driver.manage().window().maximize() gives exception on Chrome v 57

[Denis]

The selenium code to maximize the Chrome browser no longer version starting from latest Chrome version 57 and gives an exception. I tried with latest version of Selenium and Chromedriver and it still fails. This is a blocker for me. Does anyone have the same issue or can provide a workaround (which does not involve heavy handed Java Robot approach because it is so brittle)?

Code line in question:

driver.manage().window().maximize()

Here is the stack trace exception:

Hi,

Don't use driver.manager().window().maximize() for Chrome. Try the below logic instead -

ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");

WebDriver driver = new ChromeDriver(options);
driver.get(.....);


Cheers, Anish

I have the same issue with chromedriver 2.27+Chrome 57, but after upgrading chromedriver with latest version (2.28),  issue solved. I am not sure why it does not works for your case. You can try delete all extensions from your chrome.

It seems you are using ChromeDriver 2.25.426923, it is too old to support Chrome 57

Best Regards,

You only need to upgrade your  chrome driver 2.29
