ETSI ETSI TS 102 868-3 V1.3.1 (2015-07)6 1 Scope The present document contains the Abstract Test Suite (ATS) for Co-operative Awareness Basic Service (CA) as defined in ETSI EN 302 637-2 1 in compliance with the relevant requirements and in accordance with
23、 the relevant guidance given in ISO/IEC 9646-7 5. The objective of the present document is to provide a basis for conformance tests for Co-operative Awareness Basic Service (CA) equipment giving a high probability of interoperability between different manufacturers equipment. The ISO standard for th
24、e methodology of conformance testing (ISO/IEC 9646-1 2 and ISO/IEC 9646-2 3) as well as the ETSI rules for conformance testing (ETSI ETS 300 406 6) are used as a basis for the test methodology. 2 References 2.1 Normative references References are either specific (identified by date of publication an

40、l tester The abstract protocol tester used by this test suite is described in figure 1. The test system will simulate valid and invalid protocol behaviour, and will analyse the reaction of the IUT. Figure 1: Abstract protocol tester - CA 4.2 Test Configuration This test suite uses a unique test conf
41、iguration in order to cover the different test scenarios. In this configuration, the tester simulates one ITS station implementing the CAM protocol. 4.3 Test architecture The present document implements the general TTCN-3 test architecture described in ETSI EG 202 798 i.1, clauses 6.3.2 and 8.3.1. F
42、igure 2 shows the test architecture used for the CA ATS. The CA test component requires using only the Main Test Component (MTC). The MTC communicates with the CA SUT over the camPort. The camPort is used to exchange CA protocol messages between the CA test component and the CA IUT. ETSI ETSI TS 102
43、 868-3 V1.3.1 (2015-07)9 The Upper tester entity in the SUT enables triggering CA functionalities by simulating primitives from application or LDM entities. It is required to trigger the CA layer in the SUT to send CA messages, which are resulting from upper layer primitives. Furthermore, receiving
44、CA messages may result for the CA layer in sending primitives to the upper layer (sending Data to LDM for instance). Figure 2: Test system architecture 4.4 Ports and ASPs (Abstract Services Primitives) 4.4.1 Introduction Two ports are used by the CA ATS: The camPort, of type CamPort. The utPort, of
45、type UpperTesterPort. 4.4.2 Primitives of the camPort Two types of primitives are used in the camPort: The CamInd primitive used to receive messages of type CamPdu. The CamReq primitive used to send messages of type CamPdu. ETSI ETSI TS 102 868-3 V1.3.1 (2015-07)10 These two primitives use the CamPd
46、u type, which is declared in the CAM.asn ASN.1 module, following the ASN.1 definition from ETSI EN 302 637-2 1. CamPdu := SEQUENCE header ItsPduHeader, cam CoopAwareness 4.4.3 Primitives of the utPort This port uses two types of primitives: The UtInitialize primitive used to initialize IUT. The UtTr
47、igger primitive used trigger upper layer events in IUT. 5 Untestable Test Purposes Table 1 gives a list of TPs, which are not implemented in the ATS due to the chosen ATM or other restrictions.

48、ATS 6 ATS conventions 6.1 Introduction The ATS conventions are intended to give a better understanding of the ATS but they also describe the conventions made for the development of the ATS. These conventions shall be considered during any later maintenance or further development of the ATS. The ATS
49、conventions contain two clauses, the testing conventions and the naming conventions. The testing conventions describe the functional structure of the ATS. The naming conventions describe the structure of the naming of all ATS elements. To define the ATS, the guidelines of the document ETSI ETS 300 406 6 were considered. 6.2 Testing conventions 6.2.1 Testing states 6.2.1.1 Initial state All test cases start with the function f_prInitialState. This function brings the IUT in an “initialized“ state by inv
