In this post, we see how to Resize Browser Window using Selenium WebDriver. In some cases, we may need to resize browser window to some fixed dimensions, particularly when we are testing for responsive web design because we need to check to see how the different elements on the page render when we resize the browser window. Using Selenium WebDriver we could Resize Browser Window size. It allows resizing and maximizing window natively from its API.

To resize browser window to particular dimensions, we use ‘Dimension’ class to resize the browser window.

We know how to maximize the browser window to the maximum width and height of the screen.

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

The below code opens the SoftwareTestingMaterial website and then set the browser window size to 480*620 .

package dummy;

import org.openqa.selenium.Dimension;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;

public class ResizeBrowser {
	
    @Test	
    public void launchBrowser() {
    	System.setProperty("webdriver.gecko.driver","D://Selenium Environment//Drivers//geckodriver.exe");
        WebDriver driver = new FirefoxDriver();
        driver.navigate().to("https://www.softwaretestingmaterial.com");
        System.out.println(driver.manage().window().getSize());
        //Create object of Dimensions class
        Dimension d = new Dimension(480,620);
        //Resize the current window to the given dimension
        driver.manage().window().setSize(d);
        System.out.println(driver.manage().window().getSize());
     }	
}
