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 multi-part s
17、tandard 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 TTCN-3“; Part 8
18、: “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 interpreted

ETSI ETSI ES 202 789 V1.4.1 (2015-06) 51 Scope The present document defines the Extended TRI package
20、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
21、 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
22、 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 or in its interfaces TRI and TCI, but which are optional as part of a package which is suited for dedicated applications and/or usages of TTCN-3.
23、This package defines a more efficient handling of software values by a version of TRI, that does not use binary encoded messages for the communication with the SUT, but uses the values as they are; meaning e.g. that software objects or serialized data can be passed directly between the SUT and the T
24、E. 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 outside the scope of the present document. 2 References 2.1 No

ETSI ETSI ES 202 789 V1.4.1 (2015-06) 87 TRI extensions for the package 7.0 Introduction Historically, TTCN has been used to test communication protocols which typically use encoded messages. This has been r
45、eflected in the TRI SA and TCI CD design of TTCN-3 by encoding and decoding messages to and from bitstrings. However, TTCN-3 also supports signature-based communication for which the transformation of objects into bitstrings and vice versa is cumbersome. Furthermore, some protocols use also structur
46、ed messages for which the bitstring encoding is not helpful. Therefore, an alternative API is being defined in this extension package of TTCN-3 along which TTCN-3 values can be directly passed to/from the SUT. It is defined by redefining the operations in TRI SA and PA as follows. 7.1 Changes to cla
47、use 5.2 of ETSI ES 201 873-5, Error handling The SA or PA can in addition provide notifications about unrecoverable error situations by use of the operations xtriSAErrorReq and xtriPAErrorReq, respectively. 5.2.1 triSAErrorReq barb2right xtriSAErrorReq Signature void xtriSAErrorReq(in string message
48、, in any cause) In Parameters message A string value, i.e. the error phrase describing the problem. cause (Optional) cause of the problem. Return Value void Constraint Shall be called whenever an error situation has occurred in the SA with the exception of errors occurring when processing SA calls i
49、nitiated by the TE. These errors are reported in the operation return. The optional cause parameter can be used to provide information in addition to the error phrase in message. Effect The TE will be notified about an unrecoverable error situation within the SA and may forward the error indication to the test management. 5.2.2 triPAErrorReq barb2right xtriPAErrorReq Signature void xtriPAErrorReq(in string message, in any cause) In Parameters message A string value, i.e. the error phrase desc
