Complain when @Test is applied to an inappropriate method #1074
Description
Overview
When writing tests in Groovy, it's tempting to use def for the test methods, since that is typically the way to go in Groovy. However, for def the compiler produces a method that returns Object.
If this was a method annotated with @Test, it would be silently ignored by JUnit, as it should be a void method. This leads to lots of pulled hairs and other frustrations.

I would like JUnit to shout in my face that I'm using it wrong.
