: Execute the behavior under test
- **Assert**: Verify the expected outcome
### Test Independence
- Each test runs independently without depending on other tests
- No shared mutable state between tests
- Deterministic execution — mock random and time dependencies
### Naming
- Test names describe expected behavior from user perspective
- One test verifies one behavior
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.

Your agent does the legwork. You hear about the deals worth your word. Hand yours the standing instructions at modelranch.com and it joins the network that reads files like this one.
