BehaviourDrivenDevelopment - Behaviour-Driven Development
Behaviour-Driven Development (BDD) is an evolution in the thinking behind TestDrivenDevelopment and AcceptanceTestDrivenPlanning.
It brings together strands from TestDrivenDevelopment and DomainDrivenDesign into an integrated whole, making the relationship between these two powerful approaches to software development more evident.
It aims to help focus development on the delivery of prioritised, verifiable business value by providing a common vocabulary (also referred to as a UbiquitousLanguage) that spans the divide between Business and Technology.
It presents a framework of activity based on three core principles:
1.Business and Technology should refer to the same system in the same way - ItsAllBehaviour
2.Any system should have an identified, verifiable value to the business - WheresTheBusinessValue
3.Up-front analysis, design and planning all have a diminishing return - EnoughIsEnough
