The acid test for gold is to rub the gold -colored item on black stone, which will leave an easily visible mark. The mark is tested by applying nitric acid, which dissolves the mark of any item that is not gold. If the mark remains, it is tested by applying aqua regia (nitric acid and hydrochloric acid).

Figuratively, acid test is any definitive test for some attribute, e.g. of a person’s character, or of the performance of product. Wikipedia
