19、service The test suite is structured as a tree with a first level defined as ERC-AP or ERC-MT representing the protocol group “DLC Error Control service for AP and DLC Error Control service for MT“. 4.2 Test groups The test groups are organized in three levels. The first level creates one protocol g

20、roup representing the protocol services. The second level separates the protocol services in functional modules. The last level in each branch contains one or more of the standard IS0 subgroups CA, BV, BI and BO. 4.2.1 Protocol groups The protocol groups identify the DLC Error Control service, as de

Initial condition. Stimulus. Expected behaviour. The TP Id is a unique identifier it shall be specified according to the

22、 TP naming conventions defined in the subclause below. The reference should contain the references of the subject to be validated by the actual TP (specification reference, clause, and paragraph). The condition defines in which initial state the IUT has to be to apply the actual TP. The stimulus def

23、ines the test event to which the TP is related. Definition of the events that are expected from the IUT to conform to the base soecification. 4.2.1 .I Transmission mode The Error Control service group is divided in three functional modules. The first functional module identifies acknowledge mode pro

24、cedures. The second functional module identifies repetition mode procedures. The last functional module identifies unacknowledge mode procedures. 4.2.2 Main test groups The main test groups are the capability group, the valid behaviour group, the invalid behaviour group and the inopportune behaviour

25、 group. 4.2.2.1 Capability (CA) tests This test sub group shall provide limited testing of the major IUT capabilities aiming to insure that the claimed capabilities are correctly supported, according to the PICS. 4.2.2.2 Valid Behaviour (BV) tests This test sub group shall verify that the IUT reacts

26、 in conformity with the EN, after receipt or exchange of valid Protocol Data Units (PDUs). Valid PDUs means that the exchange of messages and the content of the exchanged messages are considered as valid. 4.2.2.3 Invalid Behaviour (BI) tests This test sub group shall verify that the IUT reacts in co

27、nformity with the EN, after receipt of a syntactically invalid PDU. 4.2.2.4 Inopportune Behaviour (BO) tests This test sub group shall verify that the IUT reacts in conformity with the EN, after receipt of a syntactically correct PDU not expected in the actual message exchange. 5 Test Purposes (TP)
