A Survey on Test Case Selection and Prioritization Techniques

One of the expectations from Agile software development is to reduce the cost of the project as the Agile development methodology focuses on delivering the right product and eliminating the waste.However, with shorter project cycles, smaller and agile teams the cost is not going down [3].This emphasis the focus to re look at the phases in the software product development and one such area is regression testing.Regression testing is one of the most expensive yet important phase in software development, hence cannot be completely ignored, however can be reduced or minimized without compromising on the quality of the product.Researchers used several techniques to reduce and prioritize the test cases.In this paper we have presented various techniques presented to test case selection and prioritization.
