A Survey on Software Product Line Testing

Abstract

Software product line (SPL) testing consists of two separate but closely related test engineering activities: domain testing and application testing. Various software product line testing approaches have been developed over the last decade, and surveys have been conducted on them. However, thus far none of them deeply addressed the questions of what researches have been conducted in order to overcome the challenges posed by the two separate testing activities and their relationships. Thus, this paper surveys the current software product line testing approaches by defining a reference SPL testing processes and identifying, based on them, key research perspectives that are important in SPL testing. Through this survey, we identify the researches that addressed the challenges and also derive open research opportunities from each perspective.
