Write unit tests for React components by leveraging Vitest and React Testing Library to render components, simulate user interactions, and assert DOM output. This approach provides reliable component testing without needing a full browser environment.

Mock APIs and context in Vitest integration tests using centralized mock factories. These factories simulate API responses and React contexts, ensuring consistent and maintainable test environments across your integration testing flows.

Yes, centralized mock factories are required to simulate APIs, contexts, and user interactions. They ensure consistent and maintainable integration tests by standardizing how external dependencies are mocked across the test suite.

Improve test coverage for new features by applying consistent test templates and patterns for unit, component, and integration testing with Vitest. This adds coverage systematically and reduces the risk of regressions.

React Testing Library component tests fail when mock factories do not accurately simulate APIs or contexts. Ensure your centralized mock factories correctly wrap components with required providers and mock asynchronous API responses.

Debug failing Vitest tests for integration flows by isolating component interactions and verifying centralized mock factories. The testing strategy targets debugging failing tests to quickly identify issues in integration flows.
