Personally I like having real life friends over and having them test it. It's always a good time! Always know you can do better and improve. The more games you make, the better you may become, the more fun people will have playing it! Just keep a positive attitude and keep trying.

Oh man, if I could get some of my friends to play any of my games, it would be a HUGE boost. I have a buddy that's tested out most of my stuff... once. His feedback is always vague and trying to get him to test out changes is like herding cats. Beta testing is a job, and I don't have friends willing to work for me for free. Even if he likes the game, there's so much vying for his attention, he'll never get around to doing it again. Once he's curiosity is satisfied, that's it, game over. No matter what I do, he's done.
Interestingly enough, I had an easier time developing and testing board games, as board games give you a captive crowd that aren't so easily distracted. My successful game Line Dice (on Amazon now) was thoroughly tested through over a dozen testing sessions with my gaming group. It's hard to do that kind of testing with video games.
