.net - 在 Rhino Mock 中，我如何 mock 一个属性使其多次成为 “call”？

Question

这应该很容易，所以我一定遗漏了一些东西(很可能这是我第一次使用 Rhino Mock)

我只希望我的代码能够调用 helm.CurrentEnterprise 任意次数，但我却得到:

System.InvalidOperationException occurred
  Message=Previous method 'IHelm.get_CurrentEnterprise();' requires a return value or an exception to throw.
  Source=Rhino.Mocks
  StackTrace:
       at Rhino.Mocks.Impl.RecordMockState.AssertPreviousMethodIsClose()
       at Rhino.Mocks.Impl.RecordMockState.MethodCall(IInvocation invocation, MethodInfo method, Object[] args)
       at Rhino.Mocks.MockRepository.MethodCall(IInvocation invocation, Object proxy, MethodInfo method, Object[] args)

  InnerException:

这是我的代码:

   MockRepository mocks = new MockRepository();
   IHelm helm = mocks.Stub<IHelm>();
   helm.Stub(x => x.CurrentEnterprise).Return(enterprise).Repeat.Any();         

   var a2 = helm.CurrentEnterprise;
   var a2a = helm.CurrentEnterprise; // <- the exception comes from here
   var a2aa = helm.CurrentEnterprise;

尝试生成一个 Mock

MockRepository.GenerateMock<IHelm>()

而不是 stub :

Stub<IHelm>()

The difference between stubs and mocks (Rhino Mocks 在线文档)

A mock is an object that we can set expectations on, and which will verify that the expected actions have indeed occurred. A stub is an object that you use in order to pass to the code under test. You can setup expectations on it, so it would act in certain ways, but those expectations will never be verified. A stub's properties will automatically behave like normal properties, and you can't set expectations on them
