As a principle of project delivery Agile has always been about achieving better outcomes faster through the use of a dynamic collaborative framework than traditional methodologies. Behaviour Driven development BDD offers a modern agile software development approach which is seen as an evolution of Test Driven Development TDD and Acceptance Test Driven Development ATDD . It introduces new methods and strategies that describes user behaviours by using an ubiquitous language Gherkin which are shared understanding of requirements between everyone involved in the software projects. This helps to improve communication and collaboration in the team lead to deliver higher quality software. However it is unclear to why BDD enforces better quality software than TDD and ATDD to achieve the business goals and how to automatic step definitions from the features in Gherkin. In this paper it is examined the use of BDD in Agile Testing and compared with TDD and ATDD. I also conduct an example experiment to describe a domain-specific language and make acceptance test cases can be executable using Behave framework. Keywords BDD TDD ATDD Behave Gherkin Agile Testing. 1 Introduction In recent years many companies have adopted Agile methodologies for their software development activity. The Agile concept which is defined in the Agile Manifesto and Twelve principles of Agile Software 7 . Many software companies use these principles to deliver value and quality projects to customers. In fact VersionOne the 14 annual State of Agile survey a look into the global state of enterprise Agile in 2020 27 reported that 95 of organizations practice Agile development. The top benefits realized by companies are reported such as ability .
