Adding Sinon to WebPack

• Open your project (if you're using WebPack, obviously)

• In your tests, require Sinon: var sinon = require('sinon');

Picking A Project to Work On

• Find a Repo that is primarily written in a language you're comfortable with.
  • Check out 24pullrequests.com
  • Talk to mentors that regularly contribute to open source for suggestions
  • Think about tools you already use like rspec or minitest.
  • Browse around Github
• Avoid 'dead' repos - look at open PRs for the project - if a ton unmerged, project may be dead. Also look at stars for the repo and last commit date on master.
• Look at the open issues for ones you can help with
• Look at coverage reports and builds for areas that are untested
• Fork the repo

Module 4 Cheatsheet

Points

To graduate from Module 4 you will need to get ~80% of the total assigned points and pass your portfolio review. There will be ~1250 total points.

Everyone should have access to a google drive spreadsheet that lists where you're at in the pointwise.

If you don't have a link or the magic of google drive is on the fritz and your link isn't working, give us a shout.

When you start working with WebPack for GameTime, you'll notice that you can't just define a variable in one file and find it in another as easily as you can in Rails.
