Parallel Testing Design And Implementation Of Teaching Example Based On TTCN-3

TTCN-3 is a test of ETSI launch description language, is used in the black box testing. The biggest advantage of parallel testing is to improve test efficiency. The most representative feature of TTCN-3 language is parallel testing.TTCN-3 is a powerful language, but in the early development, preparation is very demanding. Beginners need to understand the TTCN-3 core language, learning process is difficult; Tests need to be performed on a specific platform, development cycle is long in the actual application, become the bottleneck of the current application. So this thesis designed a complete parallel test example based on the TTCN-3 to help beginners master the development language quickly, and aided design a parallel test demo system, to guide the developers to understand the development process, thus to promote the application of TTCN-3 test technology.This thesis mainly research by TTCN-3 implementation of parallel testing, first introduced the selection principles and design principle of the system under test, implements a moderate scale, logical, concise parallel system under test; Then on the basis of the system under test, clear testing purposes, analyzes the commonness and characteristics of each test purpose, writing the abstract test set based on testing purposes. After introducing the design of the peripheral test module, including the function of the adapter and decoding, then concluded the test results; implementing a demo system based on TTCN-3 parallel testing. Thesis finally, summarizes the full text and proposed the next research direction.
