The present application discloses a
fault injection test
system, method, device, medium and product, which relate to the field of fault testing technology, including a
server, an external expansion device, a host computer and a test unit. The host computer selects the
signal to be tested and the fault type, and sets the test unit between the
server and the external expansion device. Under the control of the host computer, the test unit adjusts the
internal link through the first test module and the second test module to achieve
fault injection between the
server and the external expansion device. The present application can achieve
fault injection testing between the server and the external expansion device by setting the host computer and the test unit. Therefore, it is beneficial to avoid artificial
welding signals to achieve
signal fault injection, and can solve the technical problems of high test cost, low efficiency and relatively limited testing caused by manual operations such as
welding for fault injection testing. It is beneficial to reduce test costs, improve
test efficiency, and improve the comprehensiveness of fault injection testing.
