我试图对我的flutter项目进行测试

Question

我尝试用我的 tdd 项目对 flutter 进行测试，但出现了这些错误

错误状态：没有从 `when()` 中调用任何方法存根。是调用了真正的方法，还是扩展方法？

这是我的仓库

abstract class HomeRepository {

    Future<Either<Failure,BaseModel>> testCase({required ApiRequest apiRequest});
}

这是我的用例

class TestCase {
  HomeRepository homeRepository;
  TestCase({required this.homeRepository});
  Future<Either<Failure,BaseModel>>call({required ApiRequest apiRequest})async{
    return await homeRepository.testCase(apiRequest: apiRequest);
  }
}

### 现在这是我的测试页面

class HomeTest extends Mock implements HomeRepository{
  @override
  Future<Either<Failure,BaseModel>> testCase({required ApiRequest apiRequest})async{
     return await Right(AppModel.otpVerify);
  }

}


void main(){
  ApiRequest apiRequest = ApiRequest(method: ApiMethod.post, endPoint: '/');
  late HomeTest homeTest;
  late TestCase testCase;
    setUp(() {
      homeTest = HomeTest();
      testCase = TestCase(homeRepository: homeTest);

    });


  test('testcase', () async {
    // Setup
    when(homeTest.testCase(apiRequest: apiRequest)).thenAnswer((_) async => right(AppModel.otpVerify));

    // Action
    final result = await testCase(apiRequest: apiRequest);

    // Verification
    expect(result, right(AppModel.otpVerify)); // Ensure the expected result matches the actual result
  });

}

我正在尝试正确运行测试

我找到了灵魂:) 只需替换这个导入即可

import 'package:mockito/mockito.dart';

到此

import 'package:mocktail/mocktail.dart';

**所以测试我纠正了一些错误，这是新的**

class MockAuthRepo extends Mock implements AuthRepositories {

  @override
  Future<Either<Failure, BaseModel>> testCase({required ApiRequest apiRequest}) async {
    return await Future.value(right(AppModel.otpVerify));
  }
}

void main() {
  late MockAuthRepo mockAuthRepo;
 late PhoneVerifyUseCase useCase;
  OtpPageModel otpPageModel = OtpPageModel(phoneNumber: '0939048067');
  ApiRequest apiRequest = ApiRequest(
    method: ApiMethod.post,
    endPoint: EndPoints.login,
    model: AppModel.loginModel,
    body: otpPageModel.toJson(),
  );
  setUp(() {
    mockAuthRepo = MockAuthRepo();
    useCase= PhoneVerifyUseCase(authRepositories: mockAuthRepo);

  });

  test('should get trivia for the number from the repository', () async{
    // Setup
    when(() => mockAuthRepo.phoneVerify(apiRequest: apiRequest))
        .thenAnswer((_) async => right(AppModel.loginModel));

    // Action
    final result = await useCase(apiRequest: apiRequest);

    // Verification
    expect(result, Right(AppModel.loginModel));

  });

}

回购协议是

abstract class AuthRepositories{

   Future<Either<Failure,BaseModel>> phoneVerify({required ApiRequest apiRequest});
   Future<Either<Failure,BaseModel>> otpVerify({required ApiRequest apiRequest});
   Future<Either<Failure,BaseModel>> getAppOptions({required ApiRequest apiRequest});

}

用例是 `

class PhoneVerifyUseCase{
AuthRepositories authRepositories ;
PhoneVerifyUseCase({required this.authRepositories});

Future<Either<Failure,BaseModel>>call({required ApiRequest apiRequest})async{
return await authRepositories.phoneVerify(apiRequest: apiRequest);
}

}`
