ETSI ETSI TS 186 007-3 V3.1.1 (2012-01)51 Scope The present document specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma based on the Te
18、st Suite Structure and Test Purposes defined in TS 186 007-2 2. The test notation used in the ATS is TTCN-3 (see ES 201 873-1 7). The following test specification- and design considerations can be found in the body of the present document: the overall test suite structure; the testing architecture;
19、the test methods and port definitions; the test configurations; the design principles, assumptions, and used interfaces to the TTCN3 tester (System Simulator); TTCN styles and conventions; the partial PIXIT proforma; the modules containing the TTCN-3 ATS. Annex A provides the Partial Implementation
20、Extra Information for Testing (PIXIT) Proforma of the ATS. Annex B provides the Testing and Test Control Notation (TTCN-3) part of the ATS. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

30、ifies the path of groups/subgroups); c) is a running 3-digit decimal number, starting in each subgroup path with “001“. EXAMPLE: TC_CH_U01_001: i) the identifier has Group index “CH_U01“, i.e. it is in the subgroup having complete path: SupplementaryServices_CH/ServedUser/WithUPDATE; ii) the identif
31、ier is the first test case of this group/subgroup. ETSI ETSI TS 186 007-3 V3.1.1 (2012-01)8NOTE: This naming scheme provides a 1-1 correspondence of TP identifiers as defined in TS 186 007-2 2 and test case names. The TP identifier of TC_CH_U01_001 is TP CH_U01_001. 5.3 ATS specification framework 5
32、.3.1 ATS Library For this ATS the TTCN-3 library modules are basically organized as: 1) AtsCommon modules. 2) LibIms modules. 3) LibSip modules (RFC 3261 4). 4) LibCommon modules (taken from an improved version of TS 102 351 8). NOTE: Due to the common LibSip and LibIms library approach with some ot
33、her parallel running projects there is necessary to create tag version of all library modules. Table 2 shows the organization of the ATS as library of modules.

41、the use of TTCN-3 described in clause 5.3.2 of TS 102 790-3 3 applies.
