Critical Analysis of Issues in Audit Testing of Web Services

Web applications and their underlying parts are growing rapidly to offer services over the internet around the world. Web applications are composed of heterogeneous self-contained web services. Service requires changes due to changes in the customer requirements, to fix errors or to enhance their functionality. Regression testing is helpful in verifying that functioning of web services has not regressed after modifications or maintenance. Test suites tend to grow in size making it too costly to execute entire test suites. Audit testing of Web services is a form of regression testing with limitation on cost and time. The main challenges behind audit testing of web services descend from traditional regression testing problems, such as test case selection and prioritization for which existing solutions are nonetheless inadequate. In this paper critical analysis has been done for audit testing method. Overview of the testing and audit testing techniques presented by researchers is evaluated, various test case prioritization techniques have been discussed for the generation of minimized test suites for the test selection.
