12、TSS) including its subgroups defined for conformance testing. Table 1 Root Group category BTP Packet Generation BTP-A Valid behaviour Packet Generation BTP-B Valid behaviour Packet Processing Valid behaviour 4.2 Test groups The test suite has a total of three levels. The first level is the root. The

13、 second level separates the root into various functional areas. The third level is the standard ISO conformance test categories. 4.2.1 Root The root identify the Geonetworking Basic Transport Protocol (BTP) given in TS 102 636-5-1 1. 4.2.2 Groups This level contains three functional areas identified

14、 as: Packet Generation BTP-A, Packet Generation BTP-B and Packet processing. 4.2.3 Categories This level contains the standard ISO conformance test categories limited to the valid behaviour and the invalid behaviour. 5 Test Purposes (TP) 5.1 Introduction 5.1.1 TP definition conventions The TPs are d

Reference The reference indicates the sub-clauses of the reference standard specifications in which the conformance requirement is expressed. PICS Selection Reference to the PICS statement involved for selection of the TP. Contains a Boolean ex

17、pression. TP Behaviour Initial conditions The initial conditions defines in which initial state the IUT has to be to apply the actual TP. In the corresponding Test Case, when the execution of the initial condition does not succeed, it leads to the assignment of an Inconclusive verdict. Expected beha

18、viour(TP body) Definition of the events, which are parts of the TP objective, and the IUT are expected to perform in order to conform to the base specification. In the corresponding Test Case, Pass or Fail verdicts can be assigned there. Final conditions Definition of the events that the IUT is expe

19、cted to perform or shall not perform, according to the base standard and following the correct execution of the actions in the expected behaviour above. In the corresponding Test Case, the execution of the final conditions is evaluated for the assignment of the final verdict. 5.1.2 TP Identifier nam
