An automated approach to regression testing of web services based on WSDL operation changes

Abstract

As web services are dynamic in natures, the process of maintenance and evolution is rapid for web services. In order to verify the impact of changes, retesting of web services is required. Testing of web services is difficult because only web service provider has the source code and both web service user and broker have WSDL specification of the service. In this paper we have extended an existing specification based regression testing of web services approach. Both original and modified WSDL specifications are compared for identification of operation level changes. Our regression test selection approach is safe as all the relevant test cases are selected as reusable. © 2013 IEEE.
