ETSI ETSI TS 102 797-2 V1.2.1 (2014-06)64 Test suite structure In general, the conformance test system architecture presented in the ITS testing framework EG 202 798 i.1 extended as illustrated in figure 1 applies.

15、ture for SUTs Such SUTs which support the “ITS station-internal Management Communications Protocol“ (IICP) ISO 24102-4 1 may benefit from the conformance test system architecture illustrated in figure 2, where the access to the IUT is performed via remote access to the management SAPs applying IICP.
16、 This may be applied in general for all three ports (utPort, ltPort, cnPort). In case of testing IICP itself, the ITS lower layers end up in the ITS station-internal network.

19、strations given in the ITS testing framework EG 202 798 i.1. Nevertheless the principles outlined there apply also. The essential difference is, that the access from the “upper tester application“ and from the “ITS lower layers“ to the IUT is via the management SAPs. Note that for testing of FSAP an
20、d IICP, the ITS lower layers connect to the IUT via MF-SAP only. 5 Test purpose basics 5.1 TP definition conventions The TP definition is built according to the guidelines provided in the ITS testing framework EG 202 798 i.1, applying a formalized language with pre-defined keywords for the behaviour
21、 description. 5.2 TP identifier naming conventions The identifier of the TP is built according to tables 1 and 2 as recommended in the ITS testing framework EG 202 798 i.1.

The fields of this proforma as used in the present document are explained in table 3. Table 3: TP proform
26、a field description TP Header TP ID The TP ID is a unique identifier according to the TP naming conventions in tables 1 and 2. Test objective Short description of test purpose objective according to the requirements from the base standard. Reference The reference indicates the clauses of the referen
27、ce standard specifications in which the conformance requirement is expressed. PICS selection Reference to the PICS statement involved for selection of the TP. Contains a Boolean expression. May contain PICS acronyms specified in tables 4 and 5. This section is only used in case an optional or condit
28、ional behaviour needs to be selected. Mandatory behaviour is identified by an empty field. TP Behaviour Initial conditions (optional) The initial conditions define in which initial state the IUT has to be to apply the actual TP. In the corresponding “Test Case“ (TC), when the execution of the initia
29、l condition does not succeed, it leads to the assignment of an Inconclusive verdict. Expected behaviour (TP body) Definition of the events, which are parts of the TP objective, and the IUT are expected to perform in order to conform to the base specification. In the corresponding TC, “Pass“ or “Fail
30、“ verdicts can be assigned there. 5.6 PICS mnemonics The PICS mnemonics presented in tables 4 and 5 are used in the TP proforma.
