Utilization of Dependence and Weight to Improve Fault Localization Method of Regression Test Cases
Hui Zhang · International Journal of Software Engineering and Knowledge Engineering · 2017
Among the fault localization methods of the coverage-based regression test cases, the ranking of suspiciousness degree is seriously impacted due to the existence of similar test cases, the existence of isolated treatment of each program entity and the coincidental correctness test cases as well as the poor quality of regression test cases, which reduces the efficiency of fault localization. This paper proposes a method that combines the control dependence and data dependence, test cases covering table and test result with vector angular cosine weight to solve the aforesaid problems. Experimental results show that the efficiency of the proposed fault localization of regression test cases is better than that of Tarantula, Jaccard, Ochiai, PPDG and CP methods.
