BDD (Behavior-Driven Development)

aid: bdd
name: BDD (Behavior-Driven Development)
description: Behavior-Driven Development (BDD) is a software development methodology that combines test-driven development
  with domain-driven design, encouraging collaboration between developers, QA, and business stakeholders through human-readable
  test scenarios. The BDD ecosystem includes frameworks, tools, and data providers that enable teams to write specifications
  in Gherkin syntax (Given-When-Then) and automate those scenarios as executable tests across APIs, UIs, and microservices.
