为什么RhinoMocks会在我的测试中抛出InvalidOperationException?

[Test]
public void AddLockClassWithNullNameShouldCallInsertOnSessionWithEmptyString()
{
    LockClass lockClass = new LockClass { Id = ValidId, Name = null };

    using ( mockRepository.Record() ) {
        sessionFactory.CreateSession();
        LastCall.Return( session );

        session.InsertWithId( lockClass );
        LastCall.Return( lockClass );

        session.Commit();
        session.Dispose();
    }

    using ( mockRepository.Playback() ) {
        controller = new LockClassPanelController( sessionFactory );
        controller.AddLockClass( lockClass.Id, string.Empty );
    }

    mockRepository.VerifyAll();
}

在以下位置运行测试结果:

Test 'Test.Unit.Controllers.LockClassPanelControllerTests.AddLockWithNullNameClassShouldCallInsertOnSessionWithEmptyString' failed:

有什么想法吗?

我刚刚发现,如果改变方法的第一行,效果会很好:

LockClass lockClass = new LockClass { Id = ValidId, Name = string.Empty };

( string.Empty null ) Name 属性为null,因此 姓名 除了 无效的 不会很有帮助。

编辑:

LockClass LockClass=new LockClass{Id=ValidId,Name=string.Empty};

那是我期望的目标。 LockClass 是一个DTO,只有在上面的行中初始化的两个属性,并且 Equals
表演路线应该是

controller.AddLockClass( lockClass.Id, null );

[设置]创建所有模拟对象。我要测试的是,如果用户通过GUI手势(GUI调用 AddLockClass

要使其完整:

private const int ValidId = 4711;
private const int InvalidId = 0;
private MockRepository mockRepository;
private ISessionFactory sessionFactory;
private ISession session;
private LockClassPanelController controller;

[SetUp]
public void Setup()
{
    mockRepository = new MockRepository();
    sessionFactory = mockRepository.StrictMock<ISessionFactory>();
    session = mockRepository.StrictMock<ISession>();
}

public void AddLockClass( int id, string name )
{
    if ( id != 0 ) {
        using ( var session = sessionFactory.CreateSession() ) {
            session.InsertWithId( new LockClass { Id = id, Name = name } );
            session.Commit();
        }
        LoadLockClasses();
        view.Initialize();
    }
}

Rhino Mocks为您提供了正确的异常。在AddLockClass中,您有以下行:

session.InsertWithId( new LockClass { Id = id, Name = ( name ?? string.Empty ) } );

LockClass lockClass = new LockClass { Id = ValidId, Name = string.Empty };

和包含null的版本。如果你需要进一步澄清,请告诉我。

using(mockRepository.Playback())
{
    controller = new LockClassPanelController( sessionFactory ); 
    controller.AddLockClass( lockClass.Id, string.Empty );
}

mockRepository.VerifyAll();
