Nightwatch: chromeOptions "start-maximized" or "start-fullscreen" doesn't work with "--headless" arg

Created on 21 May 2020 · 8Comments · Source: nightwatchjs/nightwatch

Hello!

chromeOptions "start-maximized" or "start-fullscreen" doesn't work with "--headless" arg, but works fine without "--headless" arg.

This is part of nightwatch.conf.js, with which problem is reproduced:

desiredCapabilities: {
    browserName: "chrome",
    chromeOptions: {
        args: [
            "start-maximized",
            "--headless"
        ]
    }
}

This is simple test for checking window size:

test (browser) {
    browser.windowSize("current", function(result) {
        console.log(result.value);
    });
}

In this case in console:
{ height: 600, width: 800 }

Buf after removing "--headless" from args of chromeOptions I see such (right) output in console:
{ height: 1026, width: 1696 }

And additionally I've saved screenshots in two scenarios. And here also the same result.

nightwatch v1.3.5
chromedriver v81.0.0
node.js v12.16.2
npm v6.14.4

We need verbose logs as well, in this case the chromedriver log also. It might also be a limitation of chromedriver headless mode implementation. Have you tried the same with Firefox?

2 log files are attached.
nightwatch.log
chromedriver.log

As I understand Firefox doesn't support "start-maximized" or "start-fullscreen" or something similar. If so, then I can't test this with Firefox. Or maybe you can explain how to do this with Firefox?

Could you post the logs inline please, as per contributing guidelines?

Edited first message by adding logs inline. Please, check.

Adding the argument --window-size=1920,1080 when running in headless mode is a work-around worth considering.

Based on the above GitHub discussions, it looks like chromeOptions is only recognized in Chrome driver versions earlier than Chrome 75, so we need to update to use the goog: prefix to properly pass in arguments.

Try this (irrelevant config was left out, but you get the idea)

{
  "test_settings": {
    "default": {
      "desiredCapabilities": {
        "browserName": "chrome",
        "goog:chromeOptions": {
          "w3c": false,
          "args": [
            "disable-gpu",
            "headless",
            "window-size=1920,1080",
            "disable-dev-shm-usage"
          ]
        }
      }
    }
  }
}
