“…Tsai et al [9] believe that all Web services parties (including service providers, service brokers, and service requestors) must collaborate to perform Web services testing [9,10]. The essential technique of their collaborative group testing approach is to construct trustworthy service brokers and utilize distributed agents to rank and vote for appropriate services based upon service histories.…”

The Web services technology has received significant momentum in recent years, because it allows people to easily utilize and integrate existing software applications to rapidly create new business services. However, how to ensure the trustworthiness of a Web services-oriented system remains a big challenge. One critical issue is how to test a Web service in an effective and efficient manner. In this paper, we report our design and development of a novel mobile agent-based method oriented to Web services testing. We seamlessly integrate an existing testing tool (HP LoadRunner) with a mobile agent technology (IBM Aglet) to build a practical environment for testing Web services. We also report an automatic test case generation algorithm, which analyzes published Web service interfaces and creates boundary value-based, fault injection-equipped test cases.

“…Bai et al also proposed a contract‐based collaborative testing approach that extends the enhanced UDDI proposal of Tsai et al Bai et al proposed a decentralized collaborative validation and verification (DCV&V) framework with contracts. The proposed framework consists of distributed test brokers that handle a specific part of the testing process.…”

SUMMARYService‐oriented architecture (SOA) is gaining momentum as an emerging distributed system architecture for business‐to‐business collaborations. This momentum can be observed in both industry and academic research. SOA presents new challenges and opportunities for testing and verification, leading to an upsurge in research. This paper surveys the previous work undertaken on testing and verification of service‐centric systems, which in total are 177 papers, showing the strengths and weaknesses of current strategies and testing tools and identifying issues for future work.

“…Apart from interface-based Web service testing, different methods have been proposed for, e.g., group testing [17], collaborative contract-based testing [2], and testing of data-centric service compositions [14,11]. Further coverage criteria have been defined for operation/message combinations [5], and execution paths in processes defined with the Web Services Business Process Execution Language (WS-BPEL) [10,13].…”

We address the problem of interface-based test coverage for Web services.We suggest an approach to analyze the Application Programming Interface (API) of Web services, calculate the number of possible input combinations and compare it to the number of actual historical invocations. Such API coverage metrics are an indicator to which extent the service has been used. Measuring API coverage is a key concern for assessing the significance of Verification and Validation (V&V) techniques; on the other hand, API coverage metrics can also yield interesting usage reports for a service-based system in production use. The coverage metrics rely on the exact specification of service interfaces, and we provide a mechanism to specify restrictions for data types in the Java Web services framework (JAX-WS). As full enumeration of all possible inputs is often infeasible, we allow the definition of custom coverage metrics by means of domain partitioning: the user divides domain ranges into subsets, and a coverage of 100% means that the logged invocations contain at least one sample for each subset. Based on a prototype implementation, we evaluate different aspects of our approach.
