BDD made easy

Behavior-driven development, or BDD, has attracted a lot of attention via RSpec in the Ruby community, but BDD's roots stem from JBehave, a Java based framework modeled off of the xUnit paradigm. But JBehave isn't the only framework available for Java developers– with the advent of Groovy, new options are available for embracing BDD in the spirit of RSpec's innovative behavior based DSL.

In this session, we'll look at what BDD is, how it is an evolutionary result of Test Driven Development, and how it shifts the traditional testing vocabulary from being test-based to behavior-based. You'll also see that this subtle shift in thinking facilitates writing behavior classes first, which is the ultimate goal of TDD style thinking in the first place.

We'll examine RSpec in an effort to understand why BDD is catching on quickly in the Ruby community and then we'll study JBehave's framework for literate programming with expectations along with its Story framework for building executable user stories. With a solid understanding of JBehave, we'll probe some of the more innovative features of Groovy (including building DSLs) which have yielded the easyb BDD framework.
