Abstract. On Service-Oriented Architectures (SOAs), the mechanism for run-time discovery and selection of services may conflict with the need to make sure that business process instances satisfy their reliability requirements. In this paper we describe a certification scheme based on machine-readable reliability certificates that will enable run-time negotiation. Service reliability is afforded by means of reliability patterns. Our certificates describe the reliability mechanism implemented by a service and the reliability pattern used to implement such a mechanism. Digital signature is used to associate the reliability claim contained in each certificate with the party (service supplier or accredited third-party) taking responsibility for it.

“…The possibility of enhancing the functionality of a UDDI service broker with logic that permits to perform a testing step before registering a service has been firstly proposed in [28] and [27], and subsequently in [20]. This idea is also the basis for the framework introduced in this paper.…”

“…With reference to the information that must be provided with the WS description, the authors of [28] foresee that the WS developer provides precise test suites that can be run by the enhanced UDDI. In [20] instead the authors propose to include Graph Transformation Rules that will enable the automatic derivation of meaningful test cases that can be used to assess the behavior of the WS when running in the "real world".…”

Abstract.A Web Service (WS) is a type of component specifically conceived for distributed machine-to-machine interaction. Interoperability between WSs involves both data and messages exchanged and protocols of usage, and is pursued via the establishment of standard specifications to which service providers must conform. In previous work we have envisaged a framework for WS testing. Within this framework, this paper focuses on how the intended protocol of access for a standard service could be specified, and especially on how the conformance of a service instance to this specified protocol can then be tested. We propose to augment the WSDL description with a UML2.0 Protocol State Machine (PSM) diagram. The PSM is intended to express how, and under which conditions, the service provided by a component through its ports and interfaces can be accessed by a client. We then propose to translate the PSM to a Symbolic Transition System, to which existing formal testing theory and tools can be readily applied for conformance evaluation. A simple example illustrates the approach and highlights the peculiar challenges raised by WS conformance testing.

“…Some similar broker based architectures were presented in [12] and [13] that focus more on the QoS specification using XML schema, and dynamic QoS mapping between server and network performance. In [14], Tsai et al suggested test scripts specification techniques to perform testing with the UDDI server. The verification tests are performed in UDDI registry that does not support QoS-aware web service publication and discovery.…”
