如何在没有接口的情况下模拟类? [英] How do I mock a class without an interface?

问题描述

我正在Windows 7中使用C#在.NET 4.0上工作.

I am working on .NET 4.0 using C# in Windows 7.

我想使用模拟测试某些方法之间的通信.唯一的问题是我想在不实现接口的情况下执行此操作.那可能吗?

I want to test the communication between some methods using mock. The only problem is that I want to do it without implementing an interface. Is that possible?

我刚刚阅读了很多关于模拟对象的主题和一些教程，但是它们全部都用于模拟接口，而不是类.我尝试使用Rhino和Moq框架.

I just read a lot of topics and some tutorials about mock objects, but all of them used to mock interfaces, and not the classes. I tried to use Rhino and Moq frameworks.

推荐答案

只需将您需要伪造的任何方法标记为virtual(而不是私有).然后，您将能够创建可以覆盖该方法的伪造品.

Simply mark any method you need to fake as virtual (and not private). Then you will be able to create a fake that can override the method.

如果使用new Mock<Type>并且没有无参数构造函数，则可以将参数作为上述调用的参数传递，因为它采用的类型为param Objects

If you use new Mock<Type> and you don't have a parameterless constructor then you can pass the parameters as the arguments of the above call as it takes a type of param Objects
