Unit Testing (Vitest + RTL)

To write unit tests for React components using Vitest and RTL, you co-locate test files alongside your code and apply React Testing Library querying priorities with jest-dom-like assertions to validate UI behavior and interactions.

Testing React hooks with Vitest involves automating execution and reporting for integration scenarios using RTL-based querying and descriptive naming conventions to ensure fast feedback and prevent regressions across code changes.

Vitest works with React Testing Library to provide fast test execution and accessible queries for frontend integration tests, validating component behavior, interaction scenarios, and accessibility checks.

Yes, you can use jest-dom-like matchers with Vitest for component testing, applying RTL-based assertions and recommended querying priorities to validate component output and maintain discoverable test organization.

Co-locating tests alongside React component code keeps unit tests maintainable and discoverable, fulfilling conventions for test organization while ensuring fast feedback on component behavior and accessibility checks.
