Challenge

Implement a program that keeps track of tennis game scoring.

Tennis Scoring Summary

A tennis game is won by the first player to score four points in total and at least two points more than the opponent. The words used to describe scores in tennis are unusual:

Point value	Word
0	Love
1	Fifteen
2	Thirty
3	Forty

A set is won by winning at least six games and at least two games more than the opponent. Special case: if the set score is 6-5 and the trailing player wins--making the set score 6-6--the next game wins the set.

Summary

Implement a console program according to the specifications below. You should have one commit for iteration one and a separate commit for iteration two. Your program will be evaluated by a set of automated tests upon submission. Don't worry, failing tests will not imply immediate disqualification. Also, don't worry if you only satisfy the requirements of iteration one. Not all candidates have time to accomplish both tasks, but it looks better if you do. If you do finish both iterations, we will diff commits one and two to see how you approached the exercise iteratively.

Technical Details

The program should accept the optional arguments described in Usage Description and set initial state accordingly
The program should validate the passed arguments and print the Usage Description if an invalid argument is passed
- Note: setting both --p1score and --p2score to "Advantage" for initial state is invalid since only one player may hold the advantage at a time
Your program should block for additional user input until the game or set has been won (depending on mode) and then exit
Valid input strings include:
- "<Player 1> scores!" - where <Player 1> could be any name
- "<Player 2> scores!" - where <Player 2> could be any name
Your program should validate input strings and return a message of "Invalid Input" if the user inputs an invalid string

Usage Description

--p1name        Player 1's name
--p2name        Player 2's name
--p1score       The initial score for player 1 - (one of Love, Fifteen, Thirty, Forty, Advantage - default is Love)
--p2score       The initial score for player 2 - (one of Love, Fifteen, Thirty, Forty, Advantage - default is Love)
--p1wins        The initial # of wins for player 1 - (an integer between 0 and 6 - default is 0)
--p2wins        The initial # of wins for player 2 (an integer between 0 and 6 - default is 0)
--mode          Whether to run the program in game mode or set mode (one of game or set - default is set)

Iteration One

Feature: Game scoring

Scenario Outline: Player scores

Given The current score is <player1score> to <player2score> When The system receives <scoreEvent> Then The system outputs <result>:

Examples:

player1score	player2score	scoreEvent	result
Fifteen	Thirty	Player 1 scores!	Thirty-Thirty
Forty	Thirty	Player 1 scores!	Player 1 wins the game
Love	Love	Player 2 scores!	Love-Fiftee
Forty	Thirty	Player 2 scores!	Deuce!
Forty	Forty	Player 1 scores!	Advantage Player 1!
Advantage	--	Player 1 scores!	Player 1 wins the game
Advantage	--	PLayer 2 scores!	Deuce!
