This is a simple demo for running tests using Cucumber and Nightwatch. There is also a tutorial available.
Make sure you have all dependencies installed with npm install.
You can then run tests with npm test.
If you already have chromedriver installed (via Homebrew, for example) then you
may see an error when installing chromedriver with npm install. You can point
webdriver.chrome.driver in the config file to your chromedriver path (/usr/local/bin/chromedriver).
Make sure to comment out const chromedriver = require('chromedriver'); if you do this.
