Maximize Browser Window with Chrome doesn't work as expected on OSX

See original GitHub issue

Maximize Browser Window keyword only maximizes browser window height or doesn’t even do that at all (looks like Chrome opens by default with max height). When setting window size with Set Window Size keyword browser’s width and height changes correctly. So it looks like Maximize Browser Window is partially or completely broken with Chrome on OSX.

OS: macOS Sierra Chrome 53 & chromedriver 2.24

robotframework==3.0 robotframework-selenium2library==1.8.0 selenium==2.53.6 (tested also with 3.0.1)

I was facing the same issue specifically for mac. Following worked fine for me.

JavascriptExecutor jse = (JavascriptExecutor)driver; String screenWidth = jse.executeScript(“return screen.availWidth”).toString(); String screenHeight = jse.executeScript(“return screen.availHeight”).toString(); int intScreenWidth = Integer.parseInt(screenWidth); int intScreenHeight = Integer.parseInt(screenHeight); Dimension d = new Dimension(intScreenWidth, intScreenHeight);
driver.manage.window.setSize(d);

The root problem appears to be that maximize in Chromium is not maximize. https://bugs.chromium.org/p/chromium/issues/detail?id=14185 So even starting Chrome with --start-maximized doesn’t help. If Set Window Size is not an alternative for you, here is a workaround that runs Chrome full screen:

    ${options}  Evaluate  sys.modules['selenium.webdriver'].ChromeOptions()  sys
    Call Method  ${options}  add_argument  --start-fullscreen
    Create WebDriver  Chrome  chrome_options=${options}
