An Approach to IMPROVING THE PRICE EFFECTIVE TESTING METHOD FOR REGRESSION TESTING EXPLOITATION METAHEURISTIC TECHNIQUE

Abstract

Regression testing is a very expensive and time constrained process as there may be insufficient resources to reexecute all the test cases in resource and time constrained environment. It acquires a lot of human effort, if done manually. Lot of techniques have been reported on how to select regression tests so that the number of test cases do not boast up too high as the software evolves. Thetechniques include regression test selection, test minimization and test prioritization. In this paper various met heuristic approaches have been studied to examine their potential benefits to regression testing. The paper also addresses the problem of choice of fitness metric and determination of the most suitable search technique to apply. Genetic algorithm performs well, although Greedy approaches are surprisingly effective, given the multimodal nature of the landscape. It may be accomplished that Cucuta ordering which is inspired by intelligent behavior of plants gives same results as given by the optimal and ACO ordering but better than ordered, random and reverse order. The study also reveals that ABC outperforms the other approaches i.e. GA, ACO, BCO and PSO in test suite optimization process as parallel behavior of the bees is used to reach the solution generation faster.
