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 :

view plainprint?

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

Here is the sample code using TestNG framework. :

view plainprint?

1. import java.awt.Toolkit;  
2. import java.io.IOException;  
3. import org.openqa.selenium.WebDriver;  
4. import org.openqa.selenium.firefox.FirefoxDriver;  
5. import org.testng.Reporter;  
6. import org.testng.annotations.BeforeTest;  
7. import org.testng.annotations.Test;  
8.   
9. public class MaximizeWindow {  
10.   
11. WebDriver driver;  
12.   
13. @BeforeTest  
14. public void setUpDriver() {  
15. driver = new FirefoxDriver();  
16.       }  
17.     
18.   
19. @Test  
20. public void maximize() {  
21.  //declare varibales for windows  
22. org.openqa.selenium.Dimension defaultDim;  
23. org.openqa.selenium.Dimension maximizeDim;  
24. //Load google website on browser  
25. driver.get("http://google.com");  
26. //Display the current screen dimensions  
27. defaultDim=driver.manage().window().getSize();  
28. System.out.println("screenHeight before maximizing"+defaultDim.getHeight());  
29. System.out.println("screenWidth before maximizing"+defaultDim.getWidth());  
30. //maximize the window using webdriver method  
31. driver.manage().window().maximize();  
32. //Display the maximized window dimensions  
33. maximizeDim=driver.manage().window().getSize();  
34. System.out.println("screenHeight after maximizing:"+maximizeDim.getHeight());  
35. System.out.println("screenWidth after maximizing:"+maximizeDim.getWidth());  
36.   
37.       }  
38.   
39.
