Where should I store my test data and JSON responses?

The skill suggests a standardized 'test/fixtures/' directory for organizing JSON files and mock data objects, keeping them separate from test logic.

What mocking library is recommended in these patterns?

The templates utilize Mocktail, which allows for type-safe mocking in Dart without the need for manual code generation.

Can I test UI responsiveness across different devices?

Yes, the included Golden test patterns use the Golden Toolkit to render and compare widgets across various device profiles, including iPhones and tablets.

Does this skill support different state management libraries?

Yes, while the examples provided focus on Riverpod, the patterns and directory structures are easily adaptable for Bloc, Provider, or other Flutter state management solutions.
