Test-first programming with Ruby

Pat Eyler (pat.eyler@gmail.com), Freelance Writer, Seattle Ruby Brigade
Pat Eyler is a co-founder of the Seattle Ruby Brigade and has been an active member of the Ruby community for nearly five years. He currently maintains the r43 library. He has written about free software, Linux, Ruby, and networking for several print- and Web-based publishers.

Summary:  This tutorial looks at building Ruby applications following test-first principles. It starts with an overview of the Test::Unit library that ships with Ruby, then moves on to writing tests from a specification and writing code to fulfill those tests. It touches on tools like ZenTest and unit_diff, as well as on the process of refactoring, and is built around a single programming example.

Summary

In this tutorial, you started building a Ruby library test first. In addition to writing tests and code, you learned to apply these principles to refactoring to improve the code you'd written. You also learned about the Test::Unit library, ZenTest, unit_diff, and mock objects.


By applying these ideas in your day-to-day Ruby programming, you'll be able to write code faster. Your code will also be better tested, more robust, and easier to debug, optimize, and extend.
