Applies repository-aware TypeScript test design, behavior evidence, isolation, and mock-boundary criteria. Use when writing or reviewing unit 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
# TypeScript Testing Rules
## Prerequisite Detection
Inspect `package.json`, the lockfile, test configuration, and existing test imports before selecting a framework or command. Apply Vitest-specific rules only when Vitest is configured; otherwise use the repository's configured TypeScript test harness while preserving the behavior, isolation, and evidence rules below. If no runnable harness is identifiable, report the inspected paths and missing command or configuration.
## Test Framework
- **Vitest**: Use when selected by repository configuration or existing tests
- Test imports: `import { describe, it, expect, beforeEach, vi } from 'vitest'`
- Mock creation: Use `vi.mock()`
## Basic Testing Policy
### Quality Requirements
- **Regression protection**: concentrate tests on critical paths, business logic, and behavior whose regression would matter. Add a test when an unguarded behavior creates a material regression risk
- **Independence**: Each test can run independently without depending on other tests
- **Reproducibility**: Control time, randomness, environment values, and external I/O so identical inputs produce the same observable result

How to install
mdr add shinpr/ai-coding-project-boilerplate/typescript-testing@sha256:90e1c25bc90ce500The line at the top of this page pins the label git:20261014.578fed5, 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.
