The Technology Research Of Test Environment Based On TCI Framework

TTCN-3 is a new test description language,it makes the use of a standardized test abstract description language possible in the area of the software development. This abstract description language can ensure that the same as we reuse the software as we reuse test, with a shorter time, less the cost of a higher quality of software products. TTCN-3 test system architecture and the previous test system were very different, it proposed based on the component of the concept of distributed testing system, test components distributed in different nodes can parallel implementate the testing.Through in-depth study TTCN-3 testing standards and on the basis of A0 the EU Go4IT stage realization of the project, from the development and application of TTCN-3, through the analysis of TTCN-3 ETSI standards and the single-node parallel test environment in the module structure and distribution, and combined with the characteristics and requirements of distributed test, established a distributed test environment needs, in particular,distributed test environment for the CH to the specific needs, This paper base on the realization of Go4IT project team T3RTS module and establish a reasonable distribution and module structure, on this basis, designed and implemented inter- test node to establish channels of communication mechanisms, gives a detailed design plan and the deployment of distributed testing environment. CH eventually formed a package of middleware functionality and verified.In this paper, the CH modules in full compliance with TTCN-3 standard defined by ETSI organization, all of the design and implementation on the realization of the principle of not to change the Go4IT stage of the project of the EU team A0, Seamlessly into the expansion of its functions, it has distributed test capabilities and the same can be applied to all test environment that based on the TTCN-3 standard and follow the TCI structure; Used by the ways in the low demand software environment, can adapt to more testing system applications; adopt a flexible modular structure, reducing the the coupling and increase the system's flexibility and scalability.
