a trial to determine something's validity
To test is to try out a supposition to determine if it is correct. "Run it up the flagpole and see if people salute it" is the concept here. Any explanation that makes sense has the potential to be correct or incorrect once it is actually tried in "the real world." The Test characteristic will always want to try things out before using it. This can weed out faulty items before they break down when one relies on them. However, it can also waste time when it is of the essence or waste one of the three wishes just to see if it works.
syn. trial of validity, examination, audit, inspection, scrutinization
