Handling UnexpectedAlertPresentException Alerts who hates them? I Do! Who doesn't hate an annoying alert causing your tests / scraping job to fail? I must say they are pretty much on point on the Unexpected part! Fortunately, there are easy ways to mitigate the issue. 1. Disable alerts completely: driver . execute_script( 'window.alert = function(){};' ); execute this script just before where you anticipate the alert and you're golden. 2. You want to see the alert text but not disturb the execution flow. driver . execute_script( 'window.alert = console.info;' ); Now the alerts have been redirected to the console and you don't have to worry about them. (Unless you have to - then you'd have to monitor the console) 3. You know exactly when it comes and want to accept the alert and move on. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 from selenium import webdriver from selenium.webdriver.s
