FAQs

The main focus is to ensure that software integration testing practices in aerospace and defense applications comply with DO-178C guidelines, verifying that integrated software components function correctly as a complete system and meet all specified requirements.

Thorough integration testing helps identify potential system-level issues, verifies correct interaction between software components, and ensures that the integrated system behaves as expected under various conditions, all of which are crucial for the safety and reliability of avionics systems.

The checklist covers areas such as integration test planning, test case development, test environment setup, interface testing, system behavior verification, regression testing, and test results documentation and analysis.

The audit should involve software test engineers, systems integration specialists, quality assurance personnel, avionics software developers, and safety engineers to ensure a comprehensive evaluation of the integration testing process.

Integration testing audits should be performed after unit testing is complete and individual software components are ready for integration. It should be conducted before system-level testing and continue throughout the integration process, with follow-up audits as needed for any major changes or updates to the integrated system.
