Question

我在这种情况下嘲笑：

class A
{
    public IB B {get; set;}
}

interface IB
{
  //methods
}

class B : IB
{
  //IB methods
}

public SimpleMockTest()
{
   var mockIB = new Mock<IB>();
   var a = new A{B=mockIB.Object};
   //do stuff with A, then verify methods on IB were called       
}

public TheKindOfTestIWantToDo()
{
   var actualB = new B();
   var mockIB = new Mock<IB>();
   var splitter = new Splitter<IB>(actualB, mockIB.Object); //I need something like this
   var a = new A{B=splitter};
   //do stuff with A, methods invoked on splitter IB get passed to both supplied instances
   //of IB (actualB, and the mockIB). Allowing me to verify the calls as well as have the methods invoked on the actual B object.
   //OR:
   var mockIB2 = new Mock<IB>(actualB); //behaviour is dictated by the actual, but allows verification
   var a2 = new A{B=mockIB2.Object};
}

所以我在某种代理工厂之后，通用支持接口并在多个接口上调用相同的方法。当然，当一个方法返回一个值时，每个方法都需要返回相同的值，或者一个方法需要预先确定。

我希望在测试期间有效地窥探接口调用，但不会将模拟作为行的结尾。

如果它有任何不同，我会使用Moq。

据我所知，actualB上的所有方法都无法做到这一点。

我想你想要这样的东西：

public TheKindOfTestIWantToDo()
{
   var actualB = new B();
   var mockIB = new Mock<IB>();
   mockIB.Setup(b => b.Foo()).Returns(() => actualB.Foo())
   var a = new A { B = mockIB };
   //do stuff with A, methods invoked on splitter IB get passed to both supplied instances
   //of IB (actualB, and the mockIB). Allowing me to verify the calls as well as have the methods invoked on the actual B object.
}

但您应该重新考虑您的单元测试策略。 A的行为应该是可测试的，而不依赖于B的行为。尝试让mockIB返回特定值，然后为B编写一组不同的测试。
