A series of examples on how to TDD React

1. install nvm

• Grab an editor or IDE. I recommend Webstorm, Atom, and VIM, in that order.
• git clone ...
• nvm install 4 OR if v4 of node.js is installed, nvm use
• npm i

Each section is broken out into its own folder, starting with basics. What you'll find there is the finished example. I am experimenting with using the commit history and comments to drive the guide itself. Feedback on whether this works or not would be appreciated.

Each commit that is suffixed with "- red" can be checked out separately to examine the failing test. Each commit that is suffixed with "- green" shows how I finally passed the failing assertion.

Looking at the history for each section will show you only the steps needed to drive that part of the application.

• Avoid the need for runners and browsers
  • Achieved by using jest and react-testing-library

• Basics - Steps for TDD'ing the simplest of React components: An unordered list of items. Start here if you're not familiar with TDD'ing React and want to see a simple introduction.
  • Running version
