Fault-Based Regression Test Case Prioritization

Abstract

We propose a set of four novel fault-based regression test case prioritization (TCP) techniques for object-oriented programs. We seed bugs into a program to create large number of mutants. We execute each mutant with the originally designed test suite. From this, we record the number of mutants for which a test case fails. Based on this, we prioritize the test cases using four base fault-based prioritization techniques that we have proposed. Finally, we combine the results of our four base prioritizers using three ensemble methods. We have conducted experimental studies to determine the effectiveness of our proposed approaches. Our experimental results show that our proposed TCP techniques exhibit superior performance over related techniques.
