Behavior Driven Development (BDD)

What is Behavior Driven Development (BDD)?

Behavior-driven development (BDD) is a software development approach that focuses on defining the behavior of an application or system through the use of examples. These examples, called "acceptance criteria," are used to define the expected behavior of the system in different scenarios, and they serve as a basis for writing automated tests that can be used to validate the system's behavior.

The goal of BDD is to improve communication and collaboration among developers, testers, and other stakeholders by providing a common language and a shared understanding of the system's behavior. It helps to ensure that the system is being developed in a way that meets the needs and expectations of all stakeholders, and that it is tested and validated in a way that is consistent with those expectations.

BDD typically involves the use of specialized software tools and frameworks, such as Cucumber or JBehave, that can be used to define and execute acceptance criteria and automated tests. It is often used in combination with agile software development methodologies, such as Scrum or Lean, to enable rapid, iterative development and testing of software systems.
