5.1.2 Test strategy
As the base standard TS 183 004 [1] contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification TS 186 014-1 [10].

Figures 1 and 2 above show that there are 2 interfaces of the IWU (representing the SUT in the testing environment described in the present document): a SIP interface and an ISUP- or BICC interface. Since the ISUP and BICC protocols are very similar (the latter one being derived from ISUP), they are treated here as one...

5.1 Requirements and Test Purposes
For each test purpose there is a table defined in clause 6 of TS 186 009-2 [1]. The requirements applicable to this TP are given by a reference to RFC 3261 [17] (SIP) and TS 129 163 [4] or TS 129 527 [5] (ISUP). There are no explicit formulations of requirements. NOTE: During the ATS development comments have been made...

5.2.1 Test case grouping
The ATS structure defined in table 15 is based on the structuring of Test Purposes in clause 5 of TS 186 009-2 [1]. The group names in columns 1 to 3 of table 15 are those assigned in the ATS; they are based on the names provided in clause 5 of TS 186 009-2 [1], but use the naming conventions defined for the ATS (see c...

The test case names are built up according to the following scheme: <"TC">"_"<Group index>"_"<TC number> where: a) double quotes (") are used to enclose literal strings; b) <Group path index> is the 3-digit number in column 4 of table 15 (which uniquely identifies the path of groups/subgroups); ETSI ETSI TS 186 009-3 V...

5.3.1 ATS Library
For this interworking ATS there are 2 applicable base protocols: a) SIP protocol (RFC 3261 [17]); and b) ISUP protocol (ITU-T Recommendation Q.76n series [13] to [16], plus associated standards for supplementary services, etc.). Since e.g. the data structures of these 2 base protocols are independent, and other objects...

5.3.2.1 General
TTCN-3 as defined in ES 201 873-1 [8] is used as ATS specification language. A number of requirements have been identified for the development and production of the TTCN-3 specification for the SIP/ISUP Interworking ATS: • Top-down design. • A uniquely defined testing architecture and test method.

5.3.2.2 TTCN-3 naming conventions
Like in other software projects using a programming language, the use of naming conventions supports or increases: a) the readability; b) the detection of semantic errors; c) the shared work of several developers; d) the maintainability. The naming conventions applied to the SIP/ISUP Interworking ATS are based on the f...

5.3.2.4 Additional concepts and conventions
IMS procedures and tests requires the inclusion of user identification and network address information in SIP messages. Since this information depends on the specific SUT at hand it is defined using module parameters. Due to the big amount of such parameters a profile concept have been introduced for particular paramet...

No TTCN-3 control part has been defined for this test suite. If applicable PICS information is evaluated at the begining of each test case definition using an "if" statement. Log information is provided in case that a test has not been executed due to PICS setting violation. ETSI ETSI TS 186 009-3 V2.1.1 (2009-09) 28

5.3.2.6 TTCN-3 comment tags
Any TTCN-3 definition in the Test Suite Repository or Library should contain embedded comment tags. These comment tags can be used by tools to extract information from the TTCN-3 code to create, for example, a HTML-based reference documentation. Comment tags which cover one or more lines should be specified using block...
