Synopses & Reviews
Continuous Testing (CT) is a developer practice that shortens the feedback loops established by test-driven development and continuous integration. Building on techniques used by Agile software development practitioners, Continuous Testing with Ruby shows you how to get instant feedback about both the quality of your code, and the quality of your tests.
Automated testing is an increasingly common practice in the software development industry. However, many companies struggle to gain all the benefits of automated testing, due to poorly written or incomplete tests. Continuous Testing with Ruby shows how these companies can get the most value out of their existing tests. It also helps you improve the quality of the new tests you write, by giving you instant feedback about problem areas, and creating a visceral feedback loop for test quality that you can actually feel as you work.
Just as continuous integration and test-driven development have changed the definition of software development in the last ten years, Continuous Testing is poised to become a standard practice for development teams in the next decade.'
"Some authors would be satisfied with just writing the definitive guide for a technology. These folks go a step further, and show you insider tips that will keep your tests clean and maintainable."—Ian Dees, Software Engineer
"The second generation of tools for the XP generation explained by their creators and maintainers. Awesome, a must read."—Marcus Ahvne, software developer, Valtech
"The RSpec Book teaches you much more than how to use RSpecs features; it teaches you how to write code the way the RSpec team does: patiently, and with great precision and clarity. There is something here for everyone: beginners are given plenty of gentle attention but there is some real meat for the more experienced reader to chew on, too."—Matt Wynn, independent programmer and coach
Concerned with writing software that matters and filled with tutorials and practical examples, this approach to agile software development takes cues from Test Driven Development, Domain Driven Design, and Acceptance Test Driven Planning.
Behaviour Driven Development is about writing software that matters. It is an approach to agile software development that takes cues from Test Driven Development, Domain Driven Design, and Acceptance Test Driven Planning.
RSpec and Cucumber are the leading Behaviour Driven Development tools in Ruby. RSpec supports Test Driven Development in Ruby through the BDD lens, keeping your focus on design and documentation while also supporting thorough testing and quick fault isolation. Cucumber, RSpec's steadfast companion, supports Acceptance Test Driven Planning with business-facing, executable requirements documentation that helps to ensure that you are writing relevant software targeted at real business needs.
The RSpec Book will introduce you to RSpec, Cucumber, and a number of other tools that make up the Ruby BDD family. Replete with tutorials and practical examples, the RSpec Book will help you get your BDD on, taking you from executable requirements to working software that is clean, well tested, well documented, flexible and highly maintainable.
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 BDD in Ruby with The RSpec Book, 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.
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.

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!
