Change impact analysis is performed to identify the affected definition-use pairs by comparing and analyzing two-level models of the baseline and evolved versions.
BPEL composite service is modeled with a two-level model in which XCFG (eXtended Control Flow Graph) describes the behavior of BPEL process in the first level and WSDM (Web Service Description Model) depicts the interface information of composite service and partner services in the second level. To address these issues, a test case selection approach is proposed for regression testing of BPEL (Business Process Execution Language) composite service where all-uses criterion is satisfied and all the three change types are involved. In addition, there are three observable kinds of changes during the evolution, including Process change, Binding change and Interface change, which all bring impact to the data flow. However, few work has studied the test case selection problem based on the data flow testing criteria. Test case selection in the regression testing is an effective technique to ensure the correctness of modified versions meanwhile to reduce the cost of testing. Ĭomposite services evolve for various reasons.

Second, we proposed four Service Evolution Metrics that capture the evolution of a system's Version Series VS = binding, port, and service in WSDL documents of both composite service and partner services, T u, M u, O u, P T u, B u, P u, and S u respectively denote the number of covered changes of each element, then we have. These labels are then used to identify subsets of the operations in our newly proposed Interface (WSDL) Slicing algorithm. To compare old and new versions, the following change classification labels are used: inserted, deleted, and modified. First, we propose a Service Change Classifier based Interface Slicing algorithm that mines change information from two versions of an evolving distributed system. This article applies change mining and evolution mining to evolving distributed systems.

Together, these contributions pave the way for a new range of specification-driven applications in areas such as code generation and testing.Ĭhangeability and evolvability analysis can aid an engineer tasked with a maintenance or an evolution task. Finally, we present a tool suite including an editor, a parser, an OAS extension, a constraint programming-aided library, and a test suite supporting IDL specifications and their analyses. Specifically, we present a catalogue of seven analysis operations on IDL documents allowing to compute, for example, whether a given request satisfies all the dependencies of the service. Then, we propose a mapping to translate an IDL document into a constraint satisfaction problem (CSP), enabling the automated analysis of IDL specifications using standard CSP-based reasoning operations. We first present a domain-specific language, called Inter-parameter Dependency Language (IDL), for the specification of dependencies among input parameters in web services. In this article, we present an approach for the specification and automated analysis of inter-parameter dependencies in web APIs. Unfortunately, current specification languages for web services like the OpenAPI Specification (OAS) provide no support for the formal description of such dependencies, which makes it hardly possible to automatically discover and interact with services without human intervention. Web services often impose inter-parameter dependencies that restrict the way in which two or more input parameters can be combined to form valid calls to the service.
