Adaptação do produto backlog para geração de scenarios utilizando desenvolvimento dirigido a comportamento

Abstract

Scrum is an agile method used to coordinate projects and it is used in software development. Although it is considered a methodology, Scrum is a framework that assist in software process coordination, defining phases that determine which tasks must be finished until a certain portion of the project is complete. On the first steps of Scrum, a list is created with the system’s functionalities and descriptions. This list is called Product Backlog an it’s items follow the User Story format, which are scenarios that contain simple descriptions, written in the natural language and explain how the functionalities must be executed. The concept of Scenarios are used in the Behavior Driven Development (BDD) and allow the smaller scopes to be defined so that they can be tested, assuring the quality of the system. A similar concept to Scenarios are User Stories inserted as items of the Product Backlog, which are in turn defined by the functionalities described by the Product Owner. User Story validation is not an automated process, therefore the use of BDD Scenarios can solve this issue. This paper created a conversion formalism between the Product Backlog and Scenarios, automating not only further tests, but the initial requirement analysis as well. This paper also proposes a modified format of the Product Backlog in which new information can serve as input for the Scenarios of BDD tools. By means of the proposed formalism, using Backus-Naur-Form (BNF), it accomplishes the integration between a software development process (Scrum - Product Backlog) and a behavior driven development (BDD) for the automated generation of tested using as a base scenarios created during the requirement analysis.
