Moq a function with 5+ parameters and access invocation arguments.
- by beerncircus
I have a function I want to Moq. The problem is that it takes 5 parameters. The framework only contains Action<T1,T2,T3,T4> and Moq's generic CallBack() only overloads Action and the four generic versions. Is there an elegant workaround for this?
This is what I want to do:
public class Filter : IFilter
{
public int Filter(int i1, int i2, int i3, int i4, int i5){return 0;}
}
//Moq code:
var mocker = new Mock<IFilter>();
mocker.Setup(x => x.Filter(
It.IsAny<int>(),
It.IsAny<int>(),
It.IsAny<int>(),
It.IsAny<int>(),
It.IsAny<int>(),
It.IsAny<int>())
.Callback
(
(int i1, int i2, int i3, int i4, int i5) => i1 * 2
);
Moq doesn't allow this because there is no generic Action that takes 5+ parameters. I've resorted to making my own stub. Obviously, it would be better to use Moq with all of its verifications, etc.
