Implements robust, accessible UI component tests using React Testing Library and modern TypeScript patterns.
Acerca de
The TypeScript Component Testing skill equips Claude with the expertise to write high-quality tests that focus on user behavior rather than implementation details. By leveraging React Testing Library philosophy, it ensures tests are accessible, maintainable, and resilient to refactoring. The skill provides standardized patterns for accessible queries, realistic user interactions via user-event, and reliable asynchronous testing techniques for both Jest and Vitest environments.
