There are easy and small finite tests, larger tests, static and moving tests, and then while I am a lowly mudansha in Aikido I can fly and move quite well. So offering a shomen or a wrist grab, or just standing there and seeing if he can "suggest" I fall, can be a pleasant way to spend an afternoon for both parties. In fact I'd be willing to bet no one even breaks a sweat.
