- We use this kata as a basis for discussion.
- Only care about the C# version of the kata. We haven't prepared the TypeScript or JavaScript versions.
- We'll talk about why you made the changes you did, how you did them, and just generally talk about other development principles using this code-base as our common ground.
- We're only looking for refactorings here. The overall behaviour of the code should not change. However, you are permitted to change the public interface if you deem it necessary.
- Fork this repo and make your changes there. We want to be able to see the resulting commits and code (ideally during your on-site interview).
- While we want you to be proud of what you do, please - Do not spend more than a few hours on this, and don't stress out. 😊
The aim of this Kata is to refactor the code into a state that you would be happy leaving for your peers (or your future self!) to work on.
As it stands, this scoring code was developed as a 'temporary' solution, that quickly became permanent. Now that the organization has realized this, you have been tasked with refactoring the code!
- We're looking for incremental improvements, so commit as often as you can.
- Use the tests to provide feedback on your changes.
- Ask yourself:
- Is the code readable?
- Does the code express intent well?
- Is there any obscure logic that could be simplified?
Tennis has a rather quirky scoring system, and to newcomers it can be a little difficult to keep track of. The tennis society has contracted you to build a scoreboard to display the current score during tennis games.
You can read more about Tennis scores here which is summarized below:
- A game is won by the first player to have won at least four points in total and at least two points more than the opponent.
- The running score of each game is described in a manner peculiar to tennis: scores from zero to three points are described as "Love", "Fifteen", "Thirty", and "Forty" respectively.
- If at least three points have been scored by each player, and the scores are equal, the score is "Deuce".
- If at least three points have been scored by each side and a player has one more point than his opponent, the score of the game is "Advantage" for the player in the lead.
