TDD Bowling Game

An example of doing Test-Driven Development using Bowling as the domain.

The game to be played

Below are some scenarios we can use to drive the development of the game.

• when rolling all gutter balls, the score is 0.
• when rolling all 2s, the score is 40.
• when the first 2 rolls are 2 and the rest are 3, the score is 58.
• when rolling alternating 2s and 5s, the score 70.
• when the first frame is a spare and the remaining rolls are all 2, the score is 48.
• when the first 2 frames are spare (as 2,8) and the rest score 2, the score is 56.
• when 10 frames have been bowled, don't allow any more to be bowled.
• when the first frame is a strike and the rest score 2, the score is 50.
• when the first 2 frames are strikes and the rest score 2, the score is 68.
• when rolling a perfect game, the score is 300.
• when rolling alternate strikes and spares, the score is 200.
