void setSize() – This method is used to set the size of the current browser.

Dimension getSize() – This method is used to get the size of the browser in height and width. It returns the dimension of the browser.

Point setPosition() – This method is used to set the position of the current browser.

Example: Resize a browser using selenium web driver

a) Selenium script with explanation.

Script Description : In the below Selenium script shown the resize of the browser using testNG framework , steps of the scenario are :

1. Open the chrome browser .
2. Launch the site .
3. Wait for a few seconds as to view the resize action .
4. Close the browser.

import org.openqa.selenium.Dimension;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class Resize {

	public static void main(String args[]) throws InterruptedException
	{
		WebDriver driver;
	
		System.setProperty("webdriver.chrome.driver","E://Selenium//Selenium_Jars//chromedriver.exe");
		 driver= new ChromeDriver();
 		 
         // Launch the application
     	 driver.get("https://www.guru99.com/");
     	 
     	Dimension d = new Dimension(300,1080);
     	//Resize current window to the set dimension
     	   driver.manage().window().setSize(d);
     	        
     	 //To Delay execution for 10 sec. as to view the resize browser
     	 Thread.sleep(10000);
     	       
     	 //Close the browser
     	 driver.quit();
	}	
}

b) Output Analysis

Opened the chrome browser , resized the browser, wait for a few seconds and closed the browser.

public class Minimize {

	public static void main(String args[]) throws InterruptedException
	{
		WebDriver driver;
	
		System.setProperty("webdriver.chrome.driver","E://Selenium//Selenium_Jars//chromedriver.exe");
		 driver= new ChromeDriver();
 		 
         // Launch the application
