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 following list defines the MAC layer test group names and identifiers: - DM-REP1

19、MAC layer (DMO-DMREPlMAC) - Capability tests (CA) - Valid behaviour tests (BV) - Invalid behaviour tests (BI) - Timer tests (TI) 4.2 Test g roup descri pt ion Capability (CA) tests provide limited testing that the observable capabilities of the IUT are in accordance with the conformance requirements

20、 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 and contextually correct. All test cases in the valid behaviour group are intended to verify as t

21、horoughly 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. 5 Introduction to Test P
