Iteration 2
Storing Cards in a Deck
Create a Deck class with an accompanying test file. A Deck is initialized with an array of Card objects. The Deck class should respond to the following interaction pattern:
pry(main)> require './lib/card'
#=> true
pry(main)> require './lib/deck'
#=> true
pry(main)> card_1 = Card.new("3","Hearts")
#=> #<Card:0x00007fa16104e160 @suit="Hearts", @value="3">
pry(main)> card_2 = Card.new("4", "Clubs")
#=> #<Card:0x00007fa160a62e90 @suit="Clubs", @value="4">
pry(main)> card_3 = Card.new("5", "Diamonds")
#=> #<Card:0x00007fa161a136f0 @suit="Diamonds", @value="5">
pry(main)> cards = [card_1, card_2, card_3]
pry(main)> deck = Deck.new(cards)
#=> #<Deck:0x00007fa160a38ed8...>
pry(main)> deck.cards
#=> [#<Card:0x00007fa16104e160...>, #<Card:0x00007fa160a62e90...>, #<Card:0x00007fa161a136f0...>]
pry(main)> deck.count
#=> 3
The Round
A Round will be the object that processes responses and records guesses. A Round is initialized with a Deck. The idea is that when we start a Round, the current card is the first in the deck (the first in the Deck’s array of Cards). When we make a guess, the guess is recorded, and the current card becomes the next card in the deck.
The record_guess method is the crux of this problem. The record_guess method takes a hash representing the guess. It should create a new Guess object with the appropriate response and Card. It should store this new guess, as well as return it from the record_guess method. Also, when the record_guess method is called, the Round should move on to the next card in the deck.
A Round should respond to the following interaction pattern:
pry(main)> require './lib/card'
#=> true
pry(main)> require './lib/deck'
#=> true
pry(main)> require './lib/round'
#=> true
pry(main)> card_1 = Card.new("3","Hearts")
#=> #<Card:0x00007f972a227f18 @suit="Hearts", @value="3">
pry(main)> card_2 = Card.new("4", "Clubs")
#=> #<Card:0x00007f9729a87998 @suit="Clubs", @value="4">
pry(main)> deck = Deck.new([card_1, card_2])
#=> #<Deck:0x00007f972a214288...>
pry(main)> round = Round.new(deck)
#=> #<Round:0x00007f972a1c7960...>,
pry(main)> round.deck
#=> #<Deck:0x00007f972a214288...>
pry(main)> round.guesses
#=> []
pry(main)> round.current_card
#=> #<Card:0x00007f972a227f18 @suit="Hearts", @value="3">
pry(main)> new_guess = round.record_guess({value: "3", suit: "Hearts"})
#=> #<Guess:0x00007f972a15c160 @card=#<Card:0x00007f972a227f18 @suit="Hearts", @value="3">, @response="3 of Hearts">
pry(main)> new_guess.class
#=> Guess
pry(main)> new_guess.correct?

pry(main)> round.guesses
