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.

Foreword by Daniel Terhorst-North.

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

In BDD in Action, Second Edition, you’ll learn to seamlessly integrate BDD into your existing development process. This thoroughly revised new edition now shows how to integrate BDD with DevOps and large-scale Agile systems. Practical examples introduce cross-functional team communication skills, leading a successful requirements analysis, and how to set up automated acceptance criteria.

What’s Inside

• How BDD positively affects teamwork, dynamics, and collaboration with stakeholders
• Help teams discover and analyze requirements, uncover assumptions, and reduce risks
• Make acceptance, integration, and unit testing more effective
• Automate reporting and living documentation to improve transparency

About the Reader

For all development teams. No experience with BDD required. Examples in Java, JavaScript, and TypeScript can be easily expressed in your chosen language.
