Description

Technical Field

[0001] The present invention relates to the technical field of aero-engine control software, and particularly to an automated construction method for a FADEC software simulation test environment. Background Art

[0002] During the development of aero-engine control software (FADEC), the simulation test environment is an important means to verify the software functions and performance. By executing test cases in the simulation test environment and collecting the code structure coverage rate, the efficiency of FADEC software verification can be effectively improved. However, there are the following two major problems in the construction of the current simulation test environment: Manual intervention problem: The construction process of the test environment requires manual intervention, including the generation of full digital simulation, coverage instrumentation, and the control of the test environment baseline, etc. This manual operation method is inefficient and error-prone. Test environment difference problem: The simulation test environment usually includes a desktop test environment and a cloud node test environment. There are differences between these two test environments, resulting in the inability of automated test cases to be universal in the two test environments, thus affecting the overall efficiency of software verification.
