To write Jest unit tests for React, use a minimalist approach with 1-2 comprehensive tests per component. Focus on core rendering and essential interactions using React Testing Library, while avoiding brittle tests for edge cases like loading or empty states.

The best way to mock fetch requests in React unit tests is to use built-in mocking utilities provided by your testing framework. This Skill supports mocking fetch requests to isolate component behavior and ensure tests remain fast and maintainable.

You should write 1-2 concise unit tests per React component. This minimalist approach ensures you cover critical functionality and core rendering without testing individual elements separately or creating brittle tests for loading and empty states.

No, this unit testing approach explicitly avoids testing loading states, empty states, or individual elements separately. It focuses solely on core rendering and essential interactions to maintain an efficient and maintainable test suite.

When using React Testing Library, you should follow clear query priority guidelines to select elements. This Skill provides specific guidelines on query priority and highlights anti-patterns to help you write efficient and accessible tests.
