一种TTCN-3编解码器的演化方法

摘要

Software requirements' frequent change always leads to the evolution of software.When using TTCN-3 to test the software which has been evolved,we usually need to redevelop the codec for most test suite.Therefore,it is necessary to automate the evolution of the original codec in order to improve the test efficiency.In this paper,we analyzed the state-of-the-art of TTCN-3 codec,and proposed a new method of evolving codec by combining the test suite.Experiments demonstrate that this method is feasible,and it is convenient for the TTCN-3 test system.%软件需求常常发生变化,导致软件经常被演化.由于使用TTCN-3对演化后的软件进行测试时需要为大部分测试脚本重新开发编解码器,因此有必要对原来的编解码器进行演化,以提高测试效率.分析了TTCN-3编解码器的研究现状,提出了一种结合测试套文件对编解码器进行演化的方法.实验表明,该方法是可行的,为TTCN-3测试系统的使用提供了方便.
