Approaches Used for Prioritization of Test Suites

Regression testing certifies that alteration or augmentation performed is not going to impact the original functionality. To make this sure test case must rerun from the present set of test suites, although it is not possible to conclude that how much retesting is required. Various regression test selection techniques have been developed for making regression testing more effective and efficient. As test suites becomes large in size when the software progresses also tend to increase the cost and effort of re-executing the entire test suite randomly. Test Suite Prioritization approach has been studied to exploit the test suites that have been built. According to it, test suites are run in a particular order to maximise the fault detection.
