BDD, also known as Behavior Driven Development, is a software development methodology focused on collaboration and alignment between different teams involved in the software development process such as developers, testers, and stakeholders. It is an extension of Test Driven Development (TDD) approach.
In BDD, the behavior of the software is specified in a manner that is easily understandable by non-technical stakeholders and is based on the desired outcomes or behaviors of the system. It promotes a shared understanding of the system's behavior by using a natural language syntax called Gherkin, which allows the description of system behaviors in a structured, human-readable format.
This methodology emphasizes the importance of defining scenarios and examples based on different behaviors or features of the system. These scenarios serve as executable specifications, meaning they can be directly executed as tests to validate whether the software meets the desired behavior.
BDD aims to foster collaboration between stakeholders by providing a common language that can bridge the gap between technical and non-technical individuals. It encourages active participation from stakeholders during the entire development process, ensuring that the behavior of the software aligns with the business requirements.
Overall, BDD promotes a user-centric approach to software development, where the focus is on delivering software that meets the expectations and needs of the end-users, with clear communication and shared understanding among all parties involved.
