验证是否通过Moq调用了代表 [英] Verifying a delegate was called with Moq

问题描述

我有一个类，该类通过参数获得一个委托. 此类调用该委托，我想用Moq对它进行单元测试. 我如何验证此方法是否被调用?

i got a class that gets by argument a delegate. This class invokes that delegate, and i want to unit test it with Moq. how do i verify that this method was called ?

示例类:

public delegate void Foo(int number);

public class A
{
   int a = 5;

   public A(Foo myFoo)
   {
      myFoo(a);
   }
}

，我想检查是否调用了Foo. 谢谢.

and I want to check that Foo was called. Thank you.

推荐答案

使用匿名函数怎么办?它可以像内联模拟一样，您不需要模拟框架.

What about using an anonymous function? It can act like an inline mock here, you don't need a mocking framework.

bool isDelegateCalled = false;
var a = new A(a => { isDelegateCalled = true});

//do something
Assert.True(isDelegateCalled);
