Foreword This ETSI Standard (ES) has been produced by ETSI Technical Committee Methods for Testing

21、 and Specification (MTS). The present document relates to the multi-part deliverable 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

22、: “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“. NOTE: Part 2 is in status “historical“ and part 3 is no longer

23、 maintained. 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 the expression of provisions). “must“ and

24、 “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI ES 203 022 V1.2.1 (2018-05) 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 of reactive system tests over a variety

25、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 to conformance testing and can be used fo

26、r 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 additional TTCN-3 concepts, which are n

27、ot 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 of the core language with a number of pa

28、ckages, 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 edition number or version number) or non-spec

ETSI ETSI ES 203 022 V1.2.1 (2018-05) 7 5 Package Concepts for the Core Language 5.0 General This p

42、ackage 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-like fashion, i.e. statement blocks an

43、d 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 template definition in case of a success

44、ful template matching. 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 certain type. Restrictions for the omit sym

45、bol 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, it can be considered as a Boolean funct

46、ion 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 return a value of type boolean. The value

47、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 false. A dynamic matching function can o

48、nly 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 FunctionRef is a reference to a Boolean function

49、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 shall 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 8
