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

[gitauto-ai]

Resolves #11

Why is this feature needed?

Adding this widget test for GFButtonBadge is essential to ensure the button's functionality works as expected. It helps us catch regressions during future changes and maintain the stability of our user interface components.

What and how are we changing? Why this approach?

We introduced a new test file (test/components/badge/gf_button_badge_test.dart) that performs a smoke test for the GFButtonBadge widget. The test verifies that:
• The widget renders correctly with the provided text.
• The onPressed callback is invoked upon tapping the button.

This approach gives us immediate feedback on the behavior of our widget and enforces a basic level of reliability for the component.

What actions are required from users?

No actions are required from users. This change only adds a new test to our test suite.

How does it work? (Technical details)

• The test uses Flutter's testWidgets function to set up and render the widget within a MaterialApp scaffold.
• A boolean flag (pressed) is toggled when the onPressed callback is executed. The test confirms that:
  - The widget displays the correct text ("Test").
  - Tapping the widget successfully triggers the callback, setting the flag to true.
• The pumpWidget and pump methods help simulate user interaction and ensure the UI updates as expected.

Is it backwards compatible?

Yes, this change is fully backwards compatible. It only adds additional tests and does not modify any existing functionality of the GFButtonBadge widget.

Any other considerations?

Future test enhancements might include more comprehensive checks (e.g., widget style, animations, or error handling). This initial test provides a solid foundation for further testing and ensures that critical functionalities are maintained over time.
