Analisando o impacto de inter-smell na manutenibilidade de linhas de produto de software : um estudo de caso

Abstract

A Software Product Line (SPL) consists of a systematic reuse strategy to construct systems with less effort as long as they belong to the same family that share the same components and belong to the same domain of Marketplace. Software reuse is considered one of the most powerful ways to address the challenges in developing software systems for benefits such as software quality, shorter lead times and lower costs. In this context, to support large-scale reuse, components of a Software Product Line (SPL) should be easy to maintain. Thus, developers should be more concerned with anomalies known as code smells and more than that, co-occurrences known as Inter-smell deserve to be further studied to verify their real impact on maintainability in SPL. Thus, this paper conducts a case study to investigate the impact of Inter-smell occurrences on maintainability in MobileMedia and HealthWatcher SPL. First the detection of code smells, God Class, Duplicated Code, Long Method, Feature Envy, and Type Cheking were detected. After this step, the identification of the Inter-smell relationships was measured, the quality of each release was checked against the presence of these anomalies and the removal of these relationships to compare releases with and without occurrences of Inter-smell. The results show that the presence of co-occurrences of Inter-smell did not negatively impact the maintenance of MobileMedia and Health Watcher SPL, unlike results found in other studies in the literature, and even more, our results indicate that the metric LOCK of Cohesion of Methods LCOM is one of the most important for the maintainability of object-oriented SPL.
