带有通用接口的Rhino Mocks Stub会导致InvalidOperationException

本文关键字：Stub InvalidOperationException Mocks Rhino 接口 | 更新日期: 2023-09-27 18:21:03

我在使用通用接口时遇到了Rhino Mocks问题。为更新方法创建存根时，抛出InvalidOperationException

接口

public interface IDB<T> 
{
    String add(T obj);
    void update(String id, T obj);
}

工作单元测试

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

失败的单元测试

[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];
            });
    ...
}

很有趣，但我认为它希望您发送Arg而不是"1"

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