Prioritization of Test Cases using Branch Coverage with Multiple criteria for Regression Testing

Abstract — Prioritization of test cases is generally done to reduce the cost of regression testing. We prioritize our test cases so that those which are more important, by some measure, are made to run earlier in the testing phase. There exists a large variety of prioritization techniques in the literature, we have basically used coverage-based prioritization techniques (i.e., prioritization in terms of the number of statements, path coverage, branch coverage and fault coverage) controlling the field. A prioritized test suite which covers more than one coverage criteria is considered to be a stronger than those which cover only single coverage. The proposed method was empirically studied for bank application and the results show that the proposed work is more effective than the existing method
