Unable to resize or move Google Chrome browser window using WebDriver

[Michael Cohen]

Hi,

I'm trying to use the latest WebDriver (v2.15.dev) to resize and move
a browser window. When I try to execute the following (in Ruby), the
Firefox browser responds to the commands but Google Chrome does not:

driver.manage.window.resize_to 1024, 768
driver.manage.window.move_to 0, 0

WebDriver will give me the follow error message when I use Chrome:

selenium-webdriver-2.15.1.dev/lib/selenium/webdriver/remote/
response.rb:52:in `assert_ok': unknown error, status=405: ["GET",
"HEAD", "DELETE"] (Selenium::WebDriver::Error::WebDriverError)

Looking into the issue some more, it appears that Google Chrome in
fact does not support either the window.moveTo and window.resizeTo
commands [1, 2]. Despite Google's decision for the omission, it does
not hold in the case of testing a web app and making sure it works as
expected when displayed in different window sizes.

Will the Google Chrome driver be updated so that it at least provides
support to actually resize and move the browser window? Or is there
some other way of resizing Google Chrome using WebDriver that I'm
overlooking?

Michael,

It sounds like you are trying to maximize the window. I ran into the
same issues with javascript resizeTo() and moveTo() as your research
indicates. I believe these commands will only work with a javascript
created window that has no additional tabs.

If maximizing is your goal, that can done with chrome command line
flags (or switches). Here's my Java example, would have to apply
appropriate Ruby syntax:

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--start-
maximized"));
driver = new ChromeDriver(capabilities);

which on the command line would be equivalent to launching chrome
like : /path/to/chrome.exe --start-maximized

Hope that helps.

The ChromeDriver doesn't currently support this API - I've filed a
tracking bug for this:
https://code.google.com/p/selenium/issues/detail?id=3145

The --start-maximised flag is a good workaround for now

@Luke: I'm working with a hi-res monitor, so 1024x768 is just one of
many resolutions I'm using to simulate a maximized browser window.
Using the --start-maximized argument is a nice temporary solution, but
it will also require changing the screen's actual resolution.
Therefore, having the ability to actually set the browser's size and
not just maximizing it to the actual screen dimensions is still very
important.

@Daniel: Excellent, thanks a bunch!

This is already tracked in the Chromium tracker:

@Jari: Is that the correct link? I took a look but the issue is the
following: Crbug's comment text area eats mouse click.

Is that a separate issue from http://code.google.com/p/chromium/issues/detail?id=2709

Although that seems RC specific, but i can't tell.

[Lukus]

Well, if anyone can get it done it would be the pull of Selenium, but
last I checked these functions don't work even in pure javascript for
Chrome, and it isn't high on on the developer's priority list. I
looked this up over half a year ago when still working with RC.
WebDriver doesn't have application control either, though Chrome is
working more with webdriver as a standard, but still could be a while
for this.

In the meantime, you'd have to develop something that can resize the
window on the OS side or via a plugin. Also, consider that resolution
can be changed for the OS versus just the window. My experience is
that selenium can not do everything a test suite might need, so my
code contains work-arounds as necessary, like in this case, launching
VMware instances at certain resolutions, or using Java's Robot to send
mouse clicks, and Process to run batch scripts that can get things
done. Just food for thought. Good luck.

I have had to direct my html files to Safari, which handles "resizeto" and "move to".  Neither FireFox nor Google Chrome handles these Javascript commands correctly.

James,

You should update to a new version of Selenium. This thread is over 2 years old and the known issue was fixed and closed a while ago. If I enter the following it works:

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :chrome

driver.manage.window.resize_to 800,600

driver.manage.window.move_to 0,0

This will open a chrome browser, resize it to 800 by 600 then move it to the upper left corner of the screen.
