What is Behavior-Driven Development (BDD)?
Behavior-Driven Development extends test-driven practices by expressing requirements as concrete, plain-language scenarios—typically in Given-When-Then form—that everyone from product to QA can read and agree on. These scenarios become executable specifications, tying acceptance criteria directly to automated tests. BDD improves shared understanding and reduces the gap between what was asked for and what was built. Because BDD scenarios describe end-user behavior, they map naturally onto recorded user flows and readable end-to-end tests that serve as living documentation.
