Description

This program simulates ordering food from a takeaway. Orders are made from a menu, and orders are confirmed by text message using Twilio. The program is written and tested in Ruby. Doubles/mocking are used to avoid sending SMS messages during testing.

Example usage

• If a customer would like to see a list of dishes with prices:

2.4.1 :001 > require './lib/takeaway'
=> true

2.4.1 :002 > takeaway = Takeaway.new

2.4.1 :003 > takeaway.read_menu
 => {"Fish and chips"=>7, "Burger"=>8, "Kebab"=>10, "Pizza"=>12}

• If the customer would like to be able to select some available dishes:

2.4.1 :004 > takeaway.select_dish('burger', 2)
 => 2

2.4.1 :005 > takeaway.select_dish('pizza', 1)
 => 1

• If the customer would like to check the sum of total and see the order

2.4.1 :006 > takeaway.show_order
1. 2x Burger, £8
2. 1x Pizza, £12
Total: £28
 => nil

• Confirm the order with the customer, they enter the total value of the order to place it. The customer then receives a text similar to "Thank you! Your order will be delivered before 19:15"

2.4.1 :007 > takeaway.place_order(28)
SM050dc5c783954e2796a5fc58626cdd9a
 => nil

Requirements

• Ruby 2.4.1
