In this brief chapter, we will take a look at the tools available and conventions employed in the Ruby world for keeping one’s code in order. We’ll kick off with a section devoted to rake. Understanding the mechanics of this task-oriented, make-like tool can really save you time in the long run—especially where common housekeeping tasks are concerned. From here we’ll move on to a section on unit testing, where we’ll look at some step-by-step examples and make the case that such testing is about as simple asit can be in Ruby. Finally, we’ll cover the documentation idioms and the magic of rdoc.

As the last chapter of the book, this one’s going to be a little different. I will present a very brief summary of some of the developments coming down the Ruby pipe. I feel this is important because in order to make a wholesale leap to a new programming language (as you may be), you have to be satisfied that the horse you’re backing “has legs”—that it isn’t a passing fad. Alternatively, if you are already sold on Ruby’s credibility, I hope you will still find what is discussed here of some general interest.
