Abstract: This application relates to a method and system for micro-service testing, and a storage medium. The method for micro-service testing includes: performing simulation on a target micro-service based on machine learning; constructing a corresponding virtual micro-service based on a result of the simulation; initiating an invocation request for the target micro-service; redirecting the invocation request to the virtual micro-service; and returning a test result by the virtual micro-service in response to the invocation request. According to the method for micro-service testing, a virtual micro-service can be constructed by means of machine learning, to participate in testing and development in place of a real micro-service.
