Page Scroll using Selenium WebDriver

Using JavaScript


Scroll Down:

import org.openqa.selenium.JavascriptExecutor;
WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("scroll(0, 250)"); //y value ‘250‘ can be altered

Scroll up:

JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("scroll(250, 0)"); //x value ‘250‘ can be altered

Scroll bottom of the Page:

JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("window.scrollTo(0,Math.max(document.documentElement.scrollHeight,document.body.scrollHeight,document.documentElement.clientHeight));");
(or)
Actions actions = new Actions(driver);
actions.keyDown(Keys.CONTROL).sendKeys(Keys.END).perform();

Full scroll to bottom in slow motion:

for (int second = 0;; second++) {
        if(second >=60){
            break;
        }
            ((JavascriptExecutor) driver).executeScript("window.scrollBy(0,400)", ""); //y value ‘400‘ can be altered
            Thread.sleep(3000);
}
(or)
JavascriptExecutor jse = (JavascriptExecutor)driver;
for (int second = 0;; second++) {
        if(second >=60){
            break;
        }
            jse.executeScript("window.scrollBy(0,800)", ""); //y value ‘800‘ can be altered
            Thread.sleep(3000);
}

Scroll automatically to your WebElement:

Point hoverItem =driver.findElement(By.xpath("Value")).getLocation();
((JavascriptExecutor)driver).executeScript("return window.title;");    
Thread.sleep(6000);
((JavascriptExecutor)driver).executeScript("window.scrollBy(0,"+(hoverItem.getY())+");"); 
// Adjust your page view by making changes right over here (hoverItem.getY()-400)
(or)
((JavascriptExecutor)driver).executeScript("arguments[0].scrollIntoView();", driver.findElement(By.xpath("Value‘)]")));
(or)
WebElement element = driver.findElement(By.xpath("Value"));
Coordinates coordinate = ((Locatable)element).getCoordinates(); 
coordinate.onPage(); 
coordinate.inViewPort();
