Performing functionality testing in serviceoriented architectures is not a trivial task. The difficulty is especially the large number of components that may be present in a SOA such as brokers, providers, service registries, clients, monitoring tools, data storage tools, etc. Thus, in order to facilitate the process of conducting functional testing and capacity planning in service-oriented systems,...
Accurate and rapid evaluation of web service performance is a key problem of Service-Oriented Architecture (SOA), where services are continuously being (re-)designed and released, and integrated within heterogeneous environments. Unfortunately, pre-deployment testing of services is not suitable to evaluate service performance at both design time and runtime. As a result, often process designers get...
Developers often rely on penetration testing tools to detect vulnerabilities in web services, although frequently without really knowing their effectiveness. In fact, the lack of information on the internal state of the tested services and the complexity and variability of the responses analyzed, limits the effectiveness of such technique, highlighting the importance of evaluating and improving existing...
Web services are widely known as the building blocks of typical service oriented applications. The performance of such an application system is mainly dependent on that of component web services. Thus the effective load testing of web services is of great importance to understand and improve the performance of a service oriented system. However, existing Web Service load testing tools ignore the real...
The paper focuses on developing a cloud energy-saving and data-mining information agent with Web service techniques. It could explore related technologies to establish a Web service platform, and study how to construct cloud interactive diagrams to employ Web service techniques for extensively and seamlessly integrating an energy-saving and data-mining information agent in the Internet. The preliminary...
With powerful features and cross platform character, web service has been applied in the field of information technology widely. To meet dynamic needs of enterprises, it tends to generate new web applications through service compositions. Due to flaw of designed process or incorrect input, to composite service may encounter various faults during execution. Moreover, the faults often continue to accumulate...
Service-oriented architectures and web services have been used to foster the development of loosely coupled, interoperable, and distributed applications. Mission-critical and business process systems can be implemented with them, requiring a high level of quality. Model-based testing allied with state models is a promising candidate due to its efficiency, effectiveness, and flexibility. In this paper,...
Web services are often deployed with critical software bugs that may be maliciously exploited. Developers often trust on penetration testing tools to detect those vulnerabilities but the effectiveness of such technique is limited by the lack of information on the internal state of the tested services. This paper proposes a new approach for the detection of injection vulnerabilities in web services...
This paper presents a methodology for generating a web service "stub" that simulates the behaviour of a real-world SOAP web service. The simulation is driven by a formal description of the original service's input and output parameters, messages, and ordering constraints between messages, using an extension of Linear Temporal Logic called LTL-FO+. This logic is rich enough to express complex...
Electronic collaboration over the Internet between business partners appear to be converging toward well-established types of message exchange patterns that involve both user-defined standards and infrastructure standards. At the same time, the notion of event is increasingly promoted for asynchronous communication and coordination in SOA systems. In collaboration between partners or between components...

Research efforts have been gradually invested in online automatic business system health-checking in order to improve enterprise business capability in real-time. The paper proposes a service-based framework to automatically check the health situation of business execution in online way. Based on enterprise organizational behavior analysis, paper establishes collaborative health-checking system by...
Service Oriented Architectures (SOA) have emerged as a promising solution to develop interoperable and highly dynamic applications. In the domain of SOA, Service Level Agreements (SLAs) are used to specify the stipulated terms between the service provider and the consumer. Due to the unique features of this paradigm such as SLA management, testing SOA presents new challenges to researchers because...
This paper presents a formal framework to perform passive testing of service-oriented systems. Our approach uses the historical interaction files between web services to check the absence of faults. It uses a set of properties, that we call invariants, to represent the most relevant expected behaviour of the web services under test. Intuitively, an invariant expresses the fact that each time the system...
Web Services are applied widely in the field of information technology, and performance testing for Web Services applications has become an important problem. This paper introduces the method of performance testing, and proposes a framework of agent-based performance testing on Web Services, which includes TestFlow Generator, Scenario Creator, Test Manager, Load Generation Agent and Test Analyzer...
The system utilizes the object-oriented analysis method and the broad-based B / S / D software architecture. Then researching and developing the coal mining security equipment's intelligent monitoring and management system of being based on the web-environment, the Web server software on this system using the tomcat6.0. Connecting the database by struts and ibatis dynamic web page technology and framework...
Assurance is an essential part of building any software system because it provides confidence and reduces the risks associated with system implementation. Assurance of service-oriented systems is similar to assurance of any distributed system. However, service-oriented environments have additional challenges because of their unique characteristics-reduced control, observability, visibility, and trust;...
Service monitoring is an essential part of service-oriented software systems and is required for meeting regulatory requirements, verifying compliance to service-level agreements, optimising system performance, and minimising the cost of hosting Web services. However, service monitoring comes with a cost, including a performance impact on the monitored services and systems. Therefore, it is important...
One part of trustfulness on web services application over the network is confidence of services that providers can guarantee to their customers. Therefore, after the development process, web services developers must be sure that the delivered services are qualified for availability and reliability during their execution. However, there is a critical problem when errors occur during the execution time...
Web services exposing run-time behaviour that deviates from their behavioural specifications represent a major threat to the sustainability of a service-oriented ecosystem. It is therefore critical to verify the behavioural conformance of services during run-time. This paper discusses a novel approach for run-time verification of Web services. It proposes the utilisation of Stream X-machines for constructing...
