[tjmaher]

Assignment by Gaurav Parajuli: "For the web page in there please write few unit and at least three JScript/ Java-based selenium test in Nightwatch.".

First time installing and using:

• Material Design Lite: https://getmdl.io/
• WebPack: a module builder: http://webpack.github.io/
• Vue-loader: a loader for WebPack: http://vue-loader.vuejs.org/en/
• Nightwatch: http://nightwatchjs.org/

... but here it goes! I've only used Selenium WebDriver with Java for the past two years at Fitbit. Some API testing. See
