Applying Acceptance Test Driven Development to a Problem Based Learning Academic Real-Time System

This paper focuses on the importance of test driven development, in an interdisciplinary academic case study, involving unauthorized access and fraud. In it, Problem Based Learning (PBL) enabled the organization of an environment for diverse knowledge and skills, favorable to experimentation and prototyping of new models, methods, techniques, and tools. The application of the principles of agile methods aimed at overcoming difficulties related to the computer systems development, such as requirement changes, uncertainties, and risks, in order to improve quality. Unlike traditional methodologies, tests were used since the beginning of the development lifecycle with Acceptance Test Driven Development (ATDD). The agile testing quadrants guided the categorized elaboration of tests during unit testing, integration testing, system testing, and acceptance testing phases. The main contribution of this article was the integrated application of PBL, ATDD, and agile development in the case study of a Real-Time Embedded System for Unauthorized Access Control and Fraud Detection (Sistema Embarcado de Tempo Real para Controle de Acessos Indevidos e Deteccao de Fraudes - SETRAIF).
