Software product line (SPL) testing is a challenging task, due to the huge number of variants sharing common functionalities to be taken into account for efficient testing. By adopting the concept of regression testing, incremental SPL testing strategies exploit the reuse potential of test artifacts between subsequent variants under test. In previous work, we proposed delta-oriented test case prioritization for incremental SPL integration testing, where differences between architecture test

However, the prioritization left two issues open: (1) changes to component behavior are ignored, influencing component interactions and, (2) the weighting and ordering of similar test cases result in an unintended clustering of test cases. In this paper, we extend the test case prioritization technique by (1) incorporating changes to component behavior allowing for a more fine-grained analysis and (2) defining a dissimilarity measure to avoid clustered test case orders. We prototyped our test case prioritization technique and evaluated its applicability and effectiveness by means of a case study from the automotive domain showing positive results.
