Three ways of dealing with Alert in automation(Python+Webdriver)

There are 3 ways of dealing with alert in our automation (I don't think there are only 3 ways).

1. The method of selenium:
   driver = webdriver.Chrome()
   driver.get("http://www.baidu.com")
   driver.execute_script("alert(\"hello\")")
   time.sleep(3)
   alert = driver.switch_to_alert()
   alert.accept()
   
   
2. Overwrite the alert of Javascript:
   driver = webdriver.Chrome()
   driver.get("http://www.baidu.com")
   script = "window.alert = function(msg){ return true;}"
   driver.execute_script(script)
   driver.execute_script("alert(\"hello\")")
   
   You will find all alert would not be pop up on this page.
   
   
3. Simulate keystrokes:
   You have to install autopy in your python environment, and the install file at https://pypi.python.org/pypi/autopy/.
   

   driver = webdriver.Chrome()
   driver.get("http://www.baidu.com")
   driver.execute_script("alert(\"hello\")")
   time.sleep(3)
   autopy.key.tap(autopy.key.K_RETURN)
