# React Testing

Comprehensive React testing patterns for behavior-focused component tests, custom hook tests, accessibility assertions, and network-level mocking.

## When to Activate

- Writing tests for React components, custom hooks, or pages
- Adding test coverage to legacy untested components
- Migrating from Enzyme or class-component-era patterns to React Testing Library
- Setting up Vitest or Jest for a new React project
- Mocking HTTP requests in tests
- Asserting accessibility violations
- Deciding which tests belong in RTL vs Playwright Component Testing vs full E2E
