基于状态机的并行测试实现

Realization of Parallel Test Based on State Machine

并行测试技术是自动测试系统发展的热点。利用状态机原理,将耗时长的测试操作分解为多个小片,每个小片只占用一小段时间,由定时器依据条件依次调用,在定时器未响应的间隙,Windows程序赖以生存的消息循环得以继续,用户界面保持"友好"的状态。并且利用并行状态机可以实现线程内部测试过程的并行运行。实际应用表明,通过此方法可以很好的提高测试效率,降低测试软件维护难度。

Parallel test technology is a hot point of development of automatic test system. Based on state machine theories, long time test operation divides into a series of action that takes less time. And these actions are called in turn by timer and message cycle of windows can go on using timer＇s idle time to keep program interface friendly. The idea of parallel state machine is put forward and with parallel state machine parallel test can be realized in one thread. Practical application shows that the method can improve test efficiency and reduce difficulty of software maintenance.
