Abstract: A method, non-transitory computer readable medium and a computerized system for adaptive regression testing. The method may include (a) generating or receiving monitoring results that are indicative of relevant data segments and relevant source code segments; (b) generating, based on the monitoring results, a first mapping that maps test cases of the multiple test cases to at least some of the relevant data segments; (c) detecting detected data changes introduced during a monitoring period that follows the execution of the regression tests; (d) selecting, based on the detected data changes and the first mapping, one or more selected test cases for evaluating an impact of the detected data changes; and (e) evaluating the impact of the detected data changes by executing the one or more selected test changes.
