How to maximize the browser window in Selenium WebDriver (Selenium 2) using C#?

Question

Is there any way to maximize the browser window using WebDriver (Selenium 2) with C#?

Answer 1

Java

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

---

Python

driver.maximize_window()

---

Ruby

@driver.manage.window.maximize

OR

max_width, max_height = driver.execute_script("return [window.screen.availWidth, window.screen.availHeight];")
@driver.manage.window.resize_to(max_width, max_height)

OR

target_size = Selenium::WebDriver::Dimension.new(1600, 1268)
@driver.manage.window.size = target_size

Answer 2

If you are using the Chrome Driver you can set the capabilities

    var capabilities = new DesiredCapabilities();

    var switches = new List<string>
                       {
                           "--start-maximized"
                       };

    capabilities.SetCapability("chrome.switches", switches);

    new ChromeDriver(chromedriver_path, capabilities);

There is a function that you can use to maximize the window in Python which is window_maximize(). And this is how I'm using it.Hope this helps -

from selenium import selenium
sel = selenium('localhost', 4444, '*firefox', 'http://10.77.21.67/')
sel.start()
sel.open('/')
sel.wait_for_page_to_load(60000)
#sel.window_focus()
sel.window_maximize()
png = sel.capture_screenshot_to_string()
f = open('screenshot.png', 'wb')
f.write(png.decode('base64'))
f.close()
sel.stop()

You can use Selenium Emulation in WebDriver:

selenium = new WebDriverBackedSelenium(driver,url);
selenium.windowMaximize();

Answer 5

I used this solution

            OpenQA.Selenium.Chrome.ChromeOptions chromeoptions = new OpenQA.Selenium.Chrome.ChromeOptions();
            chromeoptions.AddArgument("--start-maximized");
            OpenQA.Selenium.Chrome.ChromeDriver chrome = new OpenQA.Selenium.Chrome.ChromeDriver(chromeoptions);

The following Selenium Java code snippet worked for me:

driver.manage().window().setPosition(new Point(0,0));
java.awt.Dimension screenSize = java.awt.Toolkit.getDefaultToolkit().getScreenSize();
Dimension dim = new Dimension((int) screenSize.getWidth(), (int) screenSize.getHeight());
driver.manage().window().setSize(dim);
