Distributed system sub-module interaction test method and device

The embodiment of the invention provides a distributed system submodule interaction test method and device, and the method comprises the steps: obtaining submodule interaction information, and carrying out the caching of the submodule interaction information; obtaining preset test mode information, and testing the sub-module interaction information according to the preset test mode information toobtain final test information, wherein the sub-module test information comprises one or more of upstream sub-module interaction request information, downstream sub-module interaction response information and sub-module interaction feedback information. Interactive information of a distributed system sub-module is cached, so that the interactive information is convenient to read in a subsequent test process; the interaction request information of the upstream sub-module and the interaction response information of the downstream sub-module are recorded and analyzed, so that the data transmissioncondition between the sub
