- ✓ Component interaction testing
- ✓ Contract testing
- ✓ Microservices communication
End-to-End Testing (Top)
- ✓ Complete user journey testing
- ✓ UI automation testing
- ✓ Cross-browser compatibility
- ✓ Performance validation
- ✓ User acceptance scenarios
Manual Testing (Exploratory)
- ✓ Usability testing
- ✓ Exploratory testing
- ✓ Ad-hoc testing scenarios
- ✓ User experience validation
- ✓ Edge case discovery
