About the Book

A Japanese version is also available

Written by the creator of SpecFlow and the author of The Cucumber for Java Book, this book provides inside information on how to get the most out of the discovery phase of Behaviour Driven Development (BDD). This practical guide demonstrates good collaboration techniques, illustrated by concrete examples.

This book is written for everyone involved in the specification and delivery of software (including product owners, business analysts, developers, and testers). The book starts by explaining the reasons BDD exists in the first place and describes techniques for getting the most out of collaboration between business and delivery team members.

This is the first in the BDD Books series that will guide you through the entire development process, including specific technical practices needed to successfully drive development using collaboratively-authored specifications and living documentation.

There is a Slack channel where topics arising from the BDD Books series can be discussed. First you’ll need to join the Cucumber Community Slack workspace (if you haven’t already). Then join the #bdd-books-discussion channel.
