基于BPEL的Web Service组合的数据流分析测试方法

随着Web Service组合变得越来越复杂,通过测试来保证服务质量和可靠性也变得越来越重要.将传统数据流分析方法扩展用于Web Service组合测试,提出了一种基于BPEL的Web Service组合的数据流分析测试方法.该方法基于一个测试模型:Web Service组合测试模型WSCTM,该测试模型可以捕获Web Service组合的数据流接口.采用基于服务的模型WSCTM,数据流可以从3个视点来分析:服务间、服务内和服务实现构件间.从而,Web Service组合的数据流测试可以在三层上得到实现.基于以上方法,可得到Web Service组合的定义-使用链,最终可产生满足既定测试标准以获得需求Web服务组合质量要求的测试路径.

Delegation, Arbitration and High-Level Service Discovery as Key Elements of a Software Infrastructure for Pervasive Computing

The dream of pervasive computing is slowly becoming a reality. A number of projects around the world are constantly contributing ideas and solutions that are bound to change the way we interact with our environments and with one another. An essential component of the future is a software infrastructure that is capable of supporting interactions on scales ranging from a single physical space to intercontinental collaborations. Such infrastructure must help applications adapt to very diverse environments and must protect people's privacy and respect their personal preferences. In this paper we indicate a number of limitations present in the software infrastructures proposed so far (including our previous work). We then describe the framework for building an infrastructure that satisfies the abovementioned criteria. This framework hinges on the concepts of delegation, arbitration and high-level service discovery. Components of our own implementation of such an infrastructure are presented.

Evolution feature oriented model driven product line engineering approach for synergistic and dynamic service evolution in Clouds: four kinds of schema.

The proposed research will focus on developing a novel approach to solve Software Service Evolution problems in Computing Clouds. The approach will support dynamic evolution of the software service in clouds via a set of discovered evolution patterns. An initial survey informed us that such an approach does not exist yet and is in urgent need. Evolution Requirement can be classified into evolution features; researchers can describe the whole requirement by using evolution feature typology, the typology will define the relation and dependency between each features. After the evolution feature typology has been constructed, evolution model will be created to make the evolution more specific. Aspect oriented approach can be used for enhance evolution feature-model modularity. Aspect template code generation technique will be used for model transformation in the end. Product Line Engineering contains all the essential components for driving the whole evolution process.
