What is BDD 2.0 (SDD)?

Behavior-Driven Development (BDD) is an Agile software approach that prioritizes clear communication and collaboration among stakeholders by focusing on user-centric stories to define software requirements, drawing inspiration from methodologies like Test-Driven Development (TDD) and Acceptance Test-Driven Development (ATDD). It aims to align development teams with stakeholder expectations and produce living documentation that evolves with the product. However, practical challenges such as reliance on technical scripting tools like Selenium, the complexity of Gherkin syntax, and the need for technical expertise pose issues, leading to the development of BDD 2.0 or Specification-Driven Development (SDD). SDD addresses these limitations by allowing specifications to be directly executable in plain language, enhancing participation from non-technical stakeholders and streamlining the testing process. Tools like testRigor exemplify SDD by enabling stakeholders to write executable specifications using AI-generated, plain English commands, thus minimizing the need for technical coding and maintenance. This approach facilitates more efficient test automation, enhances communication, and ensures software meets user expectations, overcoming the typical obstacles associated with traditional BDD.
