Nightwatch v1.3

We're delighted to announce the release of Nightwatch v1.3. Please see the upgrade guide if you are upgrading from a pre v1.0 version.

Up & Running in 2 Minutes:

1. Install Nightwatch from NPM

$ npm install nightwatch --save-dev

2. Install Browser Drivers:

Geckodriver (Firefox):

Geckodriver is the WebDriver service used to drive the Mozilla Firefox Browser.

$ npm install geckodriver --save-dev

Chromedriver:

Chromedriver is the WebDriver service used to drive the Google Chrome Browser.

$ npm install chromedriver --save-dev

or install everything with one line:

$ npm i nightwatch geckodriver chromedriver --save-dev

3. Run a Demo Test:

Nightwatch comes with an examples folder containing a few sample tests.

Below will run a basic test which opens the search engine Ecosia.org, searches for the term "nightwatch", and verifies if the term first result is the Nightwatch.js website.

$ ./node_modules/.bin/nightwatch node_modules/nightwatch/examples/tests/ecosia.js

Windows users might need to run node node_modules/.bin/nightwatch.

Manually Download Browser Drivers

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

• for running tests against the Chrome browser;
• download url: https://sites.google.com/a/chromium.org/chromedriver/downloads.

Starting with version 75, Chromedriver has W3C Webdriver protocol enabled by default. If you'd like to stick to the JSONWire for now adjust the chromeOptions:

desiredCapabilities : {
  browserName : 'chrome',
  chromeOptions: {
    w3c: false
  }
}

GeckoDriver

• for running tests against the Mozilla Firefox browser;
• download url: https://github.com/mozilla/geckodriver/releases.

Selenium Standalone Server

• allows managing multiple browser configurations in one place and also to make use of the Selenium Grid service;
• the selenium server jar file selenium-server-standalone-3.x.x.jar can be downloaded from the Selenium releases page: https://selenium-release.storage.googleapis.com/index.html

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.

Specific WebDriver setup guides can be found on the Docs website. Legacy Selenium drivers setup guides along with debugging instructions can be found on the Wiki.

Examples

Example tests are included in the examples folder which demonstrate the usage of several Nightwatch features.

You can also check out the nightwatch-website-tests repo for example tests against the nightwatchjs.org website.
