   Our primary goal is to write a basic test first.  A basic test looks something like like:
   
  +
   ----
   var is = 'the code to be run';
   var expect = 'the result I expect back';
  
positive.code: 
  My code looks like this now:
  
  [code,JavaScript]
  ----
  // my actual Test object
  var Test = function() {
  
negative.code: 
  First, review our error message.
  
  [code,bash]
  ----
  /*
  Exception: ReferenceError: test is not defined
