Modular based multiple test case prioritization

Cost and time effective reliable test case prioritization technique is the need for present software industries. The test case prioritization for the entire program consumes more time and the selection of test case for entire software is also affecting the test performance. In order to alleviate the above problem a new methodology using modular based test case prioritization is proposed for regression testing. In this method the program is divided into multiple modules. The test cases corresponding to each module is prioritized first. In the second stage, the individual modular based prioritized test suites are combined together and further prioritized for the whole program. This method is verified for fault coverage and compared with overall program test case prioritization method. The proposed method is assessed using three standard applications namely University Students Monitoring System, Hospital Management System, and Industrial Process Operation System. The empirical studies show that the proposed algorithm is significantly performed well. The superiority of the proposed method is also highlighted.
