Tennis Kata

This Kata is about implementing a simple tennis game. I came up with it while thinking about Wii tennis, where they have simplified tennis, so each set is one game.

The scoring system is rather simple:

• Each player can have either of these points in one game 0 15 30 40
• If you have 40 and you win the ball you win the game, however there are special rules.
• If both have 40 the players are deuce.
  • If the game is in deuce, the winner of a ball will have advantage and game ball.
  • If the player with advantage wins the ball they win the game.
  • If the player without advantage wins they are back at deuce.

Running the tests
