The old doc says that, AutomatedTestWidgetsFlutterBinding for `flutter test` and LiveTestWidgetsFlutterBinding for `flutter run`. However, suppose we `flutter test integration_test/simple_test.dart` with the following code:

```
void main() {
  testWidgets('hi', (WidgetTester tester) async {
    print('hi ${TestWidgetsFlutterBinding.instance} ${Platform.operatingSystem}');
  });
}
```

We will see: `hi <IntegrationTestWidgetsFlutterBinding> ios`. Therefore, we see `IntegrationTestWidgetsFlutterBinding` is used in a `flutter test` command, which is contrary to the documentation.
