How do I do a thorough hardware check-up for water-exposed MacBook Pro?

How do I discover potential hardware issues in a liquid-exposed MacBook Pro, other than trying to use all hardware features manually? Is there some general diagnostic test that can be run to look for hardware problems? --- I spilled a full glass of regular tap water over a late 2016 MacBook Pro 13" a few days ago. I've let it dry upside down (hanging over the edge of a table) for nearly four days, and I'm happy to see it boots fine. Two issues appeared at first: Bluetooth was "not available", and the whole system stuttered and slowed down for a few seconds when changing the screen brightness. Both of these issues disappeared on a second reboot, and bluetooth as well as screen brightness behaves normally. From just using the computer, the keyboard, trackpad, hard drive, battery, screen, wifi, speakers, microphone, and camera all seem to work fine. But I would prefer a more systematic approach to discover any lurking problems.
