使用 Flutter 新的 integration_test 的示例集成测试？

Question

Sample integration test with Flutter new integration_test ?

Answer 1

1. First add a dependency in pubspec.yaml under dev

dev_dependencies:
  flutter_test:
    sdk: flutter
  integration_test:
    sdk: flutter
  test: ^1.9.4

2. Your package should have a structure that looks like this:

3. in test/test_driver/integration_test.dart

    import'package:integration_test/integration_test_driver.dart'; Future<void> main() => integrationDriver();

4.In integration_test/foo_test.dart example

                                    void main() {
                                      IntegrationTestWidgetsFlutterBinding.ensureInitialized();
  
                                      testWidgets("Sign in test example", (WidgetTester tester) async {
                                        final Finder signInEmailField = find.byKey(Key('signInEmailField'));
                                        final Finder signInPasswordField = find.byKey(Key('signInPasswordField'));
                                        final Finder signInSaveButton = find.byKey(Key('signInSaveButton'));
  
                                        await tester.pumpWidget(MyApp());
  
                                        await tester.pumpAndSettle();
  
                                        await tester.tap(find.byKey(Key('signInEmailField')));
                                        await tester.enterText(signInEmailField, "paras@gmail.com");
  
                                        await tester.tap(signInPasswordField);
                                        await tester.enterText(signInPasswordField, "123456");
  
                                        await tester.tap(signInSaveButton);
                                        print("button tapped");
                                        await tester.pumpAndSettle(Duration(seconds: 1));
                                        expect(
                                            find.byWidgetPredicate((widget) =>
                                                widget is AppBar &&
                                                widget.title is Text &&
                                                (widget.title as Text).data.startsWith("ToDoApp")),
                                            findsOneWidget);
  
                                        await tester.pumpAndSettle(Duration(seconds: 1));
                                      });
                                    }

5. Add key like we set in flutter_driver

    appBar: AppBar( title: Text( 'ToDoApp', key: Key("toDoKey"), ), backgroundColor: Colors.brown[400], ),

6. Foo last run the command in your terminal flutter drive
   --driver=test_driver/integration_test.dart
   --target=integration_test/foo_test.dart

Thanks.. happy Fluttering
