Methodology

  1. First break down the user stories and identify nouns and verbs to determine the classes and methods that would be required.

  2. Created a files for each class: Takeaway and Menu.

  3. Created spec files for each class: 'takeaway_spec.rb' and 'menu_spec.rb'.

  4. Started writing tests to check functionality.

  5. Used 'rubocop' to ensure best practice formatting.

  6. Add methods to the corresponding classes to pass the tests.

How to use

Bellow is a pry transcript of how the program runs from a users perspective:

[1] pry(main)> require './lib/order'
=> true
[2] pry(main)> dominos = Takeaway.new
=> #<Takeaway:0x007ffb1a87f858
 @order=
  #<Order:0x007ffb1a87f808
   @customer_order={},
   @menu=
    {:Milano=>19.99,
     :Ardente=>19.99,
     :Sicilia=>19.99,
     :Verona=>19.99,
     :Roma=>19.99}>>
[3] pry(main)> dominos.order.add_item(:Roma, 5)
=> 5
[4] pry(main)> dominos.order.add_item(:Margherita, 2)
RuntimeError: Item is not on the menu.
