The test suite is located in ./spec. Before you begin anything, run bundle install.

To run the tests in the terminal, run rspec --format documentation. Every time you make a change and save your files, you will need to manually re-run the tests. When you start, all of the tests will be failing; your goal is to make as many pass as you can in the hour provided.

HINT: read the output of the failing tests.

This checkpoint is divided into three sections:

• Fundamentals in fundamentals.rb
• Enumerables in enums.rb
• Object Oriented Ruby in oop.rb

Each section has a series of prompts written in inline-comments. Write the Ruby necessary to complete each prompt.

Make a commit after you complete each section.
