What tools and approaches have you used when creating unit tests for your code?

When creating unit tests in Flutter, I used the flutter_test package, which provides convenient tools for writing and running tests.

Main approaches and tools:

• Using testWidgets for widget testing in an isolated environment.
• Mocking dependencies with packages like mockito to isolate the code under test.
• Breaking tests into small, independent scenarios to quickly identify errors.
• Automating test runs through CI/CD for quality control.

Example of a simple widget test:

import 'package:flutter_test/flutter_test.dart';
import 'package:my_app/my_widget.dart';

void main() {
  testWidgets('Text display check', (WidgetTester tester) async {
    await tester.pumpWidget(MyWidget());
    expect(find.text('Hello, world!'), findsOneWidget);
  });
}

This approach helps maintain code quality and quickly detect regressions.
