The situation that calls for testing feels like being confused or curious.
The thought that generates a test looks like this: “If X is true, it is (more/less) likely that Y is true. I can examine Y by doing ___.”
For example, one day my computer was running slowly. There were a bunch of possible explanations, but my room was hot, dusty, and it’d been a long time since I cleaned it out, so I suspected the slowness was because of overheating. “If my computer is slow because of overheating, it is less likely that it will be slow if I remove the case to increase ventilation. I can examine that by removing the case.” I pull the case off, and the computer runs normally again.
Most of the examples tend to be banal, though, and so I’ve forgotten them. (Not quite sure how I remembered that one.)
Ideally you should also point a room fan at the inside of the computer after you take off a panel. Some systems, especially small form factor PCs and rack mount servers, actually need the case in order to be properly cooled. Removing a panel means that e.g. an exhaust fan no longer forces air across passively cooled components near the intake.
Right, thanks. I probably need to work on noticing when I’m confused. Your example reminded me of a few cases where I’ve behaved similarly (everyone I expect has), so I guess I do some “testing” occasionally.
