One could say that everything about dating is a test: do we have similar goals? What kinds of mistakes does each of us make? How do we respond to those mistakes? Does it irritate me when he/she does something silly, or does it make me smile? Is my world better with this person it? Am I happier? How would I feel if he/she didn't want to see me again?
And so on.
I don't think most people consciously set up tests, but the process is supposed to be about asking questions and gathering information, so that you make a wise choice on whether or not the relationship should be permanent.
It is all different when you know for sure, from day 1, it isn't someone you would marry. Then you just have fun while it lasts.
