Scrolling by a certain distance in Java Selenium (using JavaScriptExcecutor)

When testing or automating web applications, there are times when you need to scroll the page by a certain distance to interact with off-screen elements or simply to observe the behavior of a website. In this article, we'll discuss how to scroll by a specific distance using Java Selenium.

Scrolling using JavaScript Executor

The JavaScript Executor is a powerful tool in Selenium that allows you to execute JavaScript code directly in the browser. We can use this feature to scroll the page by a certain distance. Here's a code snippet that demonstrates how to achieve this:

JavascriptExecutor js = (JavascriptExecutor) driver;
int x = 0;
int y = 500;
js.executeScript("window.scrollBy(" + x + ", " + y + ");");

In this code snippet, we first cast the WebDriver instance to a JavascriptExecutor. Then, we define the x and y variables, which represent the horizontal and vertical distances we want to scroll, respectively. Finally, we execute the JavaScript code "window.scrollBy(x, y);" to scroll the page by the specified distances.

Here is an example test that uses the above code snippet.

Run Working Example

By using the JavaScript Executor, we can easily and efficiently scroll the web page by a specific distance to interact with elements that are initially off-screen or verify the proper functioning of the website's scrolling features.
