Acquiring Testable NFRs Utilizing Goal Models Enhancing Application Requirements Analysis in Goal-Driven Software Product Lines

Software product line engineering involves reusing development assets to create a family of software systems with common features and few specific differences. Testing is crucial for evaluating software quality, encompassing both functional and non-functional requirements. However, non-functional requirements (NFRs) are often neglected in software product lines, with a primary focus on functional requirements during system configuration. This paper addresses the significance of early testing and the challenges of testing non-functional properties in software product lines. To ensure effective testing of non-functional aspects, clear and testable specifications for non-functional requirements are essential. Current practices often leave non-functional requirements unaddressed until system testing, lacking proper traceability and management. Additionally, systematic approaches are lacking to support non-functional requirements from the early stages of development, hindering their integration into product line development. In this research, we propose an approach that utilizes goal models to enhance application requirements analysis in goal-driven software product lines. By incorporating goal models, our approach enables the acquisition of testable non-functional requirements during the early stages of development. Our approach aims to improve the effectiveness and efficiency of testing non-functional properties and align them with the specified goals.
