A method of test cases generation for real-time systems

Abstract

Real time software must satisfy not only functional correctness requirements but also timeliness requirements. A lot of real time research has focused on analysis rather than testing. During the execution of real time software, a sequence of events due to time take place between the concurrent processes. Because of the unpredictable progress of concurrent processes, multiple executions of real time software with the same test cases may produce different results. This nondeterministic execution behavior always creates problems in software testing. The paper is concerned with test case generation for real time systems. It includes: (1) a guideline on how to handle the nondeterministic properties of real time systems; and (2) the way test cases are generated using a dual language based model and path like testing strategy.
