Behavior Driven Development / Acceptance Test-Driven Development: Better Software through Collaboration

Built-in quality allows quicker delivery of business value. A key practice to realize built-In quality is using Behavior Driven Development (BDD) / Acceptance Test-Driven Development (ATDD). This workshop describes how the Triad (customer, tester, and developer perspectives) collaborates to create a shared understanding of the desired behavior of an application. It shows how to define scenarios which specify that behavior and use these scenarios as a communication and verification tool. Applying BDD/ATDD helps to decrease rework, raise customer satisfaction, and promotes trust.


This immersive workshop uses your team’s actual stories for the exercises during the interactive lecture and individual team sessions. For maximum effectiveness, the entire team (product owner, scrum master, developers, testers, business analysts, subject matter experts) should attend the training together. One of the outcomes will be scenarios that are ready for implementation.


By the end of this workshop, participants will know and have experienced:

  • The benefits of Behavior Driven Development / Acceptance Test-Driven Development
  • Decreasing misunderstanding by forming a shared customer / business domain language
  • Specifying behavior in stories using scenarios to create a shared understanding
  • Turning scenarios into acceptance tests
  • Using scenarios as a communication vehicle
  • Understanding scenarios in their context
  • Transitioning to BDD/ATDD
  • How BDD/ATDD embodies Built-In Quality and Shift Left
