Unstable code

[dom...@computerlogy.com]

Hi,

Why do I get errors sometimes and other times it works.

My code is simply this:
driver.findElement(By.xpath("//section[@id='objective']/dl/dd/ul/li[2]/p")).click();

Error:
org.openqa.selenium.WebDriverException: unknown error: Element is not clickable at point (557, 395). Other element would receive the click: <div class="page-loading show">...</div>

Dominic, seems to be a timeout issue. have you used wait in your code? if not, use that either implicit or explicit( if needed)

org.openqa.selenium.WebDriverException: unknown error: Element is not clickable at point (557, 395). Other element would receive the click: <div class="page-loading show">...</div>

Yes I use Thread.sleep(3000)

Hi Dominic,

Just increase the wait time little bit more. 

This is generally happens when element not attached with the page and Webdriver try to finds it. 

Thanks,

Nikhil

Error message directly pointing there is page-loading show image on top of other element. So you add explicit wait as below 

public void explicitWaitUntilInvisibilityOfPageLoader() {

try {

WebDriverWait wait = new WebDriverWait(driver, explicitWaitTimeout);

wait.until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("//div[@class='page-loading show']")));

} catch (TimeoutException e) {

Assert.fail("Unable to load Page Loading on Page due in " + explicitWaitTimeout + " sec due to Error : " + e.getMessage());

}

}

Thanks & Regards,

This error is not because element is not attached to DOM.

If element is not attached to DOM completely then you will get StaleElementReferenceException exception.

Yes, Anand you are correct. I was also saying same thing.

"This is generally happens when element not attached with the page and Webdriver try to finds it." (Because page was not loaded completely when webdriver was looking for Element).

Thanks anyways.

Nikhil

Thanks Anand.  Up until now I have just been usuing Thread.sleep (20000)

I recently encountered this error and was able to determine it was caused by a dropdown menu being triggered while attempting to click an item located just below it on the page. This was happening as a result of the screen resolution in use on the test machine, but was also related to the Selenium version. I rolled Selenium back from 2.51.1 to 2.45.0 the issue resolved. I haven't had a chance to follow up to figure out why the newer version is more resolution sensitive.
