Which ONE of the following options BEST describes Behavior-Driven Development (BDD)?
A.
Expresses the desired behavior of an application with test cases written in a simple form of natural language that is easy to understand by stakeholders—usually using the Given/When/Then format. Test cases are then automatically translated into executable tests.
B.
Defines test cases at a low level, close to the implementation, using unit test frameworks.
C.
Is primarily focused on non-functional testing techniques to ensure system reliability and performance.
D.
Requires testing to be performed after development is completed to validate software functionality.
Comprehensive and Detailed In-Depth Explanation:BDD emphasizes collaboration between developers, testers, and business stakeholders to define systembehavior in a readable format (A). It typically uses theGiven-When-Thensyntax. Unlike unit testing (B), BDD is at a higher level of abstraction. It does not focus solely on non-functional testing (C) and encourages early testing rather than post-development validation (D).
