The tree is of rank 2 with the
21、first rank a functional area and the second rank is the standard ISO conformance test categories. 4.2 Test groups 4.2.1 Introduction The test suite has a total of three levels. The first level is the root. The second level separates the root into various functional areas. The third level is the stan

ETSI EN 302 637-3 1 does not use the finite state machine concept. As consequence,
27、the test purposes use a generic “Initial State“ that corresponds to a state where the IUT is ready for starting the test execution. Furthermore, the IUT shall be left in this “Initial State“, when the test is completed. Being in the “Initial State“ refers to the starting point of the initial device
28、configuration. There are no pending actions, no instantiated buffers or variables, which could disturb the execution of a test. 5.1.4 Sources of TP definitions All TPs are specified according to ETSI EN 302 637-3 1. 5.1.5 Mnemonics for PICS reference To avoid an update of all TPs when the PICS docum
