Targeting at hurdles on embedded software testing, concepts of user specification model and operational profile model are in-troduced and well described. Algorithms of automatically operational modeling are also designed and implemented, by applying which it helped improve system analyzing and advance testing process. Moreover, the applying of Markov chain provided key data which di-rected test case generating. Meanwhile, a operative tool based on these methodology is developed using REI (rose extensibility interface) and validated effective in real projects.
