The NVIDIA Tegra chip is used in the automotive industry, with an emerging usage in autonomous vehicles. Tegra display testing faces challenges that include a lack of negative testing in the test infrastructure and failure to meet some safety requirements to comply with international and industry standards. We implemented more testing on the input/output control function calls to verify the display system behaves as expected with both valid and invalid inputs and fixed any system bugs that were revealed by the implemented test cases. We also refactored the codebase to satisfy different requirements for standard and safety builds. In total, we implemented 18 test cases, fixed 4 system bugs, integrated test cases to Tegra software’s continuous integration and continuous development pipeline, and refactored 3 functionalities on safety system build. With the work the team has accomplished, the display system is more robust, the codebase is also cleaner and more concise.
