This repository provides you with a very basic framework for developing a simple system for tracking customers and allowing things to be rented out (such as videos)
The primary goal is to learn mocking, so apply this as you develop the application through TDD.
You are tasked with creating a system that can manage an inventory of rentable items and take care of allowing them to be rented out to people, with an associated charge for the permitted duration of rental, plus any penalty applicable to the rental.
Focus on producing (via TDD) a working implementation of a class to track inventory that is also able to assign a rental into a customer.
