Headless chrome docker - maximized window not working

[sridharaiyer]

Hi Tried all this but was not able to get the browser in maximized state in headless running inside docker

class ITests(BaseCase):
    def load_driver(self):
        """
        This function Add custom chrome browser capabilities and to handle PDF File download functionalities
        """
        self.driver.quit()
        chrome_options = webdriver.ChromeOptions()
        chrome_options.add_argument("--use-fake-ui-for-media-stream")
        chrome_options.add_argument("--kiosk-printing")
        chrome_options.add_argument("--kiosk")
        chrome_options.add_argument("--start-maximized")
        chrome_options.add_argument("--headless")
        chrome_options.add_argument("--window-size=1920x1080")
        chrome_options.add_experimental_option("prefs", prefs)
        chrome_options.add_experimental_option(
            "excludeSwitches",
            ["enable-automation", "enable-logging", "enable-blink-features"])
        self.driver = webdriver.Chrome(options=chrome_options)

A step is failing due to the screen not maximized as the elements in a table are getting out of the view. I don't want to use the javascript scroll into view as I want the application to be automated when in a maximized state.

@sridharaiyer In your code, you seem to be setting both --start-maximized and --window-size, but those would likely conflict because you can’t set both of them at the same time. Also, there’s an existing Dockerfile: https://github.com/seleniumbase/SeleniumBase/blob/master/Dockerfile. And you can set maximized windows for tests from the command-line with “--maximized”.

Hi, I should have clarified more. So here you go -

Here is my selenium and Seleniumbase version selenium==3.141.0 seleniumbase==1.63.9

The issue is, even before I run in Docker, the test is failing even in local headless execution.

Yes, I am using the docker file taken from your repository, with a few additions. Here is my dockerfile.

Yes I tried the command line --maximize-window option as well. It didn't maximize my application.

However, my application is not being maximized. Here is a screenshot. As you can see, some of the buttons are one below the other and in the web table 'Matching Vehicles' I am expecting to see a link towards my right corner but it is not showing in view as the screen is not maximized. That's where my script is failing.

Have you tried using the latest version of SeleniumBase? (2.4.14) Your version is a year old and is missing important updates.

[mdmintz]

And have you tried using self.set_window_size(width, height) in your test with large dimensions?

[mdmintz]

Three different ways to solve your issue:

1. Upgrade to version 2.4.14 (your version was 1.63.9)
2. self.set_window_size(width, height) with large dimensions.
3. Use a self.js_click(selector) instead of a regular self.click()

Closing this again, as one of the above 3 things should have resolved your issue.
