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 times and I can get a pre-defined object, on 11th time I should get a different return value (e.g. null)?
Moq now has an extension method called
SetupSequence() in the
Moq namespace which means you can define a distinct return value for each specific call.
The general idea is that that you just chain the return values you need. In the example bellow the first call will return Joe and the second call will return Jane:
customerService .SetupSequence(s => s.GetCustomerName(It.IsAny<int>())) .Returns("Joe") //first call .Returns("Jane"); //second call
