ANALYSIS ON TEST CASE ASSORTMENT AND PRIORITIZATION STRATEGY

ANALYSIS ON TEST CASE ASSORTMENT AND PRIORITIZATION STRATEGY Author: Mukund Keywords: Regression,Test case Selection,Test Case Prioritization, Motivation The purpose of the regression testing is to give the confidence about the product, as the existing functionality works as expected and not hampered due to the changes made to the existing software, in order to implementing the new features. It has become more complex due to the trends like component-based development as a small change in the component leads to an entire testing of the module. This phenomenon is more likely to happen in the agile development and has become more complex as for every iteration a new set of test cases will be added, and test effort increases cumulatively. Key Problem 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. 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. Methodology Address the issue, test suite optimization has been classified into three categories test case reduction, selection and prioritization literature review is done for the same, a prototype model to be designed to analyze the regression analysis mentioned in literature. Predictions and Results Regression testing is very expensive, and many techniques have been proposed for reducing the cost of regression testing. Conclusion Research in the areas of test case selection and prioritization with explanation of each technique.
