e2e-testing-patterns

Master E2E testing with Playwright and Cypress to build reliable, fast test suites that catch bugs and enable fast deployment.

• End-to-end testing for critical user workflows
• Testing complex interactions and real API integrations
• Cross-browser and responsive design validation
• Establishing testing standards and CI/CD pipelines

• Test critical user journeys, not unit logic
• Use data-testid, not CSS selectors
• Keep tests independent and deterministic
• Optimize for speed and reliability
• Test user behavior, not implementation details
• Use page object model for maintainable code
• Leverage fixtures for test data setup and cleanup
• Apply waiting strategies based on conditions, not fixed timeouts

1. 1.Implement E2E tests for critical user flows
2. 2.Use page objects to organize test logic
3. 3.Set up test data with fixtures for reusable scenarios
4. 4.Apply conditional waits instead of fixed timeouts
5. 5.Configure CI/CD pipelines with parallel execution and retries
