Writing "social network" in go lang, part 8, writing tests and messenger HD

I decided to try to write a "social network", like facebook, vkontakte and such, for fun, in go lang ( http://golang.org ). In the this part we continue to write test for our web socket protocol and for basic actions like registration and authorisation. Also we add slight modifications to our messenger interface and add new API call. All source code (including rebuilder.php which uses darwin-notify from my unrealsync project) is available at github: https://github.com/YuriyNasretdinov/social-net/tree/part8 Live demo is available at http://vbambuke.ru/
