Comprehensive guidance for unit, widget, and integration testing across Flutter applications. This skill provides comprehensive guidance for testing Flutter applications across all test types. Flutter testing falls into three categories: A well-tested Flutter app has many unit and widget tests for code coverage, plus enough integration tests to cover important use cases. Flutter supports three build modes with different implications for testing: Unit tests test a single function, method, or class. Mock external dependencies and avoid disk I/O or UI rendering. Run with: flutter test Widget tests test single widgets to verify UI appearance and interaction. Integration tests test complete apps on real devices or emulators. Run with: flutter test integration_test/ What are you testing?
