There are two main aspects of running NightWatchJS tests in the grid. The first aspect is initiating a test session and the other is running a test in parallel on multiple browsers.

Initiating a Test Session

To initiate a test session and run a NightWatchJS test on the grid, certain capabilities must be specified in the Desired Capabilities object. The capabilities are:

  1. Authentication with NightWatchJS
  2. Cloud URL - the URL of the cloud.

In addition, the NightWatchJS test desired capabilities may include the following capabilities:

  • testName - Specifies the test name. This name will appear in SeeTest Reporter and in the generated report
  • generateReport - By default every NightWatchJS test generates a report and takes screenshots after each command. To disable reports (and screenshots) pass this capability with a false value
  • takeScreenshots - take a screenshot of reports and the device reflection in the Grid page
  • platformName - run the test on the specified platform (Mac, Windows, iOS, etc...)
  • browserName - run the test on the specified browser (default is chrome)
  • browserVersion - run the test on the specified browser version (check which version are supported in your lab)
  • newCommandTimeout - change the default timeout for each command in the test (default is 300 seconds)

  • newSessionWaitTimeout - change the default timeout for creating a new driver (default is 300 seconds)


    In order to use Continuous Testing additional capabilities, you should use the following format:

    testName : 'here is the test name',

If the NightWatchJS test is configured to generate a report when the test is finished a detailed report will be created in SeeTest Reporter.


Below you can find an example written in Javascript specifying the capabilities above.

NightWatchJs - Grid Execution
module.exports = {
  selenium : {
     start_process : false,
     selenium_host : '<cloudurl>',
	 server_path:'/wd/hub',

   },
	
  test_settings : {
      default : {      //default environment
      selenium_port : <port>,
      selenium_host : '<cloudurl>',
      use_ssl : true,		//or false if the cloud doesn't use SSL
      desiredCapabilities : {
			browserName:'chrome',
			platformName:'mac',
            accessKey : '<ACCESS_KEY>',
            testName : 'NighwatchJSTest',
            javascriptEnabled : true,
			takeScreenshots : true,
            newCommandTimeout : 300,
            newSessionWaitTimeout : 300
			}
		}	
	 }	
};
