Editing Web service (section)

===Regression testing of Web services===
Functional and non-functional testing of Web services is done with the help of WSDL parsing. [[Regression testing]] is performed by identifying the changes made to upgrade software. Web service regression testing needs can be categorized in three different ways, namely, changes in WSDL, changes in the code, and selective re-testing of operations. We can capture the above three needs in three intermediate forms of Subset WSDL,<ref name=SWSDL /> namely, Difference WSDL (DWSDL), Unit WSDL (UWSDL), and Reduced WSDL (RWSDL), respectively. These three Subset WSDLs are then combined to form Combined WSDL (CWSDL) that is further used for regression testing of the Web service. This will help in Automated Web Service Change Management (AWSCM),<ref name=AWSCM /> by performing the selection of the relevant test cases to construct a reduced test suite from the old test suite.

Web services testing can also be automated using several test automation tools like [[SoapUI]], [[Oracle Application Testing Suite]] (OATS),<ref>[http://www.oracle.com/technetwork/oem/app-test/etest-101273.html Oracle Application Testing Suite]</ref><ref>[http://www.testingtools.co/automation/web-services-testing-using-oracle-application-testing-suite-oats Web Services Testing using Oracle Application Testing Suite]</ref> Unified Functional Testing, Selenium, etc.
