17、ord This ETSI Standard (ES) has been produced by ETSI Technical Committee Methods for Testing and Specification (MTS). The use of underline (additional text) and strike through (deleted text) highlights the differences between base document and extended documents. The present document relates to the
18、 multi-part standard ETSI ES 201 873 covering the Testing and Test Control Notation version 3, as identified below: Part 1: “TTCN-3 Core Language“; Part 4: “TTCN-3 Operational Semantics“; Part 5: “TTCN-3 Runtime Interface (TRI)“; Part 6: “TTCN-3 Control Interface (TCI)“; Part 7: “Using ASN.1 with TT
19、CN-3“; Part 8: “The IDL to TTCN-3 Mapping“; Part 9: “Using XML schema with TTCN-3“; Part 10: “TTCN-3 Documentation Comment Specification“. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be
20、 interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI ES 202 784 V1.5.1 (2015-06) 5 1 Scope The present document defines the Advance
21、d Parameterization package of TTCN-3. TTCN-3 can be used for the specification of all types of reactive system tests over a variety of communication ports. Typical areas of application are protocol testing (including mobile and Internet protocols), service testing (including supplementary services),
22、 module testing, testing of CORBA based platforms, APIs, etc. TTCN-3 is not restricted to conformance testing and can be used for many other kinds of testing including interoperability, robustness, regression, system and integration testing. The specification of test suites for physical layer protoc
23、ols is outside the scope of the present document. TTCN-3 packages are intended to define additional TTCN-3 concepts, which are not mandatory as concepts in the TTCN-3 core language, but which are optional as part of a package which is suited for dedicated applications and/or usages of TTCN-3. This p
24、ackage defines: Value parameters of types. Type parameterization. While the design of TTCN-3 package has taken into account the consistency of a combined usage of the core language with a number of packages, the concrete usages of and guidelines for this package in combination with other packages is
25、 outside the scope of the present document. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

37、ibility The package presented in the present document is identified by the package tag: “TTCN-3:2014 Advanced Parameterization“ - to be used with modules complying with the present document. NOTE: This version of the package only extends the previous versions, identified with the package tag “TTCN-3
38、:2009 Advanced Parameterization“, with the option of parameterizing objects - in addition to types - also with signatures. For this reason, modules not containing a formal or actual parameter of the kind signature are compatible with both versions. For an implementation claiming to conform to this p
39、ackage version, all features specified in the present document shall be implemented consistently with the requirements given in the present document, in ETSI ES 201 873-1 1 and in ETSI ES 201 873-4 2. The package presented in the present document is compatible to: ETSI ES 201 873-1 1, version 4.5.1;
40、 ETSI ES 201 873-4 2, version 4.4.1; ETSI ES 201 873-5 3, version 4.5.1; ETSI ES 201 873-6 4, version 4.5.1; ETSI ES 201 873-7 5, version 4.5.1; ETSI ETSI ES 202 784 V1.5.1 (2015-06) 7 ETSI ES 201 873-8 8, version 4.5.1; ETSI ES 201 873-9 9, version 4.5.1; ETSI ES 201 873-10 6, version 4.5.1. If lat
41、er versions of those parts are available and should be used instead, the compatibility to the package presented in the present document has to be checked individually. 5 Package concepts for the core language 5.1 Extension to ETSI ES 201 873-1, clause 4 (Introduction) The present package adds the fo

Clause 5.4.1.1 Formal parameters of kind value In addition to the existing rules, TTCN-3 supports value parameterizations as follows: the value parameters of user-defined types shall be in parameters; the language element signature does not support static value parameterization.
