This invention belongs to the field of software-defined radar communication middleware and software testing, and relates to evaluation technology for software-defined radar communication middleware. Specifically, it provides an open evaluation system and method for software-defined radar communication middleware to solve the problems of inflexible test scenario construction and low test code reusability. This invention provides a task-driven software testing evaluation method that can construct test scenarios according to task requirements, complete the test process, and automatically process test result data, improving testing efficiency. Simultaneously, this invention constructs an evaluation system combining a control and management terminal with node servers and a database. Through modular design of the evaluation system, flexible construction of test scenarios is achieved. Vertical and horizontal partitioning of the database solves the problem of significantly reduced query and insertion efficiency caused by the gradual increase in data volume, thereby improving the availability and scalability of the evaluation system.
