Fault localization is an important step in software debugging that aims to isolate and localize the bugs (errors) to a small part of the program. This becomes more challenging in Software Product Lines (SPLs) due to the variable nature of bugs (so-called variability bugs). This paper introduces a novel variability fault localization algorithm for SPLs. Moreover, we present its practical application for automatic repair of variability bugs in SPLs.
