Embodiments of the present disclosure provide an apparatus for testing a storage network comprising a processor configured to generate a configuration signal in response to a test request; and a tester coupled to the processor and configured to, by the configuration signal, operate under different operation modes so as to test different to-be-tested objects in the storage network. The test request indicates an operation mode of the tester, wherein various types of to-be-tested objects in a storage network can be tested by one test device, at a low test cost and with more convenient operations.
