"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

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 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

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 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

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-like fashion, i.e. statement blocks and functions

• 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

• Additional logical operators: conjunction, implication, exclusion and disjunction allow the combination

• Repetition: allows to match repetitions of a sub-sequence templates inside values of a certain type.

• Restrictions for the omit symbol and templates with restriction omit are relieved allowing omit symbols and

A dynamic matching is a special matching mechanism. Similar to other matching mechanisms, it can be considered as a

Boolean function that indicates successful matching for the value to be matched by returning the value true and

The StatementBlock shall return 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 false.

A dynamic matching function can only be used in the context of a template, the value expression inside the

The notation @dynamic FunctionRef denotes a shorthand for the special case @dynamic { return

FunctionRef(value) } where FunctionRef is a reference to a Boolean function with the first parameter compatible

with the template's type. If the function contains more than one parameter, all parameters following the first one shall

have a default value. The type of the first formal parameter of the referenced function provides the type context, if this

a) The dynamic matching syntax shall only be used when a type context (as defined in clause 3 of ETSI

c) The StatementBlock shall be deterministic and side-effect free and follow the restrictions of clause 16.1.4 of

d) The StatementBlock shall not use variables that are declared outside of the StatementBlock.

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 inside the StatementBlock. All other formal in

g) The FunctionRef shall not have a runs on clause and the StatementBlock shall not use any behaviour that

The possibilities to retrieve field values of received messages and signatures in ETSI ES 201 873-1 [1] are restricted

and cumbersome. To overcome this situation, this clause implements the definition of templates with variable bindings

that store the actual value matched by a template instance if the matching of all containing templates is successful. This

feature is implemented by using the "->" symbol for denoting a value assignment to a variable or an out parameter in

the scope of a template definition in case of a successful template matching. Such a value assignment can syntactically

be specified at all places where a template matching mechanism or a template reference is used in a template definition

In case of a successful template match, the value which matches the template can be assigned to a variable. This can be

If a template successfully matches a value and contains a value retrieval assignment for a TemplateInstance, then, if

during the matching process that TemplateInstance and all its containing TemplateInstances contribute to the successful

template match, the part of the value the TemplateInstance was matching is assigned to the VariableRef referenced in
