Test method and system based on flow interception and asynchronous forwarding

The invention provides a test method and system based on traffic interception and asynchronous forwarding, a departure routing system in a production environment sends user traffic to departure system middleware under the condition of receiving the user traffic, so that the departure system middleware asynchronously forwards the user traffic to the departure routing system in a test environment. Therefore, the departure routing system in the test environment sends the user traffic to the corresponding service module. Under the condition of not influencing normal services, real user traffic in a production environment is intercepted and asynchronously forwarded to a test environment, so that the test environment has sufficient test data to cover various scenes, new functions are rapidly tested and verified, the process of repeated development and deployment is avoided, and the efficiency and quality of software development are improved. And the data used in the test environment is real user traffic, so that re
