28、 the present document. Foreword 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 pre

29、sent 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: “TTCN-3 Runtime Interface (TRI)“; Part 6: “TTCN-3 Control Interface (TCI)“;

30、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“. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“,

31、“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 “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI ES 202 786 V1.4.1 (2017-05) 6 1 Scope The present

32、document defines the “Continuous Signal support“ 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 (incl

33、uding supplementary services), module testing, testing of 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

34、 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 usages of TTCN-3.

35、 This package defines concepts for testing systems using continuous signals as opposed to discrete messages and the characterization of the progression of such signals by use of streams. For both the production as well as the evaluation of continuous signals the concept of mode is introduced. Also,

36、the signals can be processed as history-traces. Finally, basic mathematical functions that are useful for analyzing such traces are defined for TTCN-3. It is thus especially useful for testing systems which communicate with the physical world via sensors and actuators. While the design of TTCN-3 pac

37、kage 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 outside the scope of the present document. 2 References 2.1 Normative references References are
