On the Reuse of Existing Configurations for Testing Evolving Feature Models
Andrea Bombarda, Silvia Bonfanti, Angelo Gargantini · 2023
Software Product Lines (SPLs) are used for representing a variety of highly configurable systems or families of systems. They are commonly represented by feature models (FMs). Starting from FMs, configurations, used as test cases, can be generated to identify the products of interest for further activities. As the other types of software, SPLs and their FMs may evolve due to changing requirements or bug-fixing. However, no guidance is usually given on what to do with derived configurations when an FM evolves. The common approach is based on generating all configurations from scratch, which is not optimal since a greater effort is required for concretizing the new tests, and some of the old ones may be still applicable.
