Chrome Setup

Running tests in Chrome is possible with the aid of ChromeDriver.

Getting started

1. Download ChromeDriver - download the latest version of the ChromeDriver for your platform from the [Downloads page] (http://chromedriver.storage.googleapis.com/index.html).

2. Configure the path - either add the path to the ChromeDriver binary to the system PATH or set the location in your nightwatch.json, under the selenium options like so:

"selenium" : {
  ...
  "cli_args" : {
    "webdriver.chrome.driver" : "/path/to/chromedriver"
  }
}

Chrome Capabilities

This is a list of all the Chrome-specific desired capabilities, which all are under the ChromeOptions dictionary.

Name	Type	Default	Description
args	array of strings		List of command-line arguments to use when starting Chrome. Arguments with an associated value should be separated by a '=' sign (e.g., ["start-maximized", "user-data-dir=/tmp/temp_profile"]). See below for usage.
binary	string		Path to the Chrome executable to use (on Mac OS X, this should be the actual binary, not just the app. e.g., '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome')
extensions	array of strings		A list of Chrome extensions to install on startup. Each item in the list should be a base-64 encoded packed Chrome extension (.crx)

For a complete list of supported Chrome capabilities please refer to ChromeDriver Capabilities
