SPLIT: um conjunto de técnicas de inspeção em modelos de linha de produto de software

Abstract

Software Product Lines enable organizations to develop a number of similar products in the same application domain, which reduces development time and maintenance cost, and increases productivity. Software product line specifications need to be evaluated for improving software. In this context, software inspections aims do guarantee complete, consistent and correct artifacts finding defects in early stages in software lifecycle. In this work, we propose SPLIT (Software Product Line Inspection Technique), which is a set of modelbased inspection techniques for evaluating software product line specifications. A feasibility study was conducted for comparing SPLIT against a defect type-based inspection approach. The object of the feasibility study was a Twitter client software product line specification created for the experiment. The results indicated that the set of techniques found a greater number of defects than a defect type-based inspection approach. A second empirical study was conducted for comparing SPLIT against a defect type-based inspection approach using a real software product line for mobile robot vehicles. This study aimed to verify whether the set of techniques fits real world life-cycle development. The second empirical results supported the feasibility study in which SPLIT found a greater number of defects than a defect type-based inspection approach. Thus, software product line quality assurance can be improved using SPLIT for detecting defects in early stage of development.
