Conduct functional testing to ensure all essential features work correctly.
Conducting functional testing to ensure all essential features work correctly involves systematically verifying that the customized OS behaves as expected and fulfills its intended functionalities. This process typically includes creating test cases that cover various use cases and scenarios, executing these tests on the target hardware or virtual environment, and analyzing the results to identify any discrepancies or failures. Functional testing helps validate that core features such as networking, system utilities, and application functionality operate as intended, ensuring the overall reliability and usability of the OS.
