Using Moq to Mock a Func<> constructor parameter and Verify it was called twice

Question

Taken the question from this article (How to moq a Func) and adapted it as the answer is not correct.

public class FooBar
{
    private Func

        

Answer 1

I don't think it is necessary to use a mock for the Func.

You can simply create an ordinary Func yourself that returns a mock of IFooBarProxy:

int numberOfCalls = 0;
Func func = () => { ++numberOfCalls;
                                  return new Mock(); };

var sut = new FooBar(func);

sut.Process();

Assert.Equal(2, numberOfCalls);
