Embodiment
System can be regarded as by a plurality of focus and makes up realization, for example, and service logic, performance, data storage, test etc.At present extensively can not good treatment to cross a plurality of often be the behavior of incoherent module to OOP (Object oriented programming mode) programming mode that adopts.A kind of new Aspect Oriented Programming mode (AOP) has appearred in recent years, as Aspea is the implementation tool of the Aspect-oriented programming of c++, AOP is the piece-rate system focus clearly, the focus of each crosscut is independently realized with module, these modules are recombinated (also cry and inweave or combination) together by the rule of appointment again, thereby be built into final system.In AOP, these modular units are aspect (aspect).
The principle that the present invention separates according to the AOP focus, characteristics in conjunction with embedded system test, traffic issues and test problem are summed up as two different aspects to be solved respectively, when testing, needs aspect two, interweave, thereby can realize repeated test, can avoid in production system, bringing into unnecessary test code again.
