driver.manage().window().maximize() issue with ChromeDriver 2.33

by

There are exactly 2 issues.

  1. As you mentioned, you have installed latest chromedriver (v2.33) but the log printed below says Driver info: chromedriver=2.25.426923, this issue must be addressed first. You can consider to manually kill all the dangling chromedriver.exe tasks from the Task Manager. Additionally you can consider to use CCleaner to wipe out all the rotten OS stuffs from your system. Take a system reboot if required. Finally ensure that what ever the absolute location of chromedriver.exe you are using within System.setProperty() ensure that the chromedriver binary is of version 2.33.

  2. Finally, it is suggested to use ChromeOptions class to maximize the Web Browser as follows:

    System.setProperty("webdriver.chrome.driver", "C:\\your_directory\\chromedriver.exe");
ChromeOptions opt = new ChromeOptions();
opt.addArguments("disable-infobars");
opt.addArguments("--start-maximized");
opt.addArguments("--disable-extensions");
WebDriver driver = new ChromeDriver(opt);
driver.get("https://google.com");

  3. Here are some of the alternatives which may solve your question:

    • Using maximize() from WebDriver.Window interface :

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

    • Using setSize(Dimension targetSize) from WebDriver.Window interface:

      driver.manage().window().setSize(new Dimension(800, 600));

    • Using addArguments("--start-maximized") through ChromeOptions:

      chromeOptions.addArguments("--start-maximized");

    • Using addArguments("--window-size=1920,1080") through ChromeOptions:

      chromeOptions.addArguments("--window-size=1920,1080");

    • Using executeScript() from JavaScriptExecutor interface:

      ((JavaScriptExecutor)driver).executeScript("window.resizeTo(1024, 768);");
