One test case generation method for SW&HW reliability co-testing

Today, more and more software-intensive equipments are used in weapons, and their reliability is gradually being looked closely. For these equipments, software and hardware are coupling; their reliability can´t be verified separately. Design testing profile is an important work to reliability verification. Hardware test profile design method is mature relatively. Software test profile design and test case generation method is developing. Although several operation profile construction methods have been proposed, they are not fit for hardware & software (SW&HW) co-testing. This paper combines testing profile of hardware, with utilized information of mission profile and environment profile, divides operation profile into three layers and model by diverse UML diagrams. This method considers both input parameters complexity and real-time requirements. It can be used in operation profile design and test case generation of SW&HW reliability co-testing.
