MXUnit ExpectedException

I'm glad to see the next minor release of MXUnit :) I'm even happier to see ExpectedException make it into the release. I'd been doing a lot of development in Java and using the latest JUnit and the expected exception annotation was so nice. When I went back to writing test cases for Fusebox I found myself avoiding writing tests that would throw errors (like testing bad paths for Fusebox parsed files). Well long story short I found myself one night debugging something in Fusebox only to find Fusebox should have been throwing an error. Since I never tested for it I never caught that Fusebox was not throwing an error. That motivated me enough to spend the 30 or so minutes it took me to write a couple test cases and add the functionality to MXUnit.

So the old way to test for an error was something like this:

      <cffunction name="ensure_error_on_load_extentions_with_bad_path">
           <cftry>
               <cfset extManager.loadExtensions(getDirectoryFromPath(getCurrentTemplatePath()) & '/notthere') />              
               <cfset Fail("Last line should have thrown an error") />
               <cfcatch type="mxunit.exception.AssertionFailedError">
                   <cfrethrow>
               </cfcatch>
               <cfcatch type="fusebox.BadDirectory" />
               <cfcatch type="any">
                   <cfset debug(cfcatch) />
                   <cfset fail("Bad Error")>
               </cfcatch>
           </cftry>
       </cffunction>

Now all we have to do is this:

       <cffunction name="ensure_error_on_load_extentions_with_bad_path" mxunit:expectedException="fusebox.BadDirectory">
               <cfset extManager.loadExtensions(getDirectoryFromPath(getCurrentTemplatePath()) & '/notthere') />              
       </cffunction>

I love the feature, and I hope others enjoy it too.
