s2, creating a flow in the middle working area, dragging a corresponding message frame from the message frame template to a blank area, and importing the message template into a database through excel;
s3, displaying a flow part of the configuration flow under the message template in the working area, and dragging a flow selection flow step;
s4, classifying the design template area according to a test system, displaying the existing instruction frame, state frame and numerical frame, selecting the existing template to generate a test flow, and setting the condition attribute, trigger time and parameter simulation setting parameters of the flow in the attribute editing area;
s5, performing simulation configuration, returning to an execution interface, selecting a required equivalent system, executing all starting operations, and completing the equivalent configuration.
