14、 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 Behavio

15、ur (BV); - 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-REP1 Direct Mode Call Control (DMOMSREPl-DMCC) Circuit mode (CM) Capability tests (CA) Vali

18、st groups: CA, BV and TI. The second level of the test subgroups is a division of protocol requirements into functional entities.

The V

20、alid 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 thoroughly as possible the various functions of the protocol. Dif

21、ferent 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.

As the protocol has different options, as for instance the use of presence check or the absence of presence check, there are several ways to rea

28、ch a given state. The preamble has to be chosen according to the IUT capabilities and the implemented options.

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 purposes

42、, these complex selection expressions are replaced by generic names which are defined here, and which represent by definition the selection expression themselves.
