Test Driven Development kata with Bowling Game

The idea of this repository is to contain a minimal setup for executing the Uncle Bob famous Bowling kata in C# using xunit framework.

The Bowling Score

The game consists of 10 frames as shown above. In each frame the player has two opportunities to knock down 10 pins. The score for the frame is the total number of pins knocked down, plus bonuses for strikes and spares.

A spare is when the player knocks down all 10 pins in two tries. The bonus for that frame is the number of pins knocked down by the next roll. So in frame 3 above, the score is 10 (the total number knocked down) plus a bonus of 5 (the number of pins knocked down on the next roll.)

A strike is when the player knocks down all 10 pins on his first try. The bonus for that frame is the value of the next two balls rolled.

In the tenth frame a player who rolls a spare or strike is allowed to roll the extra balls to complete the frame. However no more than three balls can be rolled in tenth frame.

Three laws of TDD

When doing the exercise, it is important to stick to the three rules of TDD. For more information click here.

1. You may not write production code until you have written a failing unit test.

2. You may not write more of a unit test than is sufficient to fail, and not compiling is failing.

3. You may not write more production code than is sufficient to pass the currently failing test.

Have fun!
