Beat the dealer 21

I have created a simple automated card game of can you beat the dealer at 21.

Two computer players play the game. Player and Dealer. Both the player and dealer will be given two cards from a shuffled deck. I have attempted to implement the solution using TDD.

Basic rules

• Numbered cards are their point values
• Jack, Queen and King count as 10
• Ace counts as 11
• Black Jack refers to 21 being reached with two cards only

User stories
