Mouse scroll down using Selenium WebDriver (a.k.a. Selenium 2.0) - JAVA

Question

I am trying to do a mouse scroll in my automation testing (selenium webdriver). My page have loads of data where it take time to load all the datum.

My Requirement: I have a consolidated table with set of datum, where those records are displayed from the set of values that get displayed in the bottom of my page.

I am validating whether both the values are equal, for that I need the page to be completely scrolled to evaluate the same.

I used the below code:

Javascript jse = (Javascript)driver;
jse.executescript("scroll(0, 9000)");

This doesn't help it scrolled only half of the datum so my test get fail.

Suggestions please...

Answer 1

We can use JavascriptExecutor to achieve this. Following is an example which will scroll this page from top to bottom:

WebDriver driver = new ChromeDriver();
driver.get("http://stackoverflow.com/questions/25363023/mouse-scroll-down-using-selenium-webdriver-2-0-java");

JavascriptExecutor jse = (JavascriptExecutor) driver;
jse.executeScript("window.scrollTo(0,document.body.scrollHeight);");

To use above code please import below utilities:

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

Lemme know if this helps!

Answer 2

Use these imports:

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;

Mouse Scroll Down:

JavascriptExecutor Scrool = (JavascriptExecutor) driver;
Scrool.executeScript("window.scrollBy(0,300)", "");
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

You can find elements after Scrolling:

driver.findElement(By.xpath(""));

Mouse Scroll up:

JavascriptExecutor Scrool = (JavascriptExecutor) driver;
Scrool.executeScript("window.scrollBy(0,-300)", "");
