Generating technique for software reliability test data based on test profile

In order to generate software reliability test data for automatic flying control system software, some new concepts of software reliability including test profile, environmental profile are established. The generating technique of test profile from mission profile and the generating method of test data obtained from test profile are developed, i.e. the input data is classified as the system mode data and environmental data, then system mode profiles and environmental profiles are formed under the mission profile respectively. Furthermore, the two formed profiles are combined as a test profile. The environmental data are decomposed into controlled components and stochastic components, and the simulation method is reused to generate the controlled components to produce the environmental data for the complicated association test. It is shown that the proposed method can describe the practical cases of software application more accurately with a similar way to describe the reliability test of hardware, and can be regarded as a reliability test foundation for synthesizing hardware and software systems.
