ElementNotVisibleException when using a Chrome browser without a browser

Question

When I run a test script in a Chrome browser without a browser, the link to the item is not displayed, it cannot execute linkElement.click(). in head mode, everything is fine. All other data is in stacktrace. Does anyone know what to do, please?

Stacktrace:

An error has occurred: message: the item is not displayed
 (Session information: headless chrome = 60.0.3112.90)

Here is my piece of code:
 icons = nik.elementLeftmenuSportIcons() for i in icons[:-1]: try: i.click()

HTML from the test page: <a href="#" class="default b_futbal gaPageEventElement" data-ga-cat="Sporty" data-ga-action="futbal"> <span class="left-menu-only-large-res">Futbal</span> </a>

Answer 1

I think the problem is that the item doesn’t really appear in the default viewport (600x800) of Chrome headless.

The headless browser window size should be set as an argument when starting chrome. I am using javascript (I think the API is similar to python):

var Options = require('selenium-webdriver/chrome').Options;
var options = new Options();
options.addArguments('headless');
options.addArguments('disable-gpu');
options.addArguments('window-size=1200,1100');

browser = builder.forBrowser('chrome').setChromeOptions(options).build();

Additional Information

webdriver browser.manage().window().setSize(1200,1100); . .

, .

1. Chrome, ( ):

ChromeOptions options = new ChromeOptions()
options.addArguments("headless");
options.addArguments("window-size=1200,1100");
WebDriver driver = new ChromeDriver(options);

2. Chrome:

WebDriver webDriver= new ChromeDriver();
webDriver.manage().window().setSize(new Dimension(1200,1100));

Answer 3

options.addArguments( ' = 1200,1100');

groovy: -

        ChromeOptions options = new ChromeOptions()
        DesiredCapabilities capabilities = DesiredCapabilities.chrome()
        options.addArguments('headless','disable-gpu','--test-type','--ignore-certificate-errors')
        options.addArguments('window-size=1200,1100');
        capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
        capabilities.setCapability(ChromeOptions.CAPABILITY, options)
        driver = {new ChromeDriver(capabilities)}
