Flutter Testing

Overview

This skill provides comprehensive guidance for testing Flutter applications across all test types. Flutter testing falls into three categories:

• Unit tests - Test individual functions, methods, or classes in isolation
• Widget tests (component tests) - Test single widgets and verify UI appearance and behavior
• Integration tests - Test complete apps or large parts to verify end-to-end functionality

A well-tested Flutter app has many unit and widget tests for code coverage, plus enough integration tests to cover important use cases.
