Mocking a private property setter in your Unit Tests using Moq

I recently encountered a requirement whereby I had to set the value for a property that had a private setter in my Mock objects.

Fortunately, Moq has a solution for this!

You can use the .SetupGet method to set a private property as follows:

myMock.SetupGet(m => m.MyPrivateSetter).Returns(myValue);
