Next level splits protocol
14、testing into functional test groups according to the type of testing: Capability test (CA), Valid Behaviour (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
15、 for those: - MS-REP2 Direct Mode Call Control (DMOMSREP2-DMCC) - Circuit mode (CM) - Capability tests (CA) - Valid Behaviour tests (BV) - from Idle state(1D) - - - - from TX Reservation (TR) - from Idle state, channel busy (IB) from TX occupation State (TXO) from RX occupation State (RO) from RX Re

17、I TS 1 O0 394-4-1 1 V1.l.l (2000-1 O) 4.2 MAC layer test groups The first level of the MAC test groups separates 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 def
18、ines the MAC layer test group names and identifiers: - MS-REP2 MAC layer (DMOMSREP2MAC) - Capability tests (CA) - Valid behaviour tests (BV) - Channel usage (CU) - Signalling messages (SM) - Traffic mode (TM) - Timer tests (TI) 4.3 Test group description Capability (CA) tests provide limited testing
19、 that the observable capabilities of the IUT are in accordance with the conformance requirements and the 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 a
20、nd contextually correct. All test cases in the valid behaviour group are intended to verify as thoroughly 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 reacti
21、ng properly to an expiry of one of the timers or to a counter mismatch. ETSI 10 ETSI TS 1 O0 394-4-1 1 V1.l.l (2000-1 O) 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 In
22、troduction to Test Purposes (TPs) The test purposes for DMCC layer and MAC layer are defined in clause 6 of the present document. Each layer leads to Reference: reference to the clause number of specification EN 300 396-7 5 stating this conformance requirement. For example: EN 300 396-7 5, 6.2.5.1 a
23、 different test suite. Purpose Test description Pass criteria Selection Preamble Postamble 5.1 purpose of the test itself, indicating for example the test performed against a requirement of the protocol, described by this test purpose. Example: test of changeover initiated from RX reservation state
24、body of the test visible action to be observed at PCO to declare that the IUT passes the test and conforms to the specifications expression based on EN 300 396-8-4 6 PICS statements, used to select or deselect the corresponding test case according to the options of the implementation “None“ or name
25、of the preamble procedure bringing the IUT from idle state to the state required to run the test. For example: idleto-RX-reservation “None“ or name of the postamble to bring the IUT back to idle state, for example: RX-occupationto-idle Test purpose definition conventions 5.1.1 TPs descriptions Each
26、TP is described using text presented in a table. The table contains the following information: 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
27、the test takes place. 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 reach a given state. The preamble has to be chosen according to the IUT capabilities and the implemented options. ETSI 11 ETSI TS 1 O0 39

36、essions which 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
37、 test purposes, these complex selection expressions are replaced by generic names which are defined here, and which represent by definition the selection expression themselves.
