Rhino Mocks DynamicMultiMock - 在附加接口上设置期望值和返回值

Question

我正在创建一个 DynamicMultiMock 如下：

this.serviceClient = this.mocks.DynamicMultiMock<ISlippyPlateProcedureService>(typeof(ICommunicationObject));

然后设置如下期望：

Expect.Call(((ICommunicationObject)this.serviceClient).State).Return(CommunicationState.Faulted);

当我执行测试时，Rhino Mocks 会报告：
重播期望：ICommunicationObject.get_State();
动态模拟：意外的方法调用被忽略：ICommunicationObject.get_State();

我是否正确设置了这个期望，还是有其他方法？

编辑以包含完整的测试代码：

        Expect.Call(this.syncContextContainer.SynchronizationContext).Return(new SlippyPlateProcedureSynchronizationContextMock());
        Expect.Call(this.clientFactory.CreateServiceClient(null)).IgnoreArguments().Return(this.serviceClient);
        Expect.Call(((ICommunicationObject)this.serviceClient).State).Return(CommunicationState.Faulted);
        Expect.Call(() => this.serviceClient.IsAlive());
        this.mocks.ReplayAll();
        SlippyPlateProcedureClient client = new SlippyPlateProcedureClient(
            this.syncContextContainer, this.clientFactory, this.container);
        PrivateObject privateObject = new PrivateObject(client);
        SlippyPlateProcedureClient_Accessor target = new SlippyPlateProcedureClient_Accessor(privateObject);

        target.CheckServerConnectivity();

        this.mocks.VerifyAll();

谢谢

如果不查看您的生产代码，真的很难判断出了什么问题。以下测试通过：

public interface IA
    {
        int A(int a);
    }

    public interface IB
    {
        int B(int b);
    }

    [Test]
    public void Multimocks()
    {
        MockRepository mocks = new MockRepository();
        IA mymock = mocks.DynamicMultiMock<IA>(typeof (IB));
        Expect.Call(mymock.A(1)).Return(2);
        Expect.Call(((IB)mymock).B(3)).Return(4);
        mocks.ReplayAll();

        Assert.AreEqual(2, mymock.A(1));
        Assert.AreEqual(4, ((IB)mymock).B(3));
    }

这意味着 multimocks 可以正常工作。你确定你不止一次打电话给 State 吗？尝试将您的模拟更改为 StrictMocks（当不期望调用时您会得到一个异常），所以：

this.serviceClient = this.mocks.StrictMultiMock<ISlippyPlateProcedureService>(typeof(ICommunicationObject));

并让属性被多次读取：

Expect.Call(((ICommunicationObject)this.serviceClient).State).Return(CommunicationState.Faulted).Repeat.Any();
