The development of a city gradually forms different functional regions, such as residential districts and shopping areas. Discovering these functional regions in cities can enable new types of valuable applications that can benefit different end users: Urban planners can better identify the proximity of existing functional regions and hence, can contribute a better future planning for the cities....
Web services are widely used nowadays for their interoperability and reusability. Since Web services only provide interface information for users and source codes are encapsulated, generating test cases for Web services in the view of users has more challenges than traditional software. We develop a constraint-solver based method to generate test cases for composite Web services. The technique first...
A typical business model in cloud environments for service providers is the provision of composite services built from resources and services offered by other providers. Customers of these composite services can make an advance payment before consumption. In this scenario, accounting systems will supervise each service comprising given composite services individually. As the number of constituent...
Regression testing is necessary to assure the quality of service-oriented business applications in their evolutions. However, because of the constraint of testing resource, entire test suite may not run as a result. Therefore, test case prioritization technique is required to increase the efficiency of Web service application regression testing. In this paper, we propose a dependence analysis based...
If environments offering facilities for service composition are to be commercially successful then it will be important that service providers can avail of efficient, automated processes by which composed services can be metered, charged and billed for. In many industries, for example telecommunications, sophisticated systems are employed to provide usage and content based charging for services. In...
For large and complex composite Web services which are composed by BPEL and a set of WSDL and XSD documents, we urgently need the aid of the tools in designing and selecting test cases. However, most of mature testing tools which generate test data with the information of WSDL are used for single service while the research for composition remains in the realm of theory. So we apply the theory of data-flow...
Quality function deployment (QFD) is a customer-oriented structural development approach in manufacturing whereas the Gap model told us the truth of service psychological process. Along the gaps in the circle of service satisfaction, a new model of service quality function deployment (SQFD) has been established to develop new service. A Chinese mobile telecom case study (hall service) has been employed...
At present, most of Web applications have multi-tier architectures. The Web application contains many components, which makes it become component-based Web application. This paper focuses on this kind of Web applications and constructs three dependency graphs based on structure relations and message call relations. Then we improve the path-based integration testing method, propose an extended MM-path...
