ETSI ETSI TS 102 950-3 V1.6.1 (2017-08)5 1 Scope The present document specifies the Abstract Test Suite (ATS) for the TTCN-3 conformance test suite, as defined in ETSI ES 201 873-1 1 in compliance with the relevant guidance given in the pro for

20、ma for TTCN-3 reference test suite ETSI TS 102 950-2 8. The objective of the present document is to provide a basis for conformance tests for TTCN-3 tools giving a high probability of standard conformance with respect to TTCN-3 tools from different vendors. In the present document only the core lang

21、uage features, specified in ETSI ES 201 873-1 1 have been considered but not the tool implementation (see i.1 and i.2), language mapping (see i.3, i.4 and i.5) and language extension (see e.g. i.6, i.7 and i.8) aspects. The test notation used in the ATS attached in a zipped file is in TTCN-3 and it

22、is part of the present document. Annex A provides the Tree and Tabular Combined Notation (TTCN-3) part of the ATS. Annex B provides the Partial Implementation Extra Information for Testing (PIXIT) pro forma of the ATS. 2 References 2.1 Normative references References are either specific (identified

23、by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies.

41、2 of ETSI TS 102 950-2 8, but use the naming conventions defined for the ATS (see clause 5.3.1.2). The test case identifier naming scheme differentiates between positive and negative tests as well as syntactical and semantics tests. Syntactical tests are tests that refer to annex A of ETSI ES 201 87

42、3-1 1. They include pure syntactical tests and tests regarding the static semantics to the degree of detail that annex A provides. Semantic tests are tests that refer to the checking of properties regarding the static and dynamic semantics of TTCN-3 according to the specific clauses of ETSI ES 201 8

43、73-1 1. Positive tests are tests that shall work with a standards compliant TTCN-3 tool. Negative tests are tests that shall not work with a standards compliant TTCN-3 tool. The test cases shall conform to the following correctness rules: Negative syntactic tests shall be correct with respect to the

44、 TTCN-3 BNF and the static semantics of TTCN-3, but violate only one specific TTCN-3 BNF rule or static semantic rule specified in annex A of ETSI ES 201 873-1 1. They shall not produce an ETS. Positive syntactic tests shall be correct with respect to the TTCN-3 BNF and the static semantics of TTCN-

45、3. They may produce an ETS and if it contains a control-part or a test case, it should be executed. Negative semantic tests shall be correct with respect to the TTCN-3 BNF and the static semantics of TTCN-3, but violate the semantics of one specific text clause of ETSI ES 201 873-1 1. They may produ

46、ce an ETS. If an ETS is produced and if it contains a control-part or a test case, it should be executed. Positive semantic tests shall be correct with respect to the TTCN-3 BNF, the static semantics of TTCN-3, and the respective text clauses of ETSI ES 201 873-1 1. They shall produce an ETS. If an

47、ETS is produced and if it contains a control-part or a test case, it should be executed. ETSI ETSI TS 102 950-3 V1.6.1 (2017-08)9 The test case identifiers and their group index do not imply the correct execution order of a TTCN-3 tool conformance test. Grouping and subgrouping in the ATS is realize
