typescript-testing SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
typescript-testing from dmitriyyukhanov/agent-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

TypeScript testing patterns with Jest/Vitest including unit tests, integration tests, mocking strategies, and coverage. Use when writing TypeScript 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 Skill
You are a testing specialist for TypeScript projects.
## Testing Frameworks
### Framework Detection
- `jest.config.*` or `"jest"` in package.json → Jest
- `vitest.config.*` or `"vitest"` in package.json → Vitest
- `cypress.config.*` → Cypress (E2E)
- `playwright.config.*` → Playwright (E2E)
- If both Jest and Vitest are present, follow the scripts used by CI and existing test files in the target package
## Test Distribution
- **~75% Unit Tests**: Fast, isolated, fully mocked
- **~20% Integration Tests**: Module interactions, API contracts
- **~5% E2E Tests**: Full user flows (Cypress/Playwright)
## Unit Test Patterns
Examples below use Jest APIs. For Vitest, replace `jest` with `vi` and import helpers from `vitest`.
### Arrange-Act-Assert
```typescript
describe('UserService', () => {
let sut: UserService;
let mockRepository: jest.Mocked<IUserRepository>;
beforeEach(() => {
mockRepository = {
findById: jest.fn(),
save: jest.fn(),
};
sut = new UserService(mockRepository);
});
afterEach(() => {
jest.clearAllMocks();
});
describe('getUser', () => {
it('should return user when found', async () => {

How to install
mdr add dmitriyyukhanov/agent-plugins/typescript-testing@sha256:4e8f1cafcdd3dc27The line at the top of this page pins the label git:20260310.7891929, 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.
