Abstract:

This talk proposes a service oriented architecture for collaborative testing
of Web Services (WS) using Semantic Web Services. In this architecture, test
tasks are completed through the collaboration of various WS that provide and
request test services and related information. Such test services are
registered, discovered and invoked at runtime using the ontology of software
testing STOWS (Software Testing Ontology for WS). The composition of test
services can, for example, be realized by using test brokers, which are also
test services but specialized in the composition and coordination of test
services. The ontology can be extended and updated through an ontology
management service so that it can be populated for supporting a wide and
open range of test activities, methods, techniques as well as for dealing
with various types of software artifacts in different formats. The talk also
presents a prototype implementation of the architecture in the framework of
Semantic WS using OWL-S to represent the ontology STOWS and use Matchmaker
to search for test services based on semantic information. A prototype test
broker has also been developed to support the composition of test services.
Three case studies are reported to demonstrate the feasibility of the
architecture. They illustrate how to wrap a general purpose software testing
tool into a test service, how to develop a specific test service for
performing test executions of a WS, and how to collaborate test services to
conduct more complicate testing tasks.
