Almost half of all software projects fail to deliver on key requirements. Behavior-Driven Development (BDD) reduces these costly failures by building a shared understanding of how an application should work. Behavior Driven Development in Action, Second Edition teaches communication skills, collaborative practices, and automation tools that ensure everyone from developers to non-technical stakeholders are in agreement on the goals of a project. Revised and expanded in a second edition, the book contains new techniques for incorporating BDD into large-scale development practices such as Agile and DevOps, as well as updating examples for the latest versions of Java.

About the Technology
You can’t write good software if you don’t understand what it’s supposed to do. Behavior-Driven Development (BDD) encourages developers, quality teams, and non-technical stakeholders to collaborate, using conversation and concrete examples to make sure everyone agrees how an application should work and what features really matter. With a body of best practices and sophisticated tools for requirement analysis and test automation, BDD has become a mainstream practice for keeping projects on track and avoiding cancellation.About the book
Revised and upgraded with the latest tools and practices, Behaviour Driven Development in Action, Second Edition teaches you how to integrate BDD into your software development process. The book starts with the communication skills that are the core of good BDD, showing how a successful requirements analysis will reduce waste and make sure you are developing features in line with business goals. Once you’ve established this collaborative structure, you’ll learn how to use automated acceptance criteria to guide and report on the development process. Alongside learning to apply BDD principles at the coding level for more maintainable code, this new edition is expanded with coverage of working with BDD in large-scale Agile systems and as part of DevOps practices.What's inside
