RhinoMock帮助:模拟WCF服务

我想用犀牛模型来模拟WCF服务。

假设我有以下服务:

    [OperationContract]
    List<User> SearchUsers(UserSearchFilter filter);

将此服务与Visual Studio一起添加将生成代理,并且该代理具有如下接口:

 public interface ResourceService {

    System.IAsyncResult BeginSearchUsers(UserSearchFilter filter, System.AsyncCallback callback, object asyncState);

    ObservableCollection<User> EndSearchUsers(System.IAsyncResult result);
}

然后我创建一个使用此服务的视图模型,如下所示:

        private ResourceService service;
    public ViewModelBase(ResourceService serv)
    {
        service = serv;
        var filter = new UserSearchFilter();
        service.BeginSearchUsers(filter, a =>
        {
            this.Users = service.EndSearchUsers(a); 
        }, null);
    }

然后问题来了。我如何用犀牛模型来模拟这项服务?

       [TestMethod]
    public void UserGetsPopulatedOnCreationOfViewModel()
    {
        // Is stub the right thing to use?
        ResourceService serv = MockRepository.GenerateStub<ResourceService>();

        // Do some setup... Don't know how?
        var vm = new ViewModel(serv);

        Assert.IsTrue(vm.Users.Count > 0);
    }

如果有人能帮助我正确使用犀牛模型,我真的很高兴

(注意:我正在使用Silverlight,但我认为这不会改变犀牛模型的使用方式)

谢谢!
