Here, we discuss that how to resize the browser's width and height in Selenium WebDriver. It allows to resize and also maximize the window from its API. In this, Dimension Class helps to resize and declare the object by initializing the width and height.

Also, we need to import:

'import org.openqa.selenium.Dimension'

Steps to be automated:

• Launch the browser
• Open your site
• Navigate to your required location
• Resize the browser width and height

WebDriver Code goes as below:

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.Dimension;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class ResizeWindow {

	public static void main(String[] args) throws InterruptedException {
		
        WebDriver driver = new FirefoxDriver();
		
        driver.get("http://google.com");
        
		driver.manage().timeouts().implicitlyWait(20L, TimeUnit.SECONDS);
		driver.manage().window().maximize();
		
		WebElement textField = driver.findElement(By.xpath(".//*[@id='sb_ifc0']"));
		textField.click();
		textField.sendKeys("testing");
		
		driver.findElement(By.xpath(".//*[@id='sblsbb']/button")).click();
		
		Thread.sleep(3000);
		
        System.out.println(driver.manage().window().getSize());
		Dimension d = new Dimension(420,600);
		
		driver.manage().window().setSize(d);System.out.println(driver.manage().window().getSize());
		
		Dimension d1 = new Dimension(520,700);
		driver.manage().window().setSize(d1);

	}
