Criação de um processo de refatoração de software para site web: um estudo de caso nas páginas do LESIC

Abstract

Refactoring is an essential technique to maintain control and code quality in web, desktop, or mobile software development projects. This technique involves improving the code structure without altering its external behavior, aiming to enhance the software design throughout its development. This prevents the loss of structure caused by unplanned cumulative changes. This work has created a refactoring process for web projects, consisting of four stages: Planning, Analysis, Implementation, and Evaluation. The design of this process was conceived due to the absence of an approach in the literature that includes website refactoring. The process was applied to the Laboratory of Software Engineering and Computational Intelligence (LESIC) website project, focusing on the back-end of the administrative area. Planning involved understanding functionalities, creating scenarios, and identifying inputs and outputs. Analysis was conducted manually and automated using the SonarQube refactoring tool, detecting issues in the source code that were refactored using refactoring techniques or design patterns. In the Implementation stage, ninety-three-unit tests were developed using the PHPUnit library since the LESIC website did not have them. In the evaluation stage, the application of refactoring increased the security, maintenance, and reliability of the project. Regarding the process, it can be reused by other developers wishing to refactor a web project.
