Many composite workflow services utilize non-imperative XML technologies such as WSDL, XPath, XML schema, and XML messages. Regression testing should assure the services against regression faults that appear in both the workflows and these artifacts. In this paper, we propose a refinement-oriented level-exploration strategy and a multilevel coverage model that captures progressively the coverage of...
In real life, a tester can only afford to apply one test case prioritization technique to one test suite against a service-oriented workflow application once in the regression testing of the application, even if it results in an adverse scenario such that the actual performance in the test session is far below the average. It is unclear whether the factors of test case prioritization techniques known...
Many web services represent their artifacts in the semi-structural format. Such artifacts may or may not be structurally complex. Many existing test case prioritization techniques however treat test cases of different complexity generically. In this paper, we exploit the insights on the structural similarity of XML-based artifacts between test cases, and propose a family of test case prioritization...
A web service may evolve autonomously, making peer web services in the same service composition uncertain as to whether the evolved behaviors may still be compatible to its originally collaborative agreement. Although peer services may wish to conduct regression testing to verify the original collaboration, the source code of the former service can be inaccessible to them. Traditional code-based regression...
Programs using service-oriented architecture (SOA) often feature ultra-late binding among components. These components have well-defined interfaces and are known as Web services. Messages between every pair of Web services dually conform to the output interface of a sender and the input interface of a receiver. Unit testing of Web services should not only test the logic of Web services, but also assure...
WS-BPEL applications are a kind of service-oriented application. They use XPath extensively to integrate loosely-coupled workflow steps. However, XPath may extract wrong data from the XML messages received, resulting in erroneous results in the integrated process. Surprisingly, although XPath plays a key role in workflow integration, inadequate researches have been conducted to address the important...
