Headless Nightwatch Tests

Waltir | 2019-05-02

The Nightwatch documentation unfortunately does not cover how to run your tests in a headless mode so I thought it would be worth writing a small post about it. For those of you that are not familiar with the term ‘headless’ it simply means running a automated browser window that does not physically appear anywhere on your machine.

To enable headless this headless mode you’ll want to add ”headless” to your ”chromeOptions” like so:

      
        // The environment below is named 'headless' and is located in our nightwatch.conf.js file.
      
        "headless": {
      
              "desiredCapabilities": {
      
                "chromeOptions": {
      
                  "args": [
      
                        "headless", // This is the line that tells nightwatch to run in a headless mode
      
                  ],
      
                    },
      
                    "browserName": "chrome",
      
                "javascriptEnabled": true 
      
          }
      
        }

That’s all it takes to initiate a headless mode in Nightwatch. Hopefully this is able to help some of my fellow Nightwatch users out.
