Can I use this for visual regression testing?

Yes, it includes comprehensive guidance on implementing Golden tests to catch unintended visual changes by comparing widget renders against baseline image files.

Which testing libraries are covered?

The skill covers the core flutter_test and integration_test packages, as well as industry-standard mocking libraries like Mockito.

How does this skill help with Flutter unit testing?

It provides standardized patterns for testing pure Dart logic in isolation, ensuring your business rules and data models are verified independently of the UI framework.

Does it support performance profiling?

Absolutely. It provides strategies for using Flutter DevTools to identify frame-rendering jank, profile expensive operations, and detect memory leaks.

How do I measure test coverage with this skill?

It provides specific commands and workflows to generate coverage reports using lcov, helping you identify untested code paths in your Flutter project.
