A simple test for aphantasia that I gave my kids when they asked about it is to picture an apple with three blue dots on it. Once you have it, describe where the dots are on the apple.
Without aphantasia, it should be easy to "see" where the dots are since your mind has placed them on the apple somewhere already. Maybe they're in a line, or arranged in a triangle, across the middle or at the top.
