FAQPage Schema
How do I write React tests for components and hooks using Vitest?▼

React tests for components and hooks are written using Vitest and React Testing Library, with renderHook support for custom hooks and a dedicated test wrapper to ensure deterministic results.

What is the best way to mock API calls in React integration tests?▼

Mocking API calls in React integration tests is handled using MSW, which intercepts network requests to provide controlled API responses for unit and integration test scenarios.

Does this React testing approach work with custom hooks and state stores?▼

Yes, this React testing approach supports custom hooks using the renderHook utility and includes specific test strategies for store testing to validate state management behavior.

How do I set up a standard test stack for React unit and integration tests?▼

Setting up a standard React test stack involves configuring Vitest as the test runner, React Testing Library for component rendering, and MSW for API mocking across unit and integration tests.

Why do my React hook tests return inconsistent results?▼

React hook tests return inconsistent results when a dedicated test wrapper is not used; this Skill enforces a standard test wrapper to ensure deterministic outcomes during hook testing.
