ATDD e documentação de usuário como ferramentas ágeis de definição e validação de requisitos

Abstract

Agile development environments frequently use direct communication with customers in order to refine requirements. This approach works fine for software products developed for a single customer. Some problems emerge when software is part of a product, as in telecommunication devices and smartphones. The different device models can have functionalities performed by hardware or software part. Depending on the target market of these products and requiring the same tests to be performed on many devices. In this scenario with software as part of a product, it grows the need for agile requirements definition in the first product containing a functionality. The next products should have the same requirements validated. The use of Acceptance Test Driven Development (ATDD) creates an executable version of the requirements document validation and an agile definition of the tests that should be executed to validate them. This work presents the increase of understanding of requirements when we use the customer documentation in conjunction with ATDD to improve the interaction between user, customers, testers and developers.
