17、TSI Technical Committee Methods for Testing and Specification (MTS). Introduction The encouragement of the European Commission for the adoption and promotion of generic test frameworks for the validation of standards based on multiple stacks including middleware provides evidence that successful tes
18、ting as well as interoperability are key factors to enable the use of new technologies providing all benefits attached to them including competitiveness and innovation. However, technologies are becoming more complex, collaborative and inter-dependant. Therefore, methodologies and approaches for ens
19、uring interoperability need to be innovative and consider new evolving challenges such as the distribution of components and their remote access in an embedded environment. This guide adapts and presents a solid and proven method to these new challenges. The current and future e-communication market
20、 can be described as a convergent multimedia market with an increasingly complex structure. Within the present competitive environment, the risk of non-interoperability is increasing due to a fast evolution of technology and the use of non-open standards. The main purpose of standardization is to en
21、able interoperability in a multi-vendor, multi-network, multi-service environment. The absence of interoperability should not be the reason why final services for which there is great demand do not come into being. Interoperability test suites are usually based on a basic simple idea: key reference
22、points (interfaces) are checked while end-to-end interoperability tests are executed to observe if the message flow conforms to the flows mandated by standards. Each interoperability test suite is compounded by several tests. During interoperability test events, e.g. ETSI Plugtests, systems develope
23、d by different vendors are paired up to execute an agreed set of interoperability tests in test sessions. In such scenarios, automation could help to achieve dramatic time savings. The purpose of testing automation is to reduce time for testing and to avoid repetitive activities which involve a lot
24、of human specialist resources. Automation allows reducing manual interaction related to all the test phases: test execution, trace and message analysis, and reporting. Furthermore, testing automation increases traceability and reliability while it reduces risk of human error. Testing automation help
25、s to assure that the correct evaluation of all the procedures and the parameters foreseen in the testing specification is performed for each test. The process to automate interoperability testing i.1 is based on the test description and on the test architecture where system developers should find th
26、e unambiguous expected test behaviour, the configuration preconditions, and the network configuration required. The present document collects example realizations of TTCN-3 based test systems for automated interoperability testing. It provides example applications of the ETSI framework and methodolo
27、gy for automated interoperability testing. ETSI ETSI TR 102 788 V1.1.1 (2010-01) 61 Scope The present document presents the application of the generic framework and methodology for automated interoperability testing. More specifically, it presents its application to the interoperability testing of I
28、P Multimedia Subsystem (IMS) core networks. It includes test architecture, codec and adapter requirements as well as a TTCN-3 test suite that can be used in the context of interoperability events 2 References References are either specific (identified by date of publication and/or edition number or
