The "Given-When-Then" framework is a structured approach used in software development, particularly in behavior-driven development (BDD). It helps teams define clear scenarios for how a system should behave. The format consists of three parts: Given sets the context or initial state, When describes the action taken by a user, and Then outlines the expected outcome or result. This method promotes better communication among team members, including developers, testers, and stakeholders. By using "Given-When-Then," teams can create understandable specifications that guide development and testing, ensuring that everyone has a shared understanding of the desired functionality.
