Regression testing method of UAV flight and management software

In order to solve the large embedded software testing problems, an automated regression testing method based on system snapshot was proposed. Taking unmanned aerial vehicle(UAV) flight control software as a case study, some key technology researching, system architecture designing and experiment analyzing were carried out by degrees. The system snapshot technology was used to decouple the test cases which had complex relationship with each others, then transformed complex systems testing into some flexible unit testing. With CPPUnit testing framework, an automated regression testing system structure was established, and the function and implementation process of each part were deeply analyzed. Furthermore, based on the system snapshot technology, the process of automated regression testing and the preparation of test cases were designed. Two kinds of experimental result of a large UAV flight control software testing using different method was given. Through comparative analysis of the evidence-based data, test system's effectiveness was verified.
