At the Forge - RSpec for Controllers
RSpec's “outside-in” approach to testing takes a bit of getting used to, but I increasingly have found it to be a method that forces me to think harder about my code, as well as about my testing strategy. That said, I'm not sure if I really have a strong preference for RSpec over similar BDD-style tools, such as Shoulda, which works with Ruby's traditional Test::Unit system. The bottom line is that you should try to include as much automated testing as possible in any software you design—not only because it will benefit your users, but also because it will benefit you as a developer.
The home page for RSpec is rspec.info, and it contains installation and configuration documentation, as well as pointers to other documents.
The Pragmatic Programmers recently released a book called The RSpec Book, written by RSpec maintainer David Chelimsky and many others actively involved in the RSpec community. If you are interested in using RSpec (or its cousin, the BDD tool Cucumber), this book is an excellent starting point.
An RSpec mailing list, which is helpful and friendly, but fairly high volume, is at groups.google.com/group/rspec.
Finally, a good introduction to RSpec and mocking is in The Rails Way, one of my favorite books about Rails, written by Obie Fernandez. This book describes mocking both within the context of RSpec and as a general testing tool when developing Rails applications.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
