Techopedia Explains Behavior Driven Development

BDD provides a formal application building framework that combines agile software development (ASD), test driven development (TDD) and other principles to build software products. BDD works by associating business outcome as a “story” or specification that defines its requirements, business benefits and common testing methodology used to ascertain the completion of a software unit.

BDD distributes stakeholders between two distinct classes, as follows:

  • Core stakeholders: Focus on business objectives, outcomes and application behavior
  • Incidental stakeholders: Functional and non-functional people work to provide the desired application behavior and outcome
