- Functional Tests: Verify that migrated functionality works as expected
- Performance Tests: Compare performance between original and migrated code
- Regression Tests: Ensure no functionality is lost during migration
- UI Tests: Verify user interface behavior and appearance
# Run all tests
dotnet test
# Run specific test category
