Instructions

Run tests with rake test

New since last review!

As instructed, the functionality has been expanded.

Here is a summary before you dive in:

• Tests are now run via rake test, and the main.rb scratchpad has been removed.
• Product information is now stored in a Product class that can be instantiated with an ID, price, and discount if applicable. There is a Shop class that keeps track of these.
• The Checkout class still exists, but adding and removing items can now be done in bulk. We still use product IDs when doing this.
• Discount logic is encapsulated in a class. Each product can have one kind of discount at the moment, chosen from "Buy X get one free" or "Bulk discount when X are purchased" in order to satisfy requirements.
• New test classes have been created as appropriate, although the bulk of the tests are still against the Checkout class.
• See the setup method in tests/checkout_test.rb for a full example of how a shop might be configured.
