ABSTRACT Test case prioritization techniques improve the cost-effectiveness of regression testing and provide several benefits such as earlier detection of faults and earlier feedback to testers. This paper provides an overview of existing research in the area of test case prioritization and reviews 70 journal articles and conference papers. We show the state of the research and a new classification schema for test case prioritization techniques. Existing research is discussed with respect to the test case prioritization approaches and the performance evaluation parameter criteria used in the studies.
