ViewResult.ViewName returns empty on UnitTest

I see there are a lot of questions about this same topic, but since they are all from 2008 - 2011, I'd say there's a chance this might be an official way to do this without external libraries/extensions.

So the issue is when running my test cases, the ViewName comes empty:

// Act
ViewResult result = await Controller.Create(model) as ViewResult;

// Assert
Assert.AreEqual("Create", result.ViewName);

Any official way to deal with this? or maybe I can test some other property?
