Description

Technical Field

[0001] This invention relates to the field of aero-engine control software, and in particular to a method and system for acquiring and storing source code structure coverage for integrated environments. Background Technology

[0002] As a core component of an aircraft, the safety of the aircraft engine directly impacts flight safety. In the airworthiness standard DO-178C, section 6.4.4, structural coverage analysis involves two steps: requirements-based coverage analysis and structural coverage analysis. The first step analyzes test cases related to software requirements to determine if the selected test cases meet specific criteria. The second step determines that the requirements-based test procedures check the code structure against applicable coverage criteria. As highly safety-critical software, aircraft engine control software requires coverage analysis to check its code structure. If the applicable coverage is not met, additional activities should be implemented to address the issue.

[0003] Structural coverage analysis identifies which code structures (including interfaces between components) are not checked by requirements-based test procedures. Requirements-based test cases may not be able to fully check the code structure (including interfaces), therefore, structural coverage analysis is often performed on the source code and additional verification is generated to ensure the adequacy and accuracy of the tests.

[0004] Unlike unit testing, integrated hardware and software environments are characterized by high complexity and high cost. Structure coverage collection requires coordinated hardware and software testing and may involve real physical hardware or complex simulation environments. Furthermore, structure coverage collection in integrated hardware and software environments encounters problems such as spatial and temporal dilation and how to communicate and store coverage information. Relying entirely on manual analysis of source code structure coverage is not only time-consuming and labor-intensive but also prone to errors. Therefore, it is necessary to design a method that not only supports the collection of source code structure coverage but also automates batch processing to complete the collection and storage of structure coverage. Summary of the Invention
