React TanStack Testing Skill

Testing React apps with TanStack libraries requires setup utilities, provider wrappers, and API mocking. This Skill provides comprehensive test templates and MSW-based mocks for server state management, routing, data tables, and form validation within Vite and Vitest environments, covering loading states, error handling, and user interactions end-to-end.

Yes. Automate testing for TanStack Query and Router by using this Skill's test setup utilities and mock data factories. Generate complete test suites that verify data fetching, protected routes, optimistic updates, and async validation with realistic API mocks, eliminating manual test case complexity.

Test TanStack Table and Form components using ready-made templates and checklists provided by this Skill. Combine provider wrappers, mock factories, and Vitest assertions to validate pagination, infinite scrolling, form validation, and user interactions within your React dashboard or data-driven application.

This Skill applies to TanStack React applications built with Vite and Vitest. The test setup utilities, provider wrappers, and MSW mocks are designed for that stack. Verify your project uses these tools before applying the templates and test suite recommendations.

Use MSW-based API mocking and mock data factories included in this Skill to simulate server responses. Generate realistic test scenarios for infinite scrolling, pagination, optimistic updates, and error states without hitting real endpoints, accelerating test development and reliability.

This Skill covers loading states, error handling, user interactions, optimistic updates, infinite scrolling, pagination, and async validation. Test server state management with TanStack Query, protected routes with Router, complex table interactions, and form validation—all with functional and technical requirements satisfied by templates and checklists.
