Behavior-driven development (BDD) is a collaborative approach to software development that emphasizes teamwork, automation, and continuous improvement. It aims to close the communication gap between technical and non-technical stakeholders by using plain-language natural language requirements. BDD encourages testing software behavior, particularly functionality that users can see, and organizing the testing and development process into smaller, more manageable chunks. The approach promotes a user-centric focus on providing value to the user, collaboration among team members, and automation of acceptance testing. By adopting BDD, teams can improve product quality, reduce defects, shorten time to market, and efficiently use resources, ultimately leading to increased return on investment (ROI).
