如何在Rhino Mock'd对象中调用回调？

Question

I know there has to be a way to do this...I'm just new to RhinoMocking.

Essentially, I have the following class:

class B
{
     private object _dependency;

     public B(object dependency)
     {
          _dependency = dependency;
     }

     public void Method()
     {
         dependency.DependencyMethod(delegate(){ Method2(); });
     }

     private void Method2()
     {
         // do stuff
     }
}

I'm passing a rhino mocked, interface as a dependency in my test. I want to test Method2 in my test...but its private, so the only way to get at it is by looking at the argument to DependencyMethod. How do I do that? :P

Thanks!

Answer 1

One test should determine that Method() passes a delegate. Another test should determine that the real dependency calls the delegate.

To to verify that Method() passes the delegate to Method2 you need to make the delegate visible. Perhaps you can pass this as a dependency so that in another test you can verify that Method() passes you the delegate that you passed in.

 private object _dependency;
 private delegate_type _delegate;

 public B(object dependency, delegate_type theDelegate)
 {
      _dependency = dependency;
      _delegate= theDelegate;
 }

 public B(object dependency) : this(dependency, delegate(){ Method2(); }) {}

 public void Method()
 {
     dependency.DependencyMethod(theDelegate);
 }

因此，在深入研究之后，我认为最好的方法是在我的模拟游戏中使用GetArgumentsForCallsMadeOn，以这种方式获取委托，然后调用它。
