GitAuto: Add a widget test for lib/components/badge/gf_button.dart

[gitauto-ai]

Resolves #27

Why is this feature needed?

This feature ensures that key UI components, namely GFButtonBadge and GFButton, render correctly and behave as expected. By adding widget tests to the project, we can catch regressions early and maintain the stability of the UI, especially as the codebase evolves.

What and how are we changing? Why this approach?

• Added a new test file for GFButtonBadge at test/components/badge/gf_button_test.dart.
• Added a new test file for GFButton at test/components/button/gf_button_test.dart.

Each test file uses Flutter’s widget testing framework to:
• Build a minimal app environment (MaterialApp and Scaffold) containing the widget under test.
• Verify that the widget is rendered by checking for its text and type.

This approach was chosen because it directly verifies the expected output and behavior of the widgets with well-established Flutter testing techniques, providing clear feedback when issues arise.

What actions are required from users?

No immediate action is required from users. However, developers should run the test suite using the command “flutter test” to ensure that the new tests pass and that no regressions have been introduced in the UI components.

How does it work? (Technical details)

• For each test, a MaterialApp is created with a Scaffold to provide the necessary context to render the widget.
• The widget under test (either GFButtonBadge or GFButton) is instantiated with sample properties such as onPressed callbacks and text labels.
• The tester pumps the widget and subsequently checks for the presence of the specified text and the widget itself using Flutter’s “find” functions.
• These tests follow standard Flutter testing practices and can be easily integrated into the continuous integration pipeline.

Is it backwards compatible?

Yes, the addition of widget tests does not alter any existing functionality or introduce breaking changes. They strictly serve to ensure that existing components continue to display the expected behavior.

Any other considerations?

Future improvements may include expanding these basic tests to cover more complex interactions or different configurations of the widgets. For now, the focus is on verifying that the components render correctly with their essential properties.
