Nivetha Nagalingam enhanced the dotnet/maui repository by expanding automated UI test coverage and improving cross-platform reliability for critical controls such as CollectionView, Stepper, CarouselView, and GraphicsView. She migrated and modernized test suites using C#, XAML, and Appium, focusing on device-based and visual regression testing to catch UI inconsistencies early. Her work included developing feature matrix test suites, implementing translation parity checks for Android, and introducing baseline image snapshots for Windows and macOS. By addressing test flakiness and stabilizing CI pipelines, Nivetha’s engineering efforts strengthened release confidence and reduced regression risk across Android, iOS, and desktop platforms.

June 2025 monthly summary (dotnet/maui): Focused on expanding QA coverage for critical UI components and establishing cross-platform translation parity validation to reduce regression risk in Android deployments. Key features delivered: - Quality Assurance: Expanded UI Testing for Stepper and Android Translation, including a Stepper Feature Matrix UITest suite to validate value manipulation, enabled/visible states, and flow direction across UI scenarios; migrated Compatibility.Core tests to Android device tests with a translation parity check, leveraging a helper AssertTranslationMatches to verify MAUI-to-native translation parity. Major bugs fixed: - No major bugs reported this period. Efforts concentrated on proactive QA improvements to prevent regressions and strengthen release confidence. Overall impact and accomplishments: - Substantially increased test coverage for Stepper UI and translation paths, enabling faster CI feedback and reducing post-release regression risk. - Strengthened cross-platform consistency between MAUI and native rendering on Android, contributing to more stable feature delivery and user experience. Technologies/skills demonstrated: - UI testing and device testing (Stepper, Android translation parity) - Test migration and modernization (Compatibility.Core to device tests) - Translation parity validation (AssertTranslationMatches) - Test automation, CI readiness, and cross-platform QA practices.
