15、) 4 4.1 Test Suite Structure (TSS) DMCC layer test groups The first level separates the DMCC layer (or layer 3) in different protocols (Circuit mode, Short Data Service). Next level splits protocol testing into functional test groups according to the type of testing: Capability test (CA), Valid Beha
16、viour (BV) and Timer tests (TI). Further level classifies the possible operations in each protocol condition or state. The following list defines the DMCC layer test group names and identifiers used for those: - MS-REP2 Direct Mode Call Control (DMOMSREP2OMCC) - Circuit mode (CM) - Capability tests

19、eparates the MAC test suite in functional test groups: CA, BV and TI. The second level of the test subgroups is a division of protocol requirements into functional entities. The following list defines the MAC layer test group names and identifiers: - MS-REP2 MAC layer (DMOMSREP2MAC) - Capability tes

21、he additional capabilities claimed in the PICSPIXIT. The Valid Behaviour (BV) group tests an IUT in response to valid behaviour of the test system. “Valid“ means that a test event is syntactically and contextually correct. All test cases in the valid behaviour group are intended to verify as thoroug
22、hly as possible the various functions of the protocol. Different timers are defined to supervise the various state transitions. The Timer (TI) test group is intended to verify that the IUT is reacting properly to an expiry of one of the timers or to a counter mismatch. ETSI 10 ETSI EN 300 394-4-1 1
23、V1.l.l (2001 -01) TP-Name The TP name is a unique identifier, specified according to the TP naming conventions defined in the clause below. (it is also the name of the corresponding test case) 5 Introduction to Test Purposes (TPs) The test purposes for DMCC layer and MAC layer are defined in clause

28、 Table 1 The preambles and postambles are described using MSCs and are shown in the following clauses. 5.1.2 Preamble descriptions Preambles are used to bring the IUT from the idle state to the state where the test takes place. As the protocol has different options, as for instance the use of presen
29、ce check or the absence of presence check, there are several ways to reach a given state. The preamble has to be chosen according to the IUT capabilities and the implemented options.

37、 reflect the capabilities supported or not by the implementation under test. It appears that some selection expressions are quite complex, mainly the ones used for the MAC layer test suite, as they are based on a rather long combination of PICS statements. To ease the readability of the test purpose
38、s, these complex selection expressions are replaced by generic names which are defined here, and which represent by definition the selection expression themselves.
