ABSTRACT
We are developing a language, Web Service Offerings Language
(WSOL), for the formal specification of various constraints, management statements, and classes of service for Web Services.
WSOL is an XML (Extensible Markup Language) notation compatible with WSDL (Web Services Description Language).
A service offering in WSOL is a formal description of one class of service of a Web Service. It contains formal representation of various constraints: functional (pre-, post-, and futureconditions), Quality of Service (QoS, a.k.a. non-functional, extrafunctional), and access rights. It also contains management statements, such as statements about prices, monetary penalties, and management responsibilities. One Web Service can be associated with multiple service offerings. For easier specification of similar service offerings, WSOL enables specification of constraint groups (CGs) and constraint group templates (CGTs). We have also developed a format for representation of dynamic relationships between service offerings. WSOL service offerings are simple contracts and SLAs (Service
Level Agreements) between Web Services. Describing a Web
Service in WSOL, in addition to WSDL, enables monitoring, metering, and management of Web Services. The Web Service, its consumer, or one or more designated third parties (usually
SOAP message intermediaries) can meter QoS metrics and evaluate constraints in WSOL

    The constraints which ultimately compromise the project’s performance are the quality the driver constraints. These are constraints that do not fail without dragging the project down to failure along with it. This is also the least flexible of all the constraints. The other constraint is the middle constraint which are constraints that are not as rigid as the driver constraints neither they are very flexible. The last one is the weak constraint which is the most flexible constraints. These constraints are very important but still possess the greatest flexibility.…

    Collaborative Testing of Web Services

    Abstract—Software testers are confronted with great challenges in testing Web Services (WS) especially when integrating to services owned by other vendors. They must deal with the diversity of implementation techniques used by the other services and to meet a wide range of test requirements. However, they are in lack of software artifacts, the means of control over test executions and observation on the internal behavior of the other services. An automated testing technique must be developed to be capable of testing on-the-fly nonintrusively and nondisruptively. Addressing these problems, this paper proposes a framework of collaborative testing in which test tasks are completed through the collaboration of various test services that are registered, discovered, and invoked at runtime using the ontology of software testing STOWS. The composition of test services is realized by using test brokers, which are also test services but specialized in the coordination of other test services. The ontology can be extended and updated through an ontology management service so that it can support a wide open range of test activities, methods, techniques, and types of software artifacts. The paper presents a prototype implementation of the framework in semantic WS and demonstrates the feasibility of the framework by running examples of building a testing tool as a test service, developing a service for test executions of a WS, and composing existing test services for more complicated testing tasks. Experimental evaluation of the framework has also demonstrated its scalability. Index Terms—Software engineering, software testing, distributed/internet based software engineering tools and techniques, testing tools, ontology, web services, semantic web services, service composition.…
