18、TSI Technical Committee Methods for Testing and Specification (MTS). The present document relates to the 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:
19、“TTCN-3 Runtime Interface (TRI)“; Part 6: “TTCN-3 Control Interface (TCI)“; Part 7: “Using ASN.1 with TTCN-3“; Part 8: “The IDL to TTCN-3 Mapping“; Part 9: “Using XML schema with TTCN-3“; Part 10: “TTCN-3 Documentation Comment Specification“; Part 11: “Using JSON with TTCN-3“.

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 interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for t
21、he expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI ES 203 022 V1.1.1 (2017-07) 5 1 Scope The present document defines the support of advance matching of TTCN-3. TTCN-3 can be used for the specification of all types
22、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), module testing, testing of OMG CORBA based platforms, APIs, etc. TTCN-3 is not restricted t
23、o 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 protocols is outside the scope of the present document. TTCN-3 packages are intended to define
24、 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. While the design of TTCN-3 package has taken into account the consistency of a combined usage
25、of the core language with a number of packages, the concrete usages of and guidelines for this package in combination with other packages is outside the scope of the present document. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or editi

ETSI ETSI ES 203 022 V1.1.1 (2017-07) 7 5 Package Concepts
39、for the Core Language 5.0 General This package defines advanced matching mechanisms for TTCN-3, i.e. new matching mechanisms which go beyond the matching mechanisms defined in ETSI ES 201 873-1 1. This package realizes the following concepts: Dynamic matching allows to specify matching in a function
40、-like fashion, i.e. statement blocks and functions can be used to define matching. Templates with variable bindings ease the retrieval field values of received messages and signatures. For this the “-“ symbol is used to denote a value assignment to a variable or an out parameter in the scope of a te
41、mplate definition in case of a successful template matching. The additional logical operators conjunction, implication, exclusion and disjunction allow the combination matching mechanisms for advanced matching. Repetition allows to match repetitions of a sub-sequence templates inside values of a cer
42、tain type. Restrictions for the omit symbol and templates with restriction omit are relieved allowing omit symbols and templates with restriction omit as operands for the equality operator. 5.1 Dynamic Matching A dynamic matching is a special matching mechanism. Similar to other matching mechanisms,
43、 it can be considered as a Boolean function that indicates successful matching for the value to be matched by returning the value true and unsuccessful matching by returning the value false. Syntactical Structure dynamic (StatementBlock | FunctionRef) Semantic Description The StatementBlock shall re
44、turn a value of type boolean. The value to be matched is referenced by the special keyword value. When applying this matching mechanism to a value, the StatementBlock is executed and if and only if the execution returns true, the dynamic matching function matches. Unsuccessful matching shall return
45、false. A dynamic matching function can only be used in the context of a template, the value expression inside the StatementBlock shall have the same type as the whole template. The notation dynamic FunctionRef denotes a shorthand for the special case dynamic return FunctionRef(value) where FunctionR
46、ef is a reference to a Boolean function with a single parameter compatible with the templates type. Here, the type of the parameter of the referenced function determines the type context, if this templates place of usage does not provide a type context. Restrictions a) The dynamic matching syntax sh
47、all only be used in a typed context. b) The StatementBlock shall compute a value of type boolean. c) The StatementBlock shall be deterministic and side-effect free and follow the restrictions of clause 16.1.4 of ETSI ES 201 873-1 1. d) The StatementBlock shall not use variables that are declared out
48、side of the StatementBlock. e) The StatementBlock shall not use inout or out parameters. ETSI ETSI ES 203 022 V1.1.1 (2017-07) 8 f) Only if the dynamic matching syntax appears on the right-hand-side of a parameterized template definition, the formal in parameters of that definition may be referenced
49、 inside the StatementBlock. All other formal in parameters shall not be used by the StatementBlock. EXAMPLE: type record of integer Numbers; template Numbers mw_sorted := dynamic / value is of type Numbers for (var integer v_i := 1; v_i valuev_i) return false return true; / mw_sorted(v_recInt) matches all values of type Numbers / if elements of v_recInt do not break an ascending order type record Coordinate float x, float y ; external function fx_distance(Coordinate
