Moq to set up a function return based on called times

Question

I need to mock an interface to call to MSMQ, is there a way I can use Moq to simulate real MSMQ scenario that there are 10 messages in the queue, I call mocked function 10 t

Answer 1

I sometimes use a simple counter for such scenarios:

int callCounter = 0;
var mock = new Mock();
mock.Setup(a => a.SomeMethod())
    .Returns(() => 
    {
       if (callCounter++ < 10)
       {
           // do something
       }
       else
       {
           // do something else
       }
    });
