Behavior Driven Development (BDD) is an agile software testing approach that facilitates collaboration between technical and non-technical stakeholders through simple, understandable test cases. The BDD process involves defining scenarios using a 'given-when-then' format, focusing on expected behaviors rather than implementation details. BDD aims to minimize jargon and enhance communication across the organization.
