Selenium - Wait until element is NOT visible

Question

In the code below, I attempt to wait until an element is visible:

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


        

Answer 1

var wait = new WebDriverWait(Driver.Instance, TimeSpan.FromSeconds(10));
wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("processing")));

The idea is to wait until element is not visible. First line sets wait time that element has to disappear; here it's 10 seconds. Second line uses selenium to check if condition "invisibilityofElementLocated" is met. Element is found by its id as in topic case, that is id="processing". If element doesn't disappear in the requested period of time, a Timeout exception will be raised and the test will fail.
