37、stract protocol tester An abstract protocol tester (APT) is a process that provides behaviours for testing an IUT by emulating a peer IUT at the same layer, and enabling to address a single test objective. APTs used by the SmartAppliances test suite are described in figure 5.1-1. The test system wil

38、l simulate valid and invalid protocol behaviour, and will analyse the reaction of the IUT.

Three different lower layers ha

41、ve been specified corresponding to the binding protocols considered in oneM2M: HTTP, CoAP, MQTT or WebSocket. 5.2 Test Configuration This test suite uses a unique test configuration in order to cover the different test scenarios. In this configuration, the tester simulates a CSE on Mca interface as

42、defined in Test configuration 3 (CF03) in Figure 4.1-3. 5.3 Test architecture The approach for the implementation of an Abstract Protocol Tester selected in SmartAppliances follows the recommendation of the oneM2M Testing Framework defined in ETSI TS 118 115 5 where the TTCN-3 language and its archi

43、tecture are recommended. Following this recommendation the SmartAppliances tester architecture comprises a non-platform dependent Test Suite, and a platform dependent part.

It allows a complete decoupling between the test suite and the r

45、est of the test system. The test suite is composed of a complete set of test cases covering SmartAppliances requirements specified by ETSI TS 103 264 1 and ETSI TS 103 267 2. SmartAppliances System Adapter: this is the platform dependent part that includes adapters and codecs (out of the scope of th

46、e present document). This part of the architecture definition depends on the specific platform, operating system and test tool on which the tester is going to run. However, it can be implemented in a semi-independent manner, which will minimize the dependency to those elements. Figure 5.3-2 shows th

47、e SmartAppliances TTCN-3 test architecture design used for the SmartAppliances ATS. The Test Suite needs to interact with the System Adapter to implement the collection of TTCN-3 test cases that are intended to be used to test the SmartAppliances IUTs. The SmartAppliances TTCN-3 test cases implement

48、 the test algorithms specified in the TSS and 2) observe the test events received from the IUT. In TTCN-3 these two interfaces have been implemented through a logical TTCN-3 concept called port (mcaPort and mccPort respectively) which allows oneM2M message primitives exchange with the IUT.

49、 TS 103 268-4 V1.1.1 (2017-04)11 Figure 5.3-2: SmartAppliances Test Architecture The oneM2M primitive messages have been mapped into TTCN-3 structure. Through this mapping, the TTCN-3 is able to build and send these messages, as well as receive them via the mcaPort and mccPort. Additionally, the test cases are able to control and configure the test platform through a dedicated port called acPort. To build up a tester, the test platform shall be also developed (out of scope). This test platform is composed of
