Another definition of “acid test” in USA slang is a test that will absolutely settle the issue at hand. For example, if you’ve just built a bridge and you want to know whether it will support a dump truck, the acid test would be to load up a dump truck and drive it over the bridge. Whatever the outcome, you would then **know** beyond a doubt whether the bridge can support a dump truck.
However, in the context of your question, I think that Little Miss’s answer is what you’re looking for.
