    A Case Study Using Testing Technique for Software as a Service (SaaS)
    th International Conference on Information Technology New Generations ITNG IEEE
    Mar 2015
    In the second semester of 2013, during the development of the Customer Relationship Management (CRM) System at Brazilian global company, there was the necessity to execute software testing. However, it was done using techniques, such as Script-based Testing, Integration Testing and User Acceptance Testing. These techniques were inadequate to the cloud environment. Thus, the pairwise technique was chosen for the software cloud testing. Comparing the results from the traditional techniques to the pairwise testing it was noticed that the number of test cases was reduced and testing time was cut by one-sixth. So, it was concluded that pairwise testing is effective as an initial testing technique in the cloud, in conditions in which it is applic

    Um Estudo Conceitual sobre Certificação de Software Embarcado Aeronáutico
    Congresso Nacional de Iniciação Científica
    Nov 2014
    Ao longo de todo o processo de desenvolvimento e certificação de software embarcados, diversos procedimentos devem ser executados. Para isso o desenvolvimento passa por uma rigorosa fiscalização dos órgãos de regulamentação civil. DO-178C (Software Considerations in Airborne Systems and Equipment Certification) e suplementares, todas normas criadas pela RTCA, foram criadas para servir de base na execução de todos esses processos. O estudo visa apresentar um overview sobre o processo de desenvolvimento e certificação de sistemas embarcados aeronáuticos. DO-178C descreve todo o processo de desenvolvimento de um software embarcado, proporcionando um completo suporte a essa atividade. Todas essas etapas desde a coleta de requisitos do sistema,
