c# - 我可以在 Rhino Mocked 对象上定义方法的实现吗？

Question

使用 Rhino.Mocks，一旦我模拟了一个界面，我就可以:

• 为模拟对象上的非 void 方法设置“返回”值
• 检查某些方法的调用方式和值

但是，是否可以有选择地为模拟对象上的方法定义一个实现？

理想情况下我想这样做(RhinoImplement 是我希望存在的 Rhino 扩展!):

var messages = new List<IMessage>();

IBus bus = MockRepository.GenerateMock<IBus>();

bus.RhinoImplement(b => b.Send(Arg<IMessage>.Is.Anything), imess => messages.Add(imess));

//now run your test on the Class that uses IBus

//now, I can inspect my local (List<IMessage>)messages collection

用答案更新

感谢帕特里克在下面的回答，实现上述目标的正确代码是:

var messages = new List<IMessage>();

IBus bus = MockRepository.GenerateMock<IBus>();

bus
    .Expect(b => b.Send(Arg<IMessage>.Is.Anything))
    .WhenCalled(invocation => messages.Add((IMessage)invocation.Arguments[0]))
    .Repeat.Any() //the repeat part is because that method might be called multiple times

//now run your test on the Class that uses IBus

//now, I can inspect my local (List<IMessage>)messages collection

Answer 1

使用“WhenCalled”方法:
