On the one hand, when high-speed data transmission or platform single-machine equipment testing is performed, because different projects have unique load interfaces and platform interface requirements, special testing work needs to be customized for each project. The development period is long, software and hardware are required to be debugged in a combined mode each time, and a large amount of manpower and material resources are consumed. When the external joint debugging is carried out, a tester has to carry a test tool single board and high-speed ground inspection equipment to serve as standby in the process of docking with a client, and the equipment is inconvenient to carry, so that the complexity of test work is increased. On the other hand, when a tester executes a test task, a plurality of test tools, high-speed ground inspection equipment and satellite simulation software are often required to be used simultaneously, and the test flow is very complicated. Especially in the batch testing stage, the complex flow seriously affects the testing efficiency. In addition, in the conventional high and low speed load data test and platform data test, the generation mode of the test data is relatively single, and is generally limited to increment, decrement data or fixed values. This single data generation approach severely impacts test coverage and accuracy.
