Description: Behavior Driven Development (BDD) is an agile software development methodology that promotes collaboration between developers, testers (QA), and non-technical stakeholders, such as business representatives. Its focus is on defining expected behaviors of the software through concrete and understandable examples for all involved. Instead of solely focusing on technical implementation, BDD seeks to understand and document how the system should behave from the end user’s perspective. This is achieved by creating specifications that are readable by both technical and non-technical individuals, using a common language that facilitates communication. BDD tools, such as Cucumber or SpecFlow, allow for automated tests to be written based on these specifications, ensuring that the developed software meets the defined requirements. This methodology not only improves software quality but also fosters a collaborative work environment where all team members can contribute to defining requirements and validating the final product. In summary, Behavior Driven Development is a practice that integrates development, testing, and business participation in a continuous cycle of improvement and adaptation, aligning the final product with user expectations.
