Best Practices

1. Page Object Pattern: Use page objects for maintainable test code
2. Test Independence: Ensure tests can run independently and in parallel
3. Data Management: Use proper test data setup and cleanup
4. Waiting Strategies: Use explicit waits instead of fixed delays
5. Cross-browser Testing: Test on multiple browsers and devices
6. CI/CD Integration: Automate test execution in pipelines
7. Reporting: Generate comprehensive test reports and artifacts

Test Strategy Framework
