How to handle an Alert with “UnexpectedAlertBehaviour” capability in Selenium?

Question

In selenium framework 2.25, I see that we have the UnexpectedAlertBehaviour enum type, but I don\'t know how to use it.

Answer 1

To manage any of the errors you can got, you only have to put into a try/block using the Exception NAMEERROR like this:

from selenium.common.exceptions import UnexpectedAlertBehaviour
from selenium.common.exceptions import UnexpectedAlertPresentException
try:
  var = driver.some_function()
  return True
except UnexpectedAlertBehaviour:
  print "We have raised the UnexpectedAlertBehaviour"
  return False
except UnexpectedAlertPresentException:
  print "UnexpectedAlertPresentException"
  return False

I know this code is not in Java, but the basis is the same. Try/Catch with name of exception. You can see an example of this on my post of the alerts() handling here
