For one thing, it's a great bonding experience for you and your dog, and it's fun. You meet people, go places, etc.
Although some of it has been watered down, it is still a good test. The journey will tell you what you need to know about the dog, and the result will tell everyone else.
You might get more answers if your grammar, sentence structure and spelling weren't so poor, and the question wasn't so insulting........
