Mobile Testing Testing guide for React Native applications. When to Use Writing unit tests for components or utilities Creating integration tests for features Setting up test infrastructure Debugging test failures Improving test coverage Test Setup Component Test Template Hook Test Template Utility Test Template Mocking Patterns Mock External Module Mock Database Mock Navigation Running Tests Best Practices 1. Test Behavior, Not Implementation: Test what users see and do 2. Use testID for Selection: More reliable than text matching 3. Mock External Dependencies: Keep tests isolated and fast 4. Test Edge Cases: Empty states, errors, loading states 5. Keep Tests Simple: One assertion per test when possible 6. Clean Up: Use beforeEach/afterEach for setup/teardown Common Patterns Async Testing Testing Forms Testing Lists Troubleshooting Tests timing out: Increase timeout or check for unresolved promises Can't find element: Use screen.debug() to see rendered output Mock not working: Ensure mock is before import Async issues: Use waitFor or findBy queries Resources Jest Docs React Native Testing Library
