An execution system of distributed performance testing is designed in this paper, which provides a mechanism of node communication, test script deployment, test scheduling, execution-driving and test result collection in distributed environment. A workload model is established, by which testers can describe the performance testing requirement. A performance testing framework is given, which simulates user behaviors in real environment based on virtual users so as to generate workload from the system under test (SUT). It can control the execution of virtual users by TTCN-3 standard interface. After executing the performance testing, test report is generated by extracting log. A method of generating performance test-case is studied by reusing functional test scripts. By executing performance testing on an online bookstore, this paper demonstrates the availability of the method of reusing TTCN-3 functional test scripts and the capability of distributed performance testing system established.

A common conformance testing is needed before the modules equipped in the vehicle to ensure their design meet the standard requirements and capability to work together. In this paper SGSF-064-1 have been followed and its conformance testing items are described. SGSF-064-1 is the standard which provide communication interface for DC fast charging in Korea. We specially focused on the conformance testing when the vehicle is fully charged. We used TTC-3 language to perform simulation.

This paper describes a testing method about handover conformance and testing framework based on TTCN-3. In addition, the handover conformance testing process between the LTE and TD-SCDMA system is designed, and the testing flow chart and reports are generated by the TTWORKBENCH platform, finally this test system is verified. The results accord with the requirement of the 3GPP conformance testing.

This paper focuses on the terminal RRC connection establishment procedure, designs its message sequence chart (MSC), then write abstract test suits in TTCN-3 core language on TTworkbench test platform, generate GFT figure and compare it with the protocol specification, and complete conformance testing of RRC connection establishment procedure. At present, this scheme has been effectively verified in the project of TD-LTE TTCN extended test suite instrument development.

In order for the RRM conformance of implementation in TD-LTE system idle_state, taking inter-frequency cell reselection procedure as the point of penetration, a new testing scheme is designed by developing testing and test control notation version 3(TTCN-3) test case to verify the RRM conformance. Furthermore, the test case is operated on the TTworkbench developed by German Testing tech. It also generates test execution flow chart to check the RRM conformance of idle_state functions.

With 4G licenses issued in China, the RRM (Radio Resource Management) conformance test for TD-LTE system becomes a critical work. This paper will use TTCN-3 to achieve the corresponding test case in order to validate the protocol conformance in the measurement process of RRM in TD-LTE system. And it shows the method of implementation and generated GFT. The research work of this paper is supported by national science and technology major special "TD-LTE TTCN extension test set instrument development".
