Clustering Test Cases in Web Application Regression Testing using Self-Organizing Maps

In the software testing domain, different techniques and approaches are used to support the process of regression testing in an effective way. Test case prioritization techniques improve the performance of regression testing, and arrange test cases in order to detect the faults in a reasonable amount of time. User-session is a unique feature of web applications that is useful in the process of regression testing as they comprise precious information about the application state before and after any change that is made to the software code. The main challenge is the effectiveness of average percentage fault detection rate and time constraint in the existing techniques. Thus, in this research the priority is given to the test cases, clustered according to some criteria. Using self-organizing map for clustering helps to obtain a higher fault detection rate in a relatively small time span.
