anchor.diff:  
   If your test calls come _before_ your new `Test` function, then you should have gotten the same "`Test is not defined`" error!  But do not sweat this - just move your test calls after your new function, so that your code looks something like this:
   
  -[code,JavaScript]
  +[code,javascript]
   ----
   // my actual Test class
   var Test = function() {};
  
positive.code: 
  Let me show you a https://developer.mozilla.org/en-US/docs/Web/API/Console#Styling_console_output[cool thing] about most modern browsers, that's particularly relevant for our output:
  
  [code,JavaScript]
  ----
  function test(is, should, msg) {
    if (is === should) {
  
negative.code: 
  Don't forget to run your code and make sure you get your expected output!  For me, that's:
  
  [code,bash]
  ----
  pass
