The Cucumber Book is an excellent reference for Cucumber in Ruby, and provides a good introduction to BDD practices. But Cucumber is not the only BDD tool, and BDD is not about using a particular tool. BDD in Action is broader and covers more practices and tools, from high-level requirements analysis, through automated acceptance criteria (with examples and tools in several languages, such as
Java, .Net and Python), and down to the
unit testing level (again, with tools and examples in several languages, including Java, .Net, Javascript and so on). BDD in Action also covers the
philosophy and conceptual approach behind BDD in detail, which is applicable for any language or platform.
