Deliver software that does what it’s supposed to do! Behavior-Driven Development guides your software projects to success with collaboration, communication techniques, and concrete requirements you can turn into automated tests.

In BDD in Action, Second Edition you’ll learn how to:

Implement and improve BDD practices
Prioritize features from business goals
Facilitate an example mapping session
Write automated acceptance tests
Scale up your automated acceptance tests
Deliver accurate reporting and documentation

Around half of all software projects fail to deliver on requirements. Behavior-Driven Development (BDD) helps make sure that yours isn’t one of them. Behavior-Driven Development in Action, Second Edition teaches you how to ensure that everyone involved in a software project—from developers to non-technical stakeholders—are in agreement on goals and objectives. It lays out the communication skills, collaborative practices, and useful automation tools that will let you seamlessly succeed with BDD. Now in its second edition, this revised bestseller has been extensively updated with new techniques for incorporating BDD into large-scale and enterprise development practices such as Agile and DevOps.

about the technology

Behavior-Driven Development is a collaborative software design technique that organizes examples of an application’s desired behavior into a concrete, testable specification. Because the BDD process gathers input from all areas of an organization, it maximizes the likelihood your software will satisfy both end users and business stakeholders. The established collaboration practices and automation strategies in this book will help you maximize the benefits of BDD for your dev team and your business clients.

about the book

John and Jan describe valuable techniques with their customary clarity and detail. I found myself nodding along, as well as having a couple of ‘Aha!’ moments myself. I am delighted that BDD still has this much traction and interest nearly 20 years on, and I am grateful to John and Jan for producing this new edition of such a comprehensive resource.

From the Foreword by Daniel Terhorst-North, practitioner consultant

If understanding how your own software should work is ever a hard question, you should read this book.

An approachable and accessible introduction. I recommend it to developers who want to quickly adopt BDD for their projects.
