How can I effectively test my Flutter app?

How can I effectively test my Flutter app?

You can use Flutter's built-in testing framework, which includes unit tests, widget tests, and integration tests.

What are the differences between unit tests and widget tests?

Unit tests focus on individual functions or classes, while widget tests verify the UI and interactions of widgets.

Can you give me an example of a widget test?

Sure! You can use the testWidgets function to create a widget test. Here's a simple example:

testWidgets('Counter increments smoke test', (WidgetTester tester) async {
  await tester.pumpWidget(MyApp());
  expect(find.text('0'), findsOneWidget);
  await tester.tap(find.byIcon(Icons.add));
  await tester.pump();
  expect(find.text('1'), findsOneWidget);
});
