Nature Inspired Approaches for Test Case Selection in Regression Testing: A Review

To ensure that the software satisfies all necessary criteria, software testing is done. Regression Testing is an important part of software testing as it plays a crucial role in software testing procedure. It's done to make sure that everything works as it should, such that test cases with greater potential to discover faults are given higher priority. Test case selection is introduced to choose the most effective subset of test cases from a test suite, test case selection reduces the total cost, time, and effort necessary in the process of software testing. It works by removing the obsolete and redundant test cases. Within all the computational intelligence algorithms the nature inspired algorithms are highly demanded due to their increased efficiency in solving complex problems. Nature Inspired Approaches refers to the approaches derived directly from the nature. Nature acts as the main branch of knowledge that provides various solution for the complex problems. Incorporation of Nature Inspired Approaches in test case selection problem generates a subset of test cases from the test suite resulting in time, cost and effort reduction. With the use of research questions, this paper offers a thorough review of Test Case Selection methods utilizing Nature Inspired Approaches.
