The end goal of the Takeaway Challenge is to build a program that users can use to order a takeaway via text message. Once their order is placed they will receive a confirmation text with their order details. The API used is Twilio.
Current state of this program is that a customer is able to see a list of dishes with with their respective prices.
- So far I have 3 separate classes for 3 objects. Menu, Order, and Takeaway.
As a customer
So that I can check if I want to order something
I would like to see a list of dishes with prices
As a customer
So that I can order the meal I want
I would like to be able to select some number of several available dishes
As a customer
So that I can verify that my order is correct
I would like to check that the total I have been given matches the sum of the various dishes in my order
As a customer
So that I am reassured that my order will be delivered on time
I would like to receive a text such as "Thank you! Your order was placed and will be delivered before 18:52" after I have ordered
:001 > require './lib/takeaway.rb' => true 2.2.3 :002 > require './lib/menu.rb' => true 2.2.3 :003 > require './lib/order.rb' => true
...
Create new menu with dishes
menu = Menu.new("patties" => 2, "ackee" => 5)
Place the order by giving the list of dishes, their quantities and a number that should be the exact total. If the sum is not correct the method should raise an error, otherwise the customer is sent a text saying that the order was placed successfully and that it will be delivered 1 hour from now, e.g. "Thank you! Your order was placed and will be delivered before 18:52".
The text sending functionality should be implemented using Twilio API. You'll need to register for it.
Use the twilio-ruby gem to access the API
Use the Gemfile to manage your gems Make sure that your Takeaway is thoroughly tested and that you use mocks and/or stubs, as necessary to not to send texts when your tests are run
However, if your Takeaway is loaded into IRB and the order is placed, the text should actually be sent
