如何最小化注入到另一个的多级接口继承方法class

Question

我的第一个界面

public interface IBaseRepository
{ 
 Task<T> FirstOrDefault<T>(Expression<Func<T, bool>> predicate, Expression<Func<T, object>>[] 
 includeProperties = null) where T : class;
}

我的第二个界面

public interface IGenericRepository : IBaseRepository
{
 //Some methodes;
}

我的服务class和上面注入的方法IGenericRepository

public class AService
{
 private readonly IGenericRepository _genericRepository;
 public AService(IGenericRepository genericRepository)
 {
  _genericRepository = genericRepository;
 }
 public async Task<decimal> SaveRequest(Guid genericId)
 {
  .
  .
  var requestType = await _genericRepository.FirstOrDefault<RequestType>(x => 
  x.RequestTypeUuid == genericId); //in this line getting error message.
  .
  .
 }
}

我的最小起订量设置在测试 class 上面的服务方法

public class AServiceTests
{
 private readonly Mock<IGenericRepository> mockGenericRepository;
 private readonly MockRepository mockRepository;
 public AServiceTests()
 {
  this.mockRepository = new MockRepository(MockBehavior.Strict);
  this.mockGenericRepository = this.mockRepository.Create<IGenericRepository>();
 }
 private AService CreateAService()
 {
  return new AService(this.mockGenericRepository.Object);
 }
}

我的测试用例方法

[Fact]
public async Task SaveRequest_SendingValidData_ExpectedNotNull()
{
 // Arrange
 Guid genericId = new Guid("74jdjd83-8383-3hg7-83jj-e69427931176");
 var fakeReturnRequestType = GetFakeReturnRequestType();
 mockGenericRepository.Setup(x => x.FirstOrDefault<RequestType>(f => f.RequestTypeUuid == 
 genericId, null)).ReturnsAsync(fakeReturnRequestType);
 var objAService = this.CreateAService();
 var result = await objAService.SaveRequest(genericId);

 //Assertion
 . 
 .
}

获取模拟问题：

Message: Moq.MockException : IBaseRepository.FirstOrDefault(x => (x.RequestTypeUuid == value(Services.Impls.AService+<>c__DisplayClass10_0).genericId), null) invocation failed with mock behavior Strict. All invocations on the mock must have a corresponding setup. . . AbstractInvocation.Proceed() IGenericRepositoryProxy.FirstOrDefault[T](Expression1 predicate, Expression1[] includeProperties) . . --- End of stack trace from previous location where exception was thrown ---

Answer 1

x.FirstOrDefault<RequestType>(It.IsAny<Expression<Func<RequestType, bool>>>(), ...)

对我有用。
