Regression testing is an important but expensive stage of software maintenance. Regression test selection addresses the problem of reducing testing cost through selecting a subset of the existing test cases or rerun.

Different change types often have different impact mechanisms, even some changes do not impact other entities in programs in spite of some dependences existed between these entities and the modified entity. In this paper, we propose a static CIA technique,...
