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“

23、; 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: “The IDL to TTCN-3 Mapping“; Part 9: “Using XML schema with TTCN-3“; Part 10: “TTCN-3 Documentation Comment Specification“.

ETSI ETSI ES 202 782 V1.3.1 (2015-06) 6 1 Scope The present document defines the real time and performance testing support package of TTCN-3. TTCN-3 can be used for the specification of all types of reactive system tests over a variet

26、y 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

27、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

28、 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 of the core language with a number of

29、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 edition number or version number) or non-sp

ETSI ETSI ES 202 782 V1.3.1 (2015-06) 8 5 Package concepts for the core language 5.0 General Real-time systems have to respect special requirements for timing. Often functional requirements are directly connected to the timing of the messages and procedure call

45、s. Thus, checking the message values and the message order is not sufficient here. A test component shall be able to check whether a message has been received in time and shall be able to control the timing for the stimulation. Thus, a test language has to provide means to measure time, to specify t

46、ime points and time spans, to control the timing of the stimulation, and to calculate and compare time values. Moreover the test execution engine has to ensure that the specified actions (time measurement, timed stimulation) are executed correctly with respect to the required precision. To fulfil th

47、e requirements for testing real time system we define the following TTCN-3 core language extensions: A test system wide available test system clock, that allows the measurement of time during test case execution. Means to directly and precisely access the time points of the relevant interaction even

48、ts between the test system and the system under test. Real-time measurements at ports require additional resources (e.g. functionality that monitor ports and collect timestamps that describe the reception time of messages, calls, replies or exceptions) that may slow down the test execution. In order

49、 to avoid unnecessary delays at ports, such resources may only be provided when needed. An additional real-time clause for ports shall indicate the need for real-time measurement at a port. 5.1 The test system clock 5.1.0 General In RT TTCN-3 time progress is measured with a test system clock. The clock is initialized (set to 0.0) at the beginning of each test case execution and is available during the complete test run in each component. The clock values are represent
