C#, NUnit: Clear way of testing that ArgumentException has correct ParamName

Question

To test that something throws for example an ArgumentException I can do this:

Assert.Throws<ArgumentException>(() => dog.BarkAt(deafDog));

How can I check that the ParamName is correct in a clear way? And bonus question: Or would you perhaps perhaps recommend not testing this at all?

Answer 1

Found a pretty clear way (but please let me know if anyone have an even better one!)

var e = Assert.Throws<ArgumentException>(() => dog.BarkAt(deafDog));
Assert.That(e.ParamName, Is.EqualTo("otherDog"));

Facepalm...

Answer 2

If you want to do more with the exception than just assert that it is thrown, then Assert.Throws actually returns the exception and you can do this:

var exception = Assert.Throws<ArgumentException>(() => dog.BarkAt(deafDog));
// Assert something else about the exception
