Evolução da ferramenta web guitar para geração automática de casos de teste de interface para aplicações web

Abstract

Web applications are in our daily routine and are fundamental in several areas, such as education, health, and entertainment. A failure in these applications can cause financial loss, so it is essential to ensure their quality. One way to achieve this goal is through software testing. Although the testing activities bring many benefits, they add cost to a software development project, which should be reduced. A strategy used for this is testing automation. Repetitive and error prone activities are strong candidates to be automated, among them we can mention the test cases generation. The Web Guitar tool enables the generation and execution of test cases from the structural model of Web application under test. This model presents problems related to its accuracy. Thus, this work proposes its evolution aiming to increase the number of generated test cases and improve their quality. As contribution, a new version of Web Guitar tool was implemented to sweep a web application identifying new GUI elements and visiting different instances of a same page in order to provide a more complete model. The results obtained in a case study performed with two Web applications, System to Support PPGI/UFAM and DiskTransito, provided evidence of the feasibility of this work, since the proposed tool (WG-Modified) contributed to the generation of a greater number of test cases for System to Support PPGI/UFAM, despite its execution time exceed the time calculated for the original tool. When analyzing the time required to generate each test case, WG-Modified was more efficient than its original version. However, the results of this study for the second application (DiskTransito) showed some problems and limitations that will be addressed in future works.
