In this episode, we explore Behaviour Driven Development (BDD) and how to create executable specifications that capture what we want our systems to do. One of the key ideas that BDD began with was “getting the words right”, could we find better words to describe this approach that would help us to get to the high-value of Test Driven Development (TDD) and help us to better focus on what is important.
How can we characterise TDD vs BDD? Behavior Driven Development is a lot about picking the right words. Dave Farley explores what constitutes good names, giving some examples of both good and bad naming. Naming is important for more than only software testing and the acceptance tests that we write, it also affects the code that we write and its readability and expressibility. He also analyses a test from a popular open-source project and offer his critique of the testing approach.
BDD is a valuable tool in improving our software engineering practices, by creating these executable specifications it can help us improve the quality of our work, and can be an enabling step to help us achieve Continuous Delivery.
