# E2E Testing Patterns
Build reliable, fast, and maintainable end-to-end test suites that provide confidence to ship code quickly and catch regressions before users do.
## When to Use This Skill
- Implementing end-to-end test automation
- Debugging flaky or unreliable tests
- Testing critical user workflows
- Setting up CI/CD test pipelines
- Testing across multiple browsers
- Validating accessibility requirements
- Testing responsive designs
- Establishing E2E testing standards
## Core Concepts
### 1. E2E Testing Fundamentals
**What to Test with E2E:**
- Critical user journeys (login, checkout, signup)
- Complex interactions (drag-and-drop, multi-step forms)
- Cross-browser compatibility
- Real API integration
- Authentication flows
**What NOT to Test with E2E:**
- Unit-level logic (use unit tests)
- API contracts (use integration tests)
- Edge cases (too slow)
- Internal implementation details
### 2. Test Philosophy
**The Testing Pyramid:**
```
/\
/E2E\ ← Few, focused on critical paths
/─────\
/Integr\ ← More, test component interactions
/────────\
/Unit Tests\ ← Many, fast, isolated
/────────────\
```
