The RSpec Book--New from Pragmatic Bookshelf
Behaviour Driven Development with RSpec, Cucumber, and Friends

Raleigh, NC--Behaviour-Driven Development (BDD) gives you the best of Test Driven Development,
Domain Driven Design, and Acceptance Test Driven Planning techniques, so you can create better
software with self-documenting, executable tests that bring users and developers together with a
common language.

Get the most out of Behaviour-Driven Development in Ruby with "The RSpec Book: Behaviour-Driven
Development with RSpec, Cucumber, and Friends" (Pragmatic Bookshelf, $38.95), written by the lead
developer of RSpec, David Chelimsky.

You'll get started right away with RSpec 2 and Cucumber by developing a simple game, using Cucumber
to express high-level requirements in language your customer understands, and RSpec to express more
granular requirements that focus on the behavior of individual objects in the system. You'll learn
how to use test doubles (mocks and stubs) to control the environment and focus the RSpec examples
on one object at a time, and how to customize RSpec to "speak" in the language of your domain.

You'll develop Rails 3 applications and use companion tools such as Webrat and Selenium to express
requirements for web applications both in memory and in the browser. And you'll learn to specify
Rails views, controllers, and models, each in complete isolation from the other.

The authors explain why this style of writing code is significantly better than traditional
attempts: "The problem with testing an object's internal structure is that we're testing what an
object is instead of what it does. What an object does is significantly more important. BDD puts
the focus on behavior instead of structure, and it does so at every level of development. Whether
we're talking about an object calculating the distance between two cities, another object
delegating a search off to a third-party service, or a user-facing screen providing feedback when
we provide invalid input, it's all behavior!"

Whether you're developing applications, frameworks, or the libraries that power them, "The RSpec
Book" will help you write better code, better tests, and deliver better software to happier users.

Available in epub, mobi, PDF direct from the publisher and in paperback from fine bookstores
worldwide.

About the Authors
David Chelimsky is the lead developer/maintainer of RSpec, and has contributed to several other
open source projects including Cucumber, Aruba, and Rails. He has been developing software for over
a decade, including three years training and mentoring agile teams at Object Mentor. He is
currently a Senior Software Engineer at DRW Trading Group in Chicago, IL. In his spare time, David
likes to play guitar, travel, and speak something resembling Portuguese.

Dave Astels is the Director of Technology at ChannelFireball.com and has been involved with
software and computing for over 25 years, recently having spent several years working exclusively

Bryan Helmkamp maintains Webrat, a Ruby library to implement acceptance tests for web applications
in an expressive and maintainable way, and is an active participant in the New York City Ruby
community. Bryan is the CTO of Efficiency 2.0, a startup that helps people understand and reduce
their energy use.

Dan North writes software and coaches teams and organizations in agile and lean methods. He
believes that most problems that teams face are about communication and understanding, which is why
he puts so much emphasis on "getting the words right." In 2003-4 this led him to develop the ideas
that would become Behaviour-Driven Development. He is delighted by the community that has grown up
around RSpec and Cucumber, and especially the enthusiasm and dedication of their core contributors.
Dan is currently a Senior Software Engineer at DRW Trading Group in London, where he gets to
actually code again!

this book he was the Chief Scientist of BEKK Consulting in Oslo. In 2003, after seven years of
