Flutter GenerateMocks不是生成模拟类

Question

我正在尝试在我的测试方法上使用@generatemocks，这是我的开发依赖项：

dev_dependencies:
  test: any
  flutter_test:
    sdk: flutter
  flutter_driver:
    sdk: flutter
  integration_test:
    sdk: flutter
  flutter_lints: ^1.0.4
  build_runner: ^2.1.4
  mockito: ^5.0.0
  mocktail: ^0.2.0

我正在使用这样的使用：

@GenerateMocks([CustomerPOAutocompleteState])
void main() {
  TestWidgetsFlutterBinding.ensureInitialized();

但是在运行flutter flutter pub run build build build build_runner build build没有生成什么都没有生成？

Answer 1

不知道这是否是它，但是我只是将import'my_test_file.mocks.dart'; @generatemocks 注释并效果很好。

之前：

@GenerateMocks([MyClass])

之后：

@GenerateMocks([MyClass])
import 'my_test_file.mocks.dart';

Answer 2

根据文档

如果您需要模拟getxController/getxService，则应扩展GetXController，然后将其与模拟混合在一起，以便

class NotificationServiceMock extends GetxService 
       with Mock implements NotificationService {}

我直接在dependencies上直接添加了mockito。

dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^1.0.2
  flutter_bloc: ^8.0.1
  equatable: ^2.0.3
  dartz: ^0.10.1
  mockito: ^5.2.0 #here


dev_dependencies:
  flutter_test:
    sdk: flutter
  build_runner: ^2.1.11

请确保在您的抽象类上创建一些方法，在我的情况下，它是restaurantrepository，并将像@generatemocks（[restaurantantrepository]）一样被注释。

然后

flutter pub run build_runner build

在测试文件上运行

import 'package:mockito/annotations.dart';
import 'package:mockito/mockito.dart';

@GenerateMocks([RestaurantRepository])
void main() {
  late MockRestaurantRepository mockRestaurantRepository;
//...}
