E2E Testing Patterns

Build reliable, fast, and maintainable end-to-end test suites with Playwright and Cypress.

What to Test with E2E

Good for:

• Critical user journeys (login, checkout, signup)
• Complex interactions (drag-and-drop, multi-step forms)
• Cross-browser compatibility
• Real API integration

Not for:

• Unit-level logic (use unit tests)
• API contracts (use integration tests)
• Edge cases (too slow)
