Testing Template Repo

Basic Setup

1. Copy this repo. Either do it manually (rm -rf .git && git init in the copied directory), or by forking and renaming on GitHub, or (best of all) creating a new repo on GitHub and choosing this repo as its template.
2. Go into the repo and run npm i to install the jest testing framework.
3. Run npm test in a terminal, preferably a full-screened one for a proper display of your test results. Or, alternately, use an in-line test runner if you have one.
4. Write some tests in main.test.js that will test your student's code, and then write the code in main.js that your students should write. Don't forget to add anything you want tested to the module.exports object in main.js, and declare them in main.test.js in the require deconstruction curlies.
5. Delete your code; that's the student's job now. Or, even better: make this repo a solutions repo for a repo you'll now make without the solution in it.
6. DELETE THIS README! These directions are not for your students. Even better: rewrite this readme to be directions that are for your students.
