I'm going to test my boyfriend.
What do you want to find out by testing him?
I want to see what he's made of.
It would be better if you just trust your boyfriend instead of trying to test him. Testing him will probably make him doubt your trust in him, and possibly cause troubles in your relationship.
What if I love teasing him though? I want to see him squirm. I'm going to get him back if he ever tests me.
You could be causing strife in your relationship by testing your boyfriend. A relationship should be based on mutual trust, testing him like this undermines that.
