Description: The ‘Success Criteria’ in Behavior Driven Development (BDD) are the specific conditions that must be met for a test scenario to be considered successful. These criteria are fundamental in clearly defining the expected behavior of a system or application, ensuring that all parties involved, from developers to stakeholders, have a common understanding of what it means for a functionality to be complete and working correctly. Success criteria are typically expressed in simple, accessible language, facilitating communication between technical and non-technical teams. Additionally, these criteria help guide development and testing, providing a clear framework for evaluating whether the software meets the established requirements. Essentially, success criteria are a tool that allows the development team to validate that the final product not only meets technical specifications but also satisfies the end user’s needs. By establishing these criteria from the outset of the development process, ambiguities are minimized, and software quality is improved, resulting in a product that is more aligned with user expectations.
