Introduction In response to EC
22、 mandate M/453 i.10, ETSI Technical Committee (TC) ITS has standardized base and test specifications for ITS protocols. In a next step a prototype TTCN-3 test system was built and validated. The present document describes the design and validation of the prototype TTCN-3 test system. The action desc
23、ribed in the present document has supported the implementation of ITS standards by: Making available validated and standardized test specifications and thus enabling the application of reliable certification schemes. Executing conformance validation framework against real Implementations Under Test
24、(IUTs) from industry and thus providing these companies a conformance assessment of their implementations. During the lifetime of this action, the conformance validation framework was as well provided at ITS Cooperative Mobility Services Interoperability events. Releasing all software as open source
25、 and thus allowing industry to build and run their own conformance validation framework. ETSI ETSI TR 103 099 V1.4.1 (2017-03) 6 1 Scope The present document provides a description of the architecture of the ITS conformance validation framework, including definition of the test environment, codec an
26、d test adapter. It provides, as well, all the necessary source code to build and run the ITS conformance validation framework. The ITS conformance validation framework integrates the test suites ETSI TS 102 871-3 i.4, ETSI TS 102 868-3 i.5, ETSI TS 102 869-3 i.6, ETSI TS 102 870-3 i.7, ETSI TS 102 8

43、d requirements The purpose of the ITS test platform is to provide a reliable set of software and hardware equipments that can be used to validate TTCN-3 abstract test suites (ATS) developed in ETSI. The architecture of this test platform has been designed with respect to the following constraints: t
44、o be compatible with the requirements expressed in the validation handbook (ETSI EG 201 015 i.2); to be independent of the platform used to implement the test system; to be independent of the TTCN-3 tool provider; to be configurable and customizable; to provide tools and well defined interfaces to s
45、ystem under test (SUT), allowing test automation; to be easily extensible for future ITS protocols; to provide generic components that can be reused in other test platforms. In order to ensure independence of hardware platforms, all software pieces running on the test platform have been implemented
46、using Java language, using generic and widely used libraries. Test tool independence has been achieved by isolating the tool specific interfaces from core functionalities of the platform. Adapting the current platform to a different test tool would only require the implementation of a very simple pi
47、ece of software mapping tool-specific functions to generic functions defined in this project. In addition, great care has been taken to separate ITS specific functionalities from generic test platform tasks in order to provide a maximum number of reusable components for future test platforms. 4.2 Ge
48、neral architecture Typically a TTCN-3 test platform is composed of four different components: The TTCN-3 test tool providing necessary software to execute the abstract test suites. The hardware equipment supporting TTCN-3 test execution and adaptation to SUTs. The codecs which convert protocol messa
49、ges into their abstract TTCN-3 representation. The Test Adapter (TA) implementing interfaces with the device under test. The interaction of these components is described in figure 1. ETSI ETSI TR 103 099 V1.4.1 (2017-03) 9 Figure 1: General architecture The TTCN-3 test tools are usually provided by commercial companies and their description is out of the scope of the present document.
