The invention discloses a software inspection method, device and system. The method is based on a cloud platform in which a plurality of master server and a plurality of slave servers are arranged; a user can upload an inspection task via a client, wherein the task comprises an inspection script suite composed of at least one script use case; the master server obtains at least one script use case by analyzing after receiving the inspection task, and distributes each script use case to the slave servers with reference to a preset distribution policy; the slave servers execute the script use cases and feed back execution results to the master server; furthermore, the master server collects all the execution results and sends the collected execution results to the client. According to the software inspection method, automatic inspection can be realized by virtue of the cloud platform; the master server distributes the script use cases to the corresponding slave servers, and all the slave servers are capable of processing concurrently, and therefore, the inspection efficiency is improved. In addition, the user only needs to upload the script use cases needed by inspection and the cloud platform will traverse and execute all the script use cases, and therefore, the problems of missing inspection and wrong inspection can be avoided.
