A SURVEY ON SOFTWARE PRODUCT-LINE TESTING

SPL (Software Product Line) is known as a set of software systems that share a mutual set of features. It is a powerful concept to achieve more efficient software system development. One of the necessary steps in software development processes is Testing. It consumes typically more than 50% of the whole development costs. Testing SPLs is challenging due to the exponential number of products in the number of features. Several approaches have been proposed to reduce the number of products to be tested. However, the testing aspect of SPL is still underdeveloped. This study aims at surveying the latest research on SPL testing to identify useful approaches and needs for future research. seven papers are classified concerning the following: the used Approach, the algorithms, and the type of testing that the research focuses on. The survey found that more validation and evaluation research is required to produce a more robust foundation for SPL testing. Finally, directions for future software product line testing recommendations.
