Maximize browser window using webdriver

There are times when we want to to maximize the browser window during the execution of our script .For this purpose webdriver providers a built-in method and here is the syntax :

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

Here is the sample code using TestNG framework. :

import java.awt.Toolkit;
import java.io.IOException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Reporter;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class MaximizeWindow {

WebDriver driver;

@BeforeTest
public void setUpDriver() {
driver = new FirefoxDriver();
      }
  

@Test
public void maximize() {
 //declare varibales for windows
org.openqa.selenium.Dimension defaultDim;
org.openqa.selenium.Dimension maximizeDim;
//Load google website on browser
driver.get("http://google.com");
//Display the current screen dimensions
defaultDim=driver.manage().window().getSize();
System.out.println("screenHeight before maximizing"+defaultDim.getHeight());
System.out.println("screenWidth before maximizing"+defaultDim.getWidth());
//maximize the window using webdriver method
driver.manage().window().maximize();
//Display the maximized window dimensions
maximizeDim=driver.manage().window().getSize();
System.out.println("screenHeight after maximizing:"+maximizeDim.getHeight());
System.out.println("screenWidth after maximizing:"+maximizeDim.getWidth());

      }


  }

Last but not the least

Belated Happy New Year All..!!

Have fun..!! :)
