Hardware-in-the-loop test system and method and storage medium

The invention relates to the technical field of automobile testing, in particular to a hardware-in-the-loop testing system and method and a storage medium, and the system comprises a tested object, a real-time machine and an upper computer; the test module is used for testing a communication bus and/or an analog-digital signal of a tested object in real time; the upper computer is used for issuing a first test control instruction to the real time, the upper computer is provided with a packaging module obtained by packaging an Ethernet protocol stack, a second test control instruction is issued to the tested object through the packaging module, and a test result of the tested object is obtained through the packaging module, so that the hardware-in-the-loop test of the tested object is realized. Therefore, the problems that graphical conversion needs to be carried out on an Ethernet protocol stack deployed in real time in the related technology, the workload is large, whether functions before and after conversi
