check Property never called

[Ryan]

How can I arrange the mock to assert that a property setter is never called?

I've tried the following: 

Mock.ArrangeSet(() => mockVirtualEntity.EffectiveFrom = DateTime.Now).IgnoreArguments().OccursNever();

I dont care what the value being set is - I just want to make sure the property setter is never called?

Hi Ryan,

Thanks again for your question. Yes it is possible to assert property set for any values. Below is a test that shows how you can arrange property set with Arg.IsAny<T>():

[TestMethod, ExpectedException(typeof(MockAssertionException))]
 public void ShouldThowForOccursNeverForAnyValue()
 {
     var foo = Mock.Create<IFoo>();
     Mock.ArrangeSet(() => foo.EffectiveFrom = Arg.IsAny<DateTime>()).OccursNever();
     foo.EffectiveFrom = DateTime.Now;
     Mock.Assert(foo);
 }

Similarly, it is also possible to assert the specific property for above setup in the following way:

Mock.AssertSet(() => foo.EffectiveFrom = Arg.IsAny<DateTime>());

Moreover, you can also write the first test in this way:

[TestMethod, ExpectedException(typeof(MockAssertionException))]
public void ShouldThowForOccursNeverForAnyValueWithIgnoreArguments()
{
    var foo = Mock.Create<IFoo>();
    Mock.ArrangeSet(() => foo.EffectiveFrom = DateTime.Now).IgnoreArguments().OccursNever();
    foo.EffectiveFrom = DateTime.Now;
    Mock.Assert(foo);
}

Finally, i have attached the test project to let you have a look. Please do feel free to write us back for any other issues.
