actions.moveToElement in Selenium does not scroll

[rscwcd]

Hi,

After upgrading our project to use gecko driver(Version "geckodriver-v0.16.0-win64") and FF 53.0, found that a feature to scroll down the page is not working. Tried many different techniques but didn't find any way to scroll the page to go through required element. We are using below code to go through this:

public T scroll_to_element(By element) {
WebElement webElement = findElement(element);
Actions actions = new Actions(driver);
actions.moveToElement(webElement).perform();
return me();
}

Please advise.

The actions.moveToElement API is a Selenium API and does not correspond to a primitive in the WebDriver specification. I suspect there is a bug with the shim Selenium provide for this.

Could you open a bug with Selenium, and I will keep this open for tracking purposes?

@andreastt : Hi, I have generated a new issue on Selenium Forum with below link

actions.moveToElement in Selenium does not scroll down the page #4148

Is this really a bug in selenium? I run into that issue and the same code in chrome works for me.

Here is the output and stacktrace i got with geckodriver 0.18 and ff55:

@mseele I would say it depends on the interpretation of the specs. Chrome might do an implicit move on a mouse click, while Firefox doesn't. But if you strictly follow the specs, there is no scroll demanded. Therefore I would consider this an upstream bug/missing feature. It has been confirmed by upstream in the linked issue:

w3c/webdriver#1005

[mseele]

I don't see this as "solution". My problem ist: all the "other" browsers (chrome, ie, edge) are working with this code. Firefox worked with the "old" driver and with geckodriver it does not work anymore.

There is no "code" to scroll an element which is out of the viewport into the viewport with geckodriver. Because of this, imho this is a bug for me. How to solve the problem of scrolling an element which is out of the viewport into the viewport with geckodriver?

[SankySyS]

Workaround on Java:

WebElement element = driver.findElement(locator);
((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", element);

[whimboo]

Once the spec has been updated, Marionette will get that fix via bug 1295538

[mseele]

Any progress going on here? bug 1295538 has been closed as wontfix.
I cannot believe that i need this workaround

WebElement element = driver.findElement(locator);
((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", element);

for firefox and all the other browsers just work out of the box.
