How to Enable Web Elements for Automation Tes

Flutter has become a popular framework for building web applications due to its fast performance and expressive UI. However, when it comes to automated testing with Selenium, especially for scrolling actions, it can get a bit tricky. In this guide, I’ll show you a quick and reliable way of scrolling within a Flutter web app using Java and Selenium.
We’ll cover how to use the JavaScript Executor to achieve smooth scrolling to specific elements on the page.
Scrolling in a Flutter web app isn’t straightforward because the usual Selenium scrolling methods might not work as expected. Flutter manages its own rendering and might not expose the DOM elements in a way traditional web pages do. However, using JavaScript execution, we can overcome this limitation.
JavaScript Executor
allows us to run JavaScript code within the context of the browser. This is especially useful for manipulating the page directly, such as scrolling to a particular element.ScrollHelper.java
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
public class ScrollHelper {
public static void scrollToElement(WebDriver driver) throws InterruptedException {
// Cast the driver to JavascriptExecutor
JavascriptExecutor js = (JavascriptExecutor) driver;
// Find the element using its CSS selector
WebElement ele = driver.findElement(By.cssSelector("flt-semantics[aria-label={YOUR_SELECTOR}]"));
// Scroll to the element
js.executeScript("arguments[0].scrollIntoView({ behavior: 'smooth', block: 'start' });", ele);
// Wait for the scroll action to complete
Thread.sleep(2000);
}
}
JavascriptExecutor
to execute JavaScript code.{YOUR_SELECTOR}
with the actual aria-label
of your target element.scrollIntoView
method ensures the element is brought into the viewport with a smooth scrolling behavior. The block: 'start'
option aligns the top of the element with the top of the scrollable area.There you go scrolling in a Flutter web app using Selenium can be achieved with the help of JavaScript execution. By targeting the specific elements and using the scrollIntoView
method, you can ensure that your automated tests interact with the elements correctly. This approach helps overcome the challenges posed by Flutter’s custom rendering behavior.
