Rhino Mocks存根與通用接口導致InvalidOperationException

我遇到了使用通用接口時似乎是Rhino Mocks問題。當產生用於更新方法的引發InvalidOperationExceptionRhino Mocks存根與通用接口導致InvalidOperationException

接口

public interface IDB<T> 
{ 
    String add(T obj); 

    void update(String id, T obj); 
}

工作單位存根測試

[Test Method] 
public void AddWorks() 
{ 
    ... 
    var stubRepo = MockRepository.GenerateStub<IDB<Location>>(); 
    stubRepo.Stub(x => x.Add(Arg<Location>.Is.Anything)).Return("2342"); 
    ... 
}

失敗的單元測試

[Test Method] 
public void UpdateFails() 
{ 
    Location locObj = null; 
    ... 
    var stubRepo = MockRepository.GenerateStub<IDB<Location>>(); 
    stubRepo.Stub(x => x.Update("1", Arg<Location>.Is.Anything)) 
      .WhenCalled((x) => 
      { 
       locObj = (Location)x.Arguments[1]; 
      }); 
    ... 
}

滑稽，但我認爲它希望您發送精氨酸，而不是「1」

stubRepo.Stub(x => x.Update(Arg<string>.Is.Equal("1"), Arg<Location>.Is.Anything))
