positive.code: We're specifically going to write two tests: one testing a passing condition and the second testing a failing condition.  In other words, we will *_want_* the second test to *_fail_*! 
  ====
  
  We're going to start with the test style from our pseudo-code above.  
  
  ----
  test( is, should, msg );
  
negative.code: 
  Of course, once we write the code, we want our test to pass.  This is referred to as 'green' (and if you think most frameworks will show you the result in green, you are correctomundo).  We now have reasonable confidence that our test and our code do what we told them to do.  Just beware - what you told them to do may not be what you actually want them to do.  As you code more, you'll understand this caveat.
  
  Once you have the test and code working as stated, then you can edit your code to be more clear, more concise, more precise, etc.  This is known as "refactoring" the code.  One of the awesome results of TDD, is that you can refactor your code in the confidence that if you break anything _that you've written a test for_, you will be notified of what was broken by a failing test!
  
  ## Implementing a Learners' Level Test Framework
  
  Okay, now for the fun part!
  
  We're going to iterate through writing our own test framework.  It will of course be very simple, but by writing it yourself, you can (a) easily test your own functions without being dependent on a specific test framework, (b) customize it to your hearts extent, and (c) expand it as your needs grow.
