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

[gitauto-ai]

Resolves #27

Why is this feature needed?

Widget tests are essential to ensure that our GFButton behaves as expected in various scenarios. By adding these tests, we can verify that the button displays the correct text and properly responds to user interactions (e.g., tapping), which helps maintain our code quality and prevents regressions in future updates.

What and how are we changing? Why this approach?

We added two new test files:

• test/components/badge/gf_button_test.dart
• test/components/button/gf_button_test.dart

Both tests create a minimal Flutter app environment using MaterialApp and Scaffold to house the GFButton widget. The tests:

• Render the widget.
• Check that the button displays the correct text ("Test Button").
• Simulate a tap on the GFButton to ensure that the onPressed callback is executed (by toggling a boolean value).

This approach leverages Flutter’s built-in widget testing framework, which is the standard method for automated UI testing, ensuring consistency and reliability.

What actions are required from users?

No manual actions are needed from users. However, developers should run the tests locally or via the CI pipeline to ensure that the widget functions correctly and that there are no regressions.

How does it work? (Technical details)

• The tests import 'package:flutter_test/flutter_test.dart' to use Flutter’s testing framework.
• A minimal UI is built using MaterialApp and Scaffold to render the GFButton in a complete widget tree, allowing full interaction simulation.
• The tester.pumpWidget() method initializes the widget, and tester.tap() simulates a user tap.
• The expectations confirm that the displayed text matches "Test Button" and that the onPressed callback is effectively triggered by changing a boolean value.

Is it backwards compatible?

Yes, these changes are fully backwards compatible. They only add new test files and do not alter any production code.

Any other considerations?

• Two test files are created in separate directories (badge and button) to cover potential organizational structures in the repository. This ensures that the GFButton widget is tested regardless of its directory location.
• Future enhancements might consolidate similar tests to reduce duplication if the repository structure changes.
• No additional dependencies were introduced outside of the standard Flutter testing packages.
