How to perform Page scrolling in Selenium WebDriver

How to do it?

1)Create ScrollBar class under any named package with @BeforeTest and @Test TestNG annotations as below.

public class ScrollBar {

public static WebDriver driver;
public static String baseUrl;

@BeforeTest
public void setup(){

driver = new FirefoxDriver();
driver.manage().window().maximize();
baseUrl="http://www.softwaretestutorials.blogspot.in";

}

@Test
public void pageScroll(){
driver.navigate().to(baseUrl);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

//Now we need to scroll down the page in order to see all the searched links
//Here we are using javascriptExecutor for page scroll down/Up
JavascriptExecutor scpag = (JavascriptExecutor)driver;
scpag.executeScript("window.scrollBy(500,5000)", "");
}
}

 2)Creating 

JavascriptExecutor scpag = (JavascriptExecutor)driver;
JavascriptExecutor object to call ScrollBy(x,y) for coordinates to scroll the page.

Now we need to scroll down the page in order to see all the searched links,Here we are using javascriptExecutor  Interface for page scroll down/Up.

JavascriptExecutor scpag = (JavascriptExecutor)driver;
scpag.executeScript("window.scrollBy(500,5000)", "");

3)Execute the Test script by right click on Script then Run as - TestNG Test,Browser will open specified URL and it will scroll down the page until specified co ordinates in ScrollBy(x,y).

scpag.executeScript("window.scrollBy(500,5000)", "");
