Fuzzy testing method and device of real-time operating system and computer equipment

The invention relates to a fuzz testing method and device for a real-time operating system, computer equipment, a storage medium and a computer program product. The method comprises the steps of creating a simulator according to a to-be-tested real-time operating system, determining a test key point, running the to-be-tested real-time operating system through the simulator, obtaining a memory state in the running process of the to-be-tested real-time operating system, executing a target test task based on the test key point, and obtaining an execution result. And generating a test result of the real-time operating system to be tested according to the memory state and the execution result. According to the embodiment, the fuzz test of full-system simulation is carried out on the real-time operating system to be tested on the basis of the virtual hardware, namely the simulator, so that compared with the traditional technology that the real-time operating system is tested in real hardware, the test difficulty ca
