Flutter unit tests verify functions, classes, and business logic in isolation using the flutter_test package. Place test files in the test/ directory and execute them with the flutter test command to validate logic independently.

Widget tests validate individual UI components and interactions within Flutter, while integration tests ensure end-to-end flows across multiple screens and plugins using the integration_test package.

Mocking dependencies and plugin interactions in Flutter tests involves substituting real services with mocked equivalents to reflect real-world usage. This ensures reliable end-to-end flows without relying on external systems.

Yes, integration tests in Flutter cover end-to-end flows across multiple screens and plugins. Implement them using the integration_test tooling and run with flutter test integration_test to verify comprehensive user journeys.

Structure your Flutter testing suite by separating unit tests for isolated logic, widget tests for UI interactions, and integration tests for end-to-end flows. Use flutter_test for unit and widget tests, and integration_test for comprehensive coverage.
