What is BDD (Behavioural-Driven Dvelopment)?

In Brief,

Behavior-Driven Development (BDD) is a software development methodology that focuses on the behavior of the system being developed. It is an extension of Test-Driven Development (TDD) and emphasizes collaboration between developers, quality assurance (QA) team members, and stakeholders in order to understand the system's behavior. BDD uses natural language constructs, such as user stories, to describe the desired behavior of the system. This allows for a shared understanding of the system's behavior among all team members, and helps to ensure that the system is developed to meet the needs of its users. BDD also uses automated testing tools, such as Cucumber, to test the system's behavior, providing fast and accurate feedback on the system's behavior during development.
