JavaScript executor not working with Selenium interaction

[Yuriy]

Hello!

Before I execute the test, I run the following code from init.js file as Selenium interaction:

driver.findElement(By.id("truste-consent-button")).click();

((JavascriptExecutor)driver).executeScript("window.scrollBy(0,400)");

On the first line I locate and click the button to accept use of cookies (required by the site under test)

On the second line I try to scroll the window down by 400 pixels.

My test file in Galen is:

Ads: Site Home

    ${base_url}/ 768x1024

        run init.js        

        wait 20s

        check home.spec

But the init.js fails on the second line with the following error message:

EvaluatorException: missing ) in parenthetical (init.js#2)

What's wrong with my init.js code? I'm trying to use JS code from within WebDriver to scroll the page. Or is there a better solution?

Hi,

the second line looks more like a Java code. In JavaScript you don't care about the types so you don't have to cast objects to specific types to get their methods. Just use this:

driver.findElement(By.id("truste-consent-button")).click();
driver.executeScript("window.scrollBy(0,400)");

Thanks! It works!
