Nightwatch.js

Nightwatch.js is an automated, easy to use End-to-End testing framework written in Node.js and using the W3C WebDriver API. It uses the WebDriver API to drive browsers, enabling commands and assertions on DOM elements.

Nightwatch.js is used for end-to-end testing of web applications and websites, as well as for Node.js unit and integration testing. It offers a clean yet powerful syntax for quick and easy writing of tests, a built-in command-line test runner, continuous integration and more. It's also easy to extend so you can implement custom commands and assertions.
