Abstract

Verifying Web Services (WS) in a dynamic Service Oriented Architecture (SOA) is challenging because new services can be composed at runtime using existing WS. Furthermore, in a composite service, any component can be dynamically replaced during execution if the component fails. Another challenge is that the testing is time critical because verification must be conducted at runtime and in real time. This paper compares and contrasts traditional software testing and WS testing techniques and proposes WS group testing technique鹿 to test composite services. The group testing technique also has the ability to evaluate the test scripts, automatically establish the oracle of the each test script, and identify faulty WS in a failed composite WS.
