Moq - How to verify that a property value is set via the setter

Question

Consider this class:

public class Content
{      
   public virtual bool IsCheckedOut {get; private set;}
   public virtual void CheckOut()
   {
      IsChec         


        

Answer 1

The following should work. Configure your mock object as:

var mock=new Mock();
mock.SetupSet(content => content.IsCheckedOut=It.IsAny()).Verifiable();

And after the test code:

mock.VerifySet(content => content.IsCheckedOut=It.IsAny());

I haven't tested it anyway, so please tell me if it works for you.

EDIT. Indeed, this will not work since the setter for IsCheckedOut is false.

Anyway, now I see that you never set the value of IsCheckedOut at class construction time. It would be a good idea to add the following to the Content class:

public Content()
{
    IsCheckedOut=false;
}
