In this lab you will be building a card game using Ruby Classes and Rspec Tests. Our game will include classes for: PlayingCard, CardDeck, HandOfCards, and CardPlayer. By the end of this lab you should be able to simulate a multi-player game of go_fish.

First, make sure you've installed the rspec gem.

From the command line (inside the cloned repo directory) run:

gem install rspec # individually install the rspec gem
# or
bundle install # install all the gems listed in the Gemfile

Next, check that the rspec tests are working (they should be failing!):

rspec
# or
rspec spec/1_playing_card_spec.rb
# or, run only test that match your search
rspec spec/2_card_deck_spec.rb -e "shuffle"

Take a look inside go_fish.rb and you'll see some boilerplate code for our classes.

Your classes will have the following interfaces:

This will allow us to run "Driver Code" along the lines of:

# GAME SETUP

deck = CardDeck.new
deck.shuffle

card = deck.draw_one
two_cards = deck.draw(2)

cards1 = deck.draw(5)
h1 = HandOfCards.new(cards1)
p1 = CardPlayer.new(hand: h1)

cards2 = deck.draw(5)
h2 = HandOfCards.new(cards2)
p2 = CardPlayer.new(hand: h2 )


# GAME PLAY

wanted_rank = "3"
puts "p1, do you have any... #{wanted_rank}'s?"
if p1.hand.any?(rank: wanted_rank)
    cards = p1.hand.take!(rank: wanted_rank)
    p2.hand.push(*cards)
else
    puts "Go Fish"
    p2.hand.push(deck.draw)
end

Your first goal will be to build your PlayingCard objects. Here's some raw data (no jokers!):

RANKS = ["A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"]
SUITS = ["C", "D", "H", "S"]
SORTED_CARDS = [
    "AC", "AD", "AH", "AS", "2C", "2D", "2H", "2S", "3C", "3D", "3H", "3S",
    "4C", "4D", "4H", "4S", "5C", "5D", "5H", "5S", "6C", "6D", "6H", "6S",
    "7C", "7D", "7H", "7S", "8C", "8D", "8H", "8S", "9C", "9D", "9H", "9S",
    "10C", "10D", "10H", "10S", "JC", "JD", "JH", "JS", "QC", "QD", "QH", "QS",
    "KC", "KD", "KH", "KS"
]

Follow the tests to get started!

You can run your game from the command line by typing:

ruby go_fish.rb

Hint: Take a look at the "Drive Code" at the bottom of go_fish.rb!

You can also load your code into Pry to test your assumptions:

pry
> load 'go_fish.rb'
> card = Card.new({...})
> card.face # "AC"
