Clustering based novel test case prioritization technique

Regression testing is an activity during the maintenance phase to validate the changes made to the software and to ensure that these changes would not affect the previously verified code or functionality. Often, regression testing is performed with limited computing resources and time budget. So in this phase, it is infeasible to run the complete test suite Thus, test-case prioritization approaches are applied to ensure the execution of test cases in some prioritized order and to achieve some specific goals like, increasing the rate of bug detection, identifying the most critical bugs as early as possible etc. In this research work, we are going to propose a new and more effective clustering based prioritization technique that uses various metrics and execution time of test cases to reorder them. The results of implementation will prove that the suggested approach is more productive than the existing coverage and clustering based prioritization techniques.
