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

[gitauto-ai]

Resolves #19

Why is this feature needed?

To ensure that the GFButtonBadge widget renders as expected and to prevent regressions in its behavior, it is important to include widget tests. This test verifies that the correct widget tree is built and that the core elements (like the badge text) are present.

What and how are we changing? Why this approach?

We have added a new widget test for GFButtonBadge in the file test/components/badge/gf_button_badge_test.dart. The test uses Flutter's testWidgets function to pump a MaterialApp containing the GFButtonBadge widget, then checks for the correct rendering by asserting the presence of expected text ("Test Badge") and the GFButtonBadge widget itself. This approach directly verifies the visual and functional behavior of the widget in an isolated environment, making it easier to spot issues early in the development cycle.

What actions are required from users?

No additional actions are required from users. The test is meant for developers and CI pipelines to verify that the widget behaves as expected after changes.

How does it work? (Technical details)

• The test creates a MaterialApp context with a Scaffold that houses the GFButtonBadge.
• Using tester.pumpWidget(), the widget is built and rendered.
• The test then checks if the rendered output contains the text "Test Badge" and ensures the widget type GFButtonBadge is present.
• This simple verification asserts both the widget's appearance and its basic functionality.

Is it backwards compatible?

Yes, this widget test addition is completely backwards compatible. It does not alter any existing functionality but only adds an extra layer of validation to ensure the GFButtonBadge continues to work as expected.

Any other considerations?

This initial test can be expanded in the future to include more detailed interactions such as verifying callback functions on user interaction. For now, it provides a basic sanity check which is sufficient for the intended purpose.
