var wait = new WebDriverWait(Driver.Instance, TimeSpan.FromSeconds(10));
wait.Until(ExpectedCon         


        

Answer 1

Yes, you can create your own ExpectedCondition, just revert visible to not visible.

Here is how to do it in python:

from selenium.webdriver.support.expected_conditions import _element_if_visible

class invisibility_of(object):

    def __init__(self, element):
        self.element = element

    def __call__(self, ignored):
        return not _element_if_visible(self.element)

and how to use it:

wait = WebDriverWait(browser, 10)
wait.until(invisibility_of(elem))
