Iteration 1
Cards
A Card represents a single flashcard in our set. It stores a question, an answer, and a category.
Use the tests provided to drive the development of your Card class. From the root directory of your project, run the test like this:
rspec spec/card_spec.rb
If you haven’t already, you will need to install rspec:
gem install rspec
If your Card class is written properly and is located at ./lib/card.rb, you should be able to open a pry session from your flashcards directory and interact with it like so:
# double check that you are in your flashcards project directory!
pry(main)> require './lib/card'
#=> true
pry(main)> card = Card.new("What is the capital of Alaska?", "Juneau", :Geography)
#=> #<Card:0x00007f800e29f0c8 @question=""What is the capital of Alaska?", @answer="Juneau", @category=:Geography>
pry(main)> card.question
#=> "What is the capital of Alaska?"
pry(main)> card.answer
#=> "Juneau"
pry(main)> card.category
#=> :Geography
Turns
Create a Turn class and an accompanying test file with the following methods:
initialize(string, card)- A turn is initialized with two arguments. The first is a string representing a guess to a card’s question. The second argument is aCardobject representing the current flashcard being shown.guess- This method returns the guesscard- This method returns the Cardcorrect?- This method returns a boolean indicating if the guess matched the answer on the Card.feedback- This method either returns"Correct!"or"Incorrect."based on whether the guess was correct or not.
The Turn class should respond to the following interaction pattern:
pry(main)> require './lib/turn'
#=> true
pry(main)> require './lib/card'
#=> true
pry(main)> card = Card.new("What is the capital of Alaska?", "Juneau", :Geography)
#=> #<Card:0x00007f800e29f0c8 @question=""What is the capital of Alaska?", @answer="Juneau", @category=:Geography>
pry(main)> turn = Turn.new("Juneau", card)
#=> #<Turn:0x00007f99842f0998 @card=#<Card:0x00007f800e29f0c9 @question=""What is the capital of Alaska?", @answer="Juneau", @category=:geography>, @guess="Juneau">
pry(main)> turn.card
#=> #<Card:0x00007f800e29f0c8 @question=""What is the capital of Alaska?", @answer="Juneau", @category=:Geography>
pry(main)> turn.guess
#=> "Juneau"
pry(main)> turn.correct?
#=> true
pry(main)> turn.feedback
#=> "Correct!"
We also want to make sure that incorrect guesses are handled properly.
pry(main)> require './lib/turn'
#=> true
pry(main)> require './lib/card'
#=> true
pry(main)> card = Card.new("Which planet is closest to the sun?", "Mercury", :STEM)
#=> #<Card:0x007ffdf1820a90 @answer="Mercury", @question="Which planet is closest to the sun?", @category=:STEM>
pry(main)> turn = Turn.new("Saturn", card)
#=> #<Turn:0x00007f998413ee60 @card=#<Card:0x007ffdf1820a90 @answer="Mercury", @question="Which planet is closest to the sun?", @category=:STEM>, @guess="Saturn">
pry(main)> turn.card
=> #<Card:0x007ffdf1820a90 @answer="Mercury", @question="Which planet is closest to the sun?", @category=:STEM>
pry(main)> turn.guess
=> "Saturn"
pry(main)> turn.correct?
=> false
pry(main)> turn.feedback
=> "Incorrect."
Remember, #<Turn:0x00007f998413ee60 ... > means “A Turn Object” or “An Instance of the Turn Class”.
