40、 and contents of the protocol messages allows to test both valid and invalid behaviour. Figure 6.1-1: Conformance testing Conformance test specifications should be produced following the methodology described in ISO/IEC 9646-1 i.2. In summary, this methodology begins with the collation and categoriz

41、ation of the features and options to be tested into a tabular form which is normally referred to as the “ Implementation Conformance Statement“ (ICS). All implemented capabilities supported by the Implementation Under Test (IUT) are listed by the implementer in the ICS, so that the tester knows whic

42、h options have to be tested. This ensures that complete coverage is obtained. The next step is to collect the requirements from the specification that is tested. For each requirement, one or more tests should be identified and classified into a number of groups which will provide a structure to the

43、overall test suite (TSS). A brief Test Purpose (TP) should then be written for each identified test and this should make it clear what is to be tested but not how this should be done. Although not described or mandated in ISO/IEC 9646-1 i.2, in many situations (particularly where the TPs are complex

44、) it may be desirable to develop a Test Description (TD) for each TP. The TD describes in plain language (often tabulated) the actions required to reach a verdict on whether an implementation passes or fails the test. Finally, a detailed Test Case (TC) is written for each TP. In the interests of tes

45、t automation, TCs are usually combined into an Abstract Test Suite (ATS) using a specific testing language such as TTCN-3. The TCs in the ATS are then “Verified“ against a number of IUTs for correct operation according to some agreed procedures, before being released for use by the industry. An Impl

46、ementation eXtra Information for Test (IXIT) proforma associated to the ATS, should be produced in supplement of the ICS document and Test Cases to help to execute Protocol conformance testing using oneM2M dedicated test equipment. In summary, the oneM2M Conformance Testing methodology consists of:

47、Selection of Implementations Under Test (IUT). Identification of reference points. Development of test specifications, which includes: - Development of “Implementation Conformance Statements“ (ICS), if not already provided as part of the base standard. - Development of “Test Suite Structure and Test

48、 Purposes“ (TSS identification of the implementation; identification of the ; global statement of conformance Part of an example ICS table can be found in Annex A.1. 6.3.2 Test Suite Structure - invalid behaviour test; - timer test; - etc. Usually the identification of the different functional group

49、s of procedures leads to the definition of the top levels of the TSS. Then further levels at the bottom of the TSS is used to group test purposes belonging to the same type of test. Table 6.3.2.2-1 shows an example of a two level TSS used in the TSS square4 the expected behaviour; square4 the final conditions. The prose describing the test behaviour (including initial and final conditions) should follow some rules, as for instance the use of reserved keywords and syntax.
