Design of Intelligent Testing System for Aerospace Software

Résumé fourni par la source

With the increasing number of space missions, the traditional test methods used in space control software have been difficult to meet the requirements of model development. By analyzing the traditional test process and automated test traps of aerospace control software, an intelligent test strategy was selected and an intelligent test system was designed. The system uses an object-oriented approach to abstract encapsulation of telecontrol and telemetry protocols, enabling test engineers to describe test behavior in a very concise way based on these abstract encapsulations in test scripts. The system also provides a range of smart test keywords, while also providing an intelligent sequencer. With the help of an intelligent sequencer, the system can run in line with the timing of the physical or virtual target, and translate the keywords in the test script into test behaviors, so that the test cases can be automated execution. At present, the system has been successfully applied to the testing of hundreds of aerospace control software, and more than 95% of the test cases of these software are tested based on this system, which has obvious effects on reducing software testing costs and improving testing efficiency.
