Transloco i18n best practices for Angular. Covers runtime translation, lazy-loaded translation files per route, and test mocking. Activates when working with @jsverse/transloco. Install alongside angular-best-practices for full coverage.
Load PROACTIVELY when task involves writing tests, improving coverage, or test infrastructure. Use when user says "add tests", "write unit tests", "set up E2E testing", "improve coverage", or "add mocks". Covers Vitest/Jest unit tests, React Testing Library component tests, Playwright E2E tests, MSW API mocking, test organization and naming, fixture management, coverage targets and thresholds, snapshot testing, and CI integration.
Provides patterns for unit testing service layer with Mockito. Validates business logic in isolation by mocking dependencies. Use when testing service behaviors and business logic without database or external services.
Testing use cases and application services: use case testing with mocked gateways, DTO testing, application exception testing, orchestration testing, mocking at adapter boundaries. Coverage target: 85-90%. Use when: Testing use cases, testing application services, testing DTOs and data transformation, testing error handling in use cases, mocking external dependencies at layer boundaries.
Fix ServiceResult pattern mistakes causing test failures and type errors. Use when seeing "dict object has no attribute success", "mock not returning ServiceResult", mock assertions failing, or type errors with ServiceResult. Analyzes .py test files and service implementations. Covers async/await patterns, monad operations (map, bind, flatmap), and proper mock configuration.
Sets up async tests with proper fixtures and mocks using pytest-asyncio patterns. Use when testing async functions, creating async fixtures, mocking async services, or handling async context managers. Covers @pytest_asyncio.fixture, AsyncMock with side_effect, async generator fixtures (yield), and testing async context managers. Works with Python async/await patterns, pytest-asyncio, and unittest.mock.AsyncMock.
Create factory fixture patterns for customizable test setup with variations. Use when building reusable test fixtures with multiple configurations, creating parameterizable mocks, or implementing test data builders. Works with pytest fixtures, mock objects, and test utilities. Enables DRY test setup while maintaining flexibility for edge cases.

Write and maintain tests with Vitest v4 dual configuration, mock utilities, and Zustand store testing patterns.
Use when writing or reviewing Java unit tests. Enforces Mockito/JUnit 5 best practices - strict stubbing, no lenient mode, specific matchers, complete flow stubbing, Arrange-Act-Assert structure, and clear test naming.
