Scenario-based software operational profile

As the diversity of software status and the uncertainty of software operation, the traditional methods to construct software reliability operational profile are difficult to be applied to reliability testing. This paper introduces an approach to generate operational profile based on scenario. It partitions the usage of software into various paths of software running according to the users and missions. With the proposal of scenario, a relation between user´s activities and software´s execution is established. Through the correlation which allows software inputs to be obtained from system usage, the generation of reliability test data could be implemented. The effect of this approach is illustrated with an example of missile control demonstration software (MCDS).
