findById 还有浓缩咖啡,我们可以用, R.id.unique_element_id .

mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            new Text(
              'You have pushed the button this many times:',
            ),
            new TextFormField(
              decoration: new InputDecoration(
                  labelText: 'Enter your username'
              ),
            ),
            new TextFormField(
              decoration: new InputDecoration(
                  labelText: 'Enter your phone number'
              ),
              keyboardType: TextInputType.number,
            ),

            new Text(
              '$_counter',
              style: Theme.of(context).textTheme.display1,
            ),
          ],

像这样设置测试文件

    import 'package:flutter_driver/flutter_driver.dart';
    import 'package:test/test.dart';

    void main() {
      FlutterDriver driver;

      setUpAll(() async {
        driver = await FlutterDriver.connect();
      });

      tearDownAll(() async {
        if(driver != null){
          driver.close();
        }
      });


test('tap on the button, verify result', () async {
    final SerializableFinder username = find.byValueKey('usernametextfield');
    expect(username, isNotNull);
    //insert value into username

    final SerializableFinder phonenumber = find.byValueKey('phone');
    expect(phonenumber, isNotNull);
    //insert value into phonenumber
});

//insert value into username 和 //insert value into phonenumber 是我想要完成的实际测试用例。

integration_test 我创建了一个登录流示例

首先在dev下的pubspec.yaml中添加一个依赖项

       dev_dependencies:
         flutter_test:
           sdk: flutter
         test: ^1.9.4
         integration_test: ^1.0.1

包的结构应如下所示:

将此添加到test/test\u driver/integration\u test.dart中

               import'package:integration_test/integration_test_driver.dart';

                               Future<void> main() => integrationDriver();

4.将此添加到integration\u test/foo\u test.dart中

                                    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));
                                      });
                                    }

添加键就像我们在颤振驱动设置

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

Foo上次在终端中运行命令颤振驱动
--驱动程序=测试\驱动程序/集成\测试.dart
--目标=集成测试/foo测试.dart

不确定你是否找到了问题的答案,但我在这里发布了一个解决方案。希望有帮助。

基本上,你需要定义 key TextFormField widget,它将帮助您唯一地识别该widget,然后您可以对其执行操作。例子:

new TextFormField(
              key: Key('userNameTextField'),
              decoration: new InputDecoration(
                  labelText: 'Enter your username'
              ),
            ),

test('tap on the button, verify result', () async {
    final SerializableFinder username = find.byValueKey('userNameTextField');
    expect(username, isNotNull);
    await driver.waitFor(username);
    await driver.enterText('Test');

  // repeat above for `phoneNumber` widget.

    final SerializableFinder phonenumber = find.byValueKey('phone');
    expect(phonenumber, isNotNull);
    //insert value into phonenumber
});

我创建了一个输入文本的方法。也许这对某人有用。

  Future<void> enterText(SerializableFinder itemFinder, String text) async {
    final isTextFieldPresent = await isPresent(itemFinder);

    if (isTextFieldPresent) {
      await _driver.tap(itemFinder);
      await _driver.enterText(text);
      await _driver.waitFor(find.text(text));
    } else {
      expect(isTextFieldPresent, true, reason: 'Cannot find text field');
    }
  }

下面是我在上面使用的isPresent方法

  Future<bool> isPresent(SerializableFinder itemFinder,
      {int delayInMilis = 1000}) async {
    final timeout = Duration(milliseconds: delayInMilis);
    try {
      await _driver.waitFor(itemFinder, timeout: timeout);
      return true;
    } catch (exception) {
      return false;
    }
  }
