Abstract: We present a new root cause analysis algorithm for discovering the most likely causes of differences found in testing results of two versions of the same software. Problematic points in test and environment attribute hierarchies are presented to a user in a compact way which in turn allows saving time on test result processing. We have proven that for clearly separated problem causes our algorithm gives an exact solution. Practical application of described method is discussed.

Keywords: root cause analysis, software regression testing, hierarchy graphs
