20、1.1.1 (2011-03)61 Scope The present document contains the Abstract Test Suite (ATS) for Geonetworking Basic Transport Protocol (BTP) as defined in TS 102 636-5-1 1 in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 5. The objective of th

21、e present document is to provide a basis for conformance tests for Geonetworking Basic Transport Protocol (BTP) equipment giving a high probability of inter-operability between different manufacturers equipment. The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 2 and ISO/IE

22、C 9646-2 3) as well as the ETSI rules for conformance testing (ETS 300 406 6) are used as a basis for the test methodology. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

The test system will simulate valid and invalid protocol behaviour, and will analyse the reaction of the IUT. ETSI ETSI TS 102 870-3 V1.1.1 (2011-03)8SUT Test System ITS-G5 IUT BTP ITS-G5 Lowe

In this configuration, the tester simulates one ITS station implementing the BTP protocol. 4.3 Test ar

35、chitecture This test specification implements the general TTCN-3 test architecture described in EG 202 798 i.1, clauses 6.3.2 and 8.3.1. Figure 2 shows the test architecture used in for the BTP ATS. The BTP test component requires using only the Main Test Component (MTC). The MTC communicates with t

36、he BTP SUT over the btpPort. The btpPort port is used to exchange BTP protocol messages between the BTP test component and the BTP IUT. The Upper tester entity in the SUT enables triggering BTP functionalities by simulating primitives from application or LDM entities. It is required to trigger the B

37、TP layer in the SUT to send BTP messages, which are resulting from upper layer primitives. Furthermore, receiving BTP messages may result for the BTP layer in sending primitives to the upper layer (sending Data to Facilities Layers for instance).

41、est Purposes This clause gives a list of TP, which are not implemented in the ATS due to the chosen ATM or other restrictions. Table 1: Untestable TP Test purpose Reason None 6 ATS conventions The ATS conventions are intended to give a better understanding of the ATS but they also describe the conve

42、ntions made for the development of the ATS. These conventions shall be considered during any later maintenance or further development of the ATS. The ATS conventions contain two clauses, the testing conventions and the naming conventions. The testing conventions describe the functional structure of

43、the ATS. The naming conventions describe the structure of the naming of all ATS elements. To define the ATS, the guidelines of the document ETS 300 406 6 was considered. 6.1 Testing conventions 6.1.1 Testing states 6.1.1.1 Initial state All test cases start with the function f_prInitialState. This f

44、unction brings the IUT in an “initialized“ state by invoking the upper tester primitive UtInitialize. 6.1.1.2 Final state All test cases end with the function f_poDefault. This function brings the IUT back in an “idle“ state. As no specific actions are required for the idle state in the base standar

45、d, the function f_ poDefault does not invoke any action. As necessary, further actions may be included in the f_poDefault function. 6.2 Naming conventions This test suite follows the naming convention guidelines provided in the EG 202 798 i.1. 6.2.1 General guidelines The naming convention is based

46、on the following underlying principles: in most cases, identifiers should be prefixed with a short alphabetic string (specified in table 2) indicating the type of TTCN-3 element it represents; suffixes should not be used except in those specific cases identified in table 7; prefixes and suffixes sho

47、uld be separated from the body of the identifier with an underscore (“_“); EXAMPLE 1: c_sixteen, t_wait. only module names, data type names and module parameters should begin with an upper-case letter. All other names (i.e. the part of the identifier following the prefix) should begin with a lower-c

48、ase letter; ETSI ETSI TS 102 870-3 V1.1.1 (2011-03)11 the start of second and subsequent words in an identifier should be indicated by capitalizing the first character. Underscores should not be used for this purpose. EXAMPLE 2: f_initialState. Table 2 specifies the naming guidelines for each elemen

49、t of the TTCN-3 language indicating the recommended prefix, suffixes (if any) and capitalization.
