title: Test if a class has an attribute?
body: <p>I'm trying to do a little Test-First development, and I'm trying to verify that my classes are marked with an attribute:</p>
  
  <pre><code>[SubControllerActionToViewDataAttribute]
  public class ScheduleController : Controller
  </code></pre>
  
  <p>How do I unit test that the class has that attribute assigned to it?</p>
