Yes. I Test and Challenge players all the time. It is a basic pillar of my game style. I think game abilities and such should ENHANCE the player using their character to overcome a test challenge. Not Replace it. I'm not a fan at all of the way a DM just says "oh your character encounters something something" and the player just rolls a dice and says "oh my character does something something".
My typical default test/challenge is roughly at the Scooby Do, Hardy Boys, Nancy Drew such level...often taken right from the cartoon or book. But for some players then get much harder ones.
