BDD
BDD (Behavior-Driven Development) is a software development methodology that extends Test-Driven Development (TDD) by focusing on collaboration between developers, testers, and business stakeholders. It uses natural language specifications (often in a Given-When-Then format) to define application behavior, ensuring that software meets business requirements and is testable from the start.
Developers should learn BDD when working on projects where clear communication between technical and non-technical teams is critical, such as in agile environments or complex business applications. It helps bridge the gap between business goals and technical implementation, reducing misunderstandings and improving software quality through automated acceptance tests based on shared specifications.
