Optimization Test Sequence of CTCS-3 On-Board Equipment

How to generate the optimization test sequence by combining test cases is the key problem of testing on-board equipment.In this paper,the problem of test sequence generation is transformed into Chinese postman problem,and then the genetic algorithm is used to resolve the problem of Chinese postman.Firstly,the on-board modes transfer diagram is transformed into sub-sequence diagram,and then test sequence is obtained with the genetic algorithm.The experiment results show that the test efficiency is well improved with the proposed method and it is feasible to deal with the problem of test sequence generation.
