    Nightwatch.js

    Browser automated testing done easy.

    Write End-to-End tests in Node.js quickly and effortlessly that run against a Selenium/WebDriver server.

    Browser Automation

    Nightwatch.js is an easy to use Node.js based End-to-End (E2E) testing solution for browser based apps and websites. It uses the powerful W3C WebDriver API to perform commands and assertions on DOM elements.

    安装

    https://github.com/nightwatchjs/nightwatch

    1. Install Nightwatch

    Install Node.js (together with the NPM tool) by following instructions available on nodejs.org.

    From NPM:

    $ npm install nightwatch

    From GitHub:

    $ git clone https://github.com/nightwatchjs/nightwatch.git
    $ cd nightwatch
    $ npm install

    2. Download WebDriver

    Nightwatch uses a WebDriver compatible server to control the browser. WebDriver is a W3C specification and industry standard which provides a platform and HTTP protocol to interact with a browser.

    Nightwatch includes support for automatically managing the following services:

    ChromeDriver

    Selenium Standalone Server

    It's important to note that, while the Selenium Server was required with older Nightwatch versions (v0.9 and prior), starting with version 1.0 Selenium is no longer necessary.
