#148 - Behavior-Driven Development (BDD) Essentials - Jan Molak & John Ferguson Smart

“BDD is about helping you collaborate with the different parties involved in software delivery to understand what’s actually required of your system, why you need to deliver it, and then find the best possible way to automate your requirements."

John Smart and Jan Molak are the co-authors of “BDD in Action: Second Edition”. In this episode, we discussed in-depth behavior-driven development (BDD) and its essentials. Jan and John first began by introducing what BDD is, the benefits of using BDD, and the Gherkin language with its given-when-then syntax. They gave advice on how to introduce and apply BDD, especially for legacy software, and how to manage the BDD specifications effectively. Jan and John then shared several BDD techniques, such as feature mapping, example mapping, impact mapping; and went deep into the screenplay pattern and the Serenity projects they both create to implement screenplay pattern. Towards the end, Jan and John shared their insights on which testing layers we should apply BDD and some anti-patterns we should avoid.
