To use the tests, you will need to install Node -- you can do this via the download page or using Homebrew if you are on a Mac.
Note that on Windows, there are some reports that you will need to restart after installing Node
run:
npm install
npm install -g grunt-cli
grunt develop
You can then view the tests in your browser at http://localhost:4444.
When you visit that page, all of the tests should be failing; your job is to
get the tests to pass. To do this, you'll need to refer to the tests in the
files in the tests/app directory, and edit the files in the app/ directory.
Once you update a test, you can reload the test page in the browser to see
whether it worked.
You can also run (most of) the tests on the command line:
npm test
