Optimization of Test Cases in Regression Testing with Different Techniques

The relevance of Software Testing (ST) in the Software Development Life Cycle (SDLC) should never be underestimated. Smarter ST can provide us with more reliable and defect-free goods that meet our stakeholder demands. That is why it requires more time and resources. Unfortunately, the product has reached the testing stage, particularly in Regression Testing (RT), with just a short time remaining. Regression testing is one of the testing approaches used to ensure that changes made in repairs or other improvements do not impair the software’s previously produced functionality. As a result, regression testing plays an important role in software testing. A generic software may change as a result of bug fixes, adaption to new environments, upgrading or updating functionality to increase performance, or as requested by a client. After the programme has been provided to the customer, the generic software must be regressed to ensure that there are no flaws. Test case prioritisation aims to order test cases so that early issue identification is maximised. This paper examines each type of minimization, selection, and prioritisation strategy for future research.
