  • Are you sure that the application is launched and navigated to the page where you have the element with id `FavoriteApp_ITEM`? – supputuri Jul 21 '20 at 12:38

  • Meaning, the firefox instance is not launched when you ran the script in EC2? – supputuri Jul 21 '20 at 12:41

This error message...

selenium.common.exceptions.TimeoutException: Message:

...implies that the WebDriver variant was unable to locate the desired WebElement within the timeframe for which the WebDriverWait was constructed.

WebDriverWait

The WebDriverWait constructor takes a WebDriver instance as an argument and timeout in seconds.

Hence, irrespective of usage of either of the expected_conditions, WebDriverWait on failure will result in TimeoutException.

This usecase

In this usecase, the line:

EC.element_to_be_clickable((By.ID, 'FavoriteApp_ITEM'))

was unable to identify the desired element within the desired time frame hence you faced TimeoutException.

However, from TimeoutException it will be tough to dig out the actual result of the failure.

Solution

As a solution to know about the exact cause of the failure, you need to remove the WebDriverWait and replace the line of code with either:

  • find_element_by_class_name(name)
  • find_element_by_css_selector(css_selector)
  • find_element_by_id(id)
  • find_element_by_link_text(link_text)
  • find_element_by_name(name)
  • find_element_by_partial_link_text(partial_link_text)
  • find_element_by_tag_name(tag_name)
  • find_element_by_xpath(xpath)

If required you can slow down the search inducing waits through time.sleep(secs) while debugging.
