Research on Function Test of OSEK/VDX Operating System
In order to overcome the shortages such as the incomplete test routes and high redundancy in traditional operating system test by using the classification tree method,this paper comes up with a flow chart method which takes the system service interface as target and is divided by the type of conformance class.It also assesses the importance of each interface.This test method can fully list all kinds of combinations of each interface in the called process.So it not only raises the rate of test coverage,but also reduces coding work via code reuse,which improves test efficiency.The outcome shows that the workload by using this method is only two-thirds of that in the traditional method.
