How do I mock an out parameter with Moq?

Question

I have a class that I am testing. This class uses takes in an interface as a constructor parameter. This interface has a method that has an out parameter.

What I want to do is mock this method so that the out parameter is always a particular value.

How can this be done?

To do this just create a local with the desired value and use that in the out position.

int theValue = 42;
Mock<ITarget> target = ...;
target.Setup(x => x.TheMethod(out theValue));
