The invention discloses a redundant array of independent disks (
RAID) card, a test method, device and
system thereof and a host, and relates to the technical field of storage, the method is applied to an
RAID card, and the method comprises the following steps: acquiring an integrated test command of a target
firmware system sent by a test host; determining a target
test case in a target subsystem in the test framework according to the integrated test command; executing the target
test case by using the test framework to obtain an integration test result of the integration test command, and sending the integration test result to the test host; according to the invention, through the arrangement of the test framework in the
RAID card, redundant codes during writing of the
test case can be reduced, and the
workload and resource waste of testers are reduced; according to the method, the
test frame uniformly performs distribution execution of the test cases and judgment and statistics of the test results, so that the number of times of interaction with the test host can be reduced, the
test efficiency is improved, and an automatic integrated test for docking the RAID card with the test host is conveniently realized.
