"""Unit test for the module gym.

This module illustrates what a unit test should look like.
It is doing some slightly fancier stuff than what we saw
in lecture, to give you an idea of how using test cases
in a unit test framework can allow you to do somewhat
more complexly things in a succinct fashion."""
