   So, let's tell it to compare an `is` with a `should` and log the result. 
   
  -[code,javascript]
  +[source,javascript]
   ----
   function test(is, should) {
     console.log (is === should);

  If your code doesn't work and you can't figure out the next step based on the `Test.yo` code, then go ahead and review my final, working code:
  
  [code,javascript]
  ----
  // my actual Test class
  var Test = function() {};
  
negative.code: 
  Don't forget to run your code and make sure you get your expected output!  For me, that's:
  
  [source,bash]
  ----
  pass
