To write unit tests for React components, you validate component props, event handling, and rendering stability using Vitest with React Testing Library to ensure UI regressions are caught.

Testing Zustand store state and actions involves verifying state mutations and action behaviors to expand coverage beyond snapshots, ensuring robust store integration within your React application.

Yes, you can test custom React hooks using Jest configurations. The testing workflow supports both Vitest and Jest setups to apply reusable hook testing patterns and validate hook behavior.

Yes, the workflow supports mocks for Zustand stores and custom hooks. Mocking stores and hooks isolates component logic and ensures robust test coverage across your Vitest or Jest test suites.

You need jsdom to provide a simulated DOM environment, enabling React Testing Library to render components and execute user-event interactions during Vitest unit test execution.

Snapshot testing often misses behavioral regressions in React components and Zustand stores. Validating props, state mutations, and event processing provides deeper coverage than relying on snapshots alone.
