It uses the W3C WebDriver API (it was called Selenium WebDriver formerly) behind the scenes to open the web browser to perform operations and assertions on DOM elements. It is a great tool if you want to use a browser to test your Nuxt apps.

1. Install Nightwatch via npm and save it to the devDependencies option in the package.json file:

$ npm i nightwatch --save-dev

2. Install GeckoDriver via npm and also save it to the devDependencies option in the package.json file:

$ npm install geckodriver --save-dev

Nightwatch relies on WebDriver, so we need to install a specific WebDriver server depending on your target browser – for example, if you want to write tests against Firefox only, then you will...
