Can I use this for end-to-end (E2E) testing?

This skill is specifically optimized for component and integration testing. For full E2E testing across multiple pages, tools like Playwright or Cypress are recommended.

Why does the skill prioritize getByRole?

Prioritizing ARIA roles ensures your tests interact with the UI like a real user and a screen reader would, naturally promoting web accessibility.

How does this handle API calls during tests?

The skill provides implementation patterns for Mock Service Worker (MSW) to mock at the network level, as well as Vitest mock functions for module-level isolation.

Does this skill support Jest?

Yes, while the primary examples focus on Vitest, the core React Testing Library queries and patterns are fully compatible with Jest environments.

安全与测试

Optimizes React component testing by implementing accessible queries, user event simulations, and robust async handling.

关于

The React Testing skill empowers Claude to write high-quality, maintainable tests for React components using React Testing Library and Vitest. It provides specialized guidance on selecting accessible queries like getByRole, simulating realistic user interactions with userEvent, and managing asynchronous state changes. By focusing on behavioral testing rather than implementation details, this skill helps developers ensure their UI components remain reliable, accessible, and performant throughout the development lifecycle.
