Estimativa de teste de software com o processo qEstimation: um estudo de caso no desenvolvimento da ferramenta USINN Modeler

Abstract

The application of methods to stimulate software quality is critical during the software life cycle because it is a set of attributes that should satisfy the user's needs. To run a program using some particular inputs and verify that its behavior is as expected, software testing techniques are used, which apply to a software project: study, modeling, proper documentation, and a significant amount of time for the development team, which most of the time has limited time. Thus, estimating the effort of these activities becomes crucial for effective project management. Although much research has been done on software testing metrics, most proposals do not present effort estimates for testing. This paper presents the use of an existing test effort estimation approach: qEstimation, which was adopted in the development of a modeling tool, USINN Modeler. A case study was conducted to explore test effort estimation. The estimate generated exceeded the actual effort expended, so in an attempt to bring this estimate closer to the actual effort, it is necessary to reapply the approach, improving the parameters used from previous test cycles. The planning process proposed by the approach allowed the project Usinn a team of qualified testers, test case design, data estimate generation, and the first cycle of regression testing performed.
