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

It is a CapabilityType, so you have to express it in the DesiredCapabilities that you pass when creating the driver. In Python I added this behavior to my FireFox drivers using this code:

        selenium.webdriver.DesiredCapabilities.FIREFOX["unexpectedAlertBehaviour"] = "accept"

I haven't tested this Java but in theory it should work:

DesiredCapabilities cap = new DesiredCapabailities();
cap.setPreference(CapabilityType.UNEXPECTED_ALERT_BEHAVIOUR, 
   org.openqa.selenium.UnexpectedAlertBehaviour.ACCEPT);
WebDriver driver = new FirefoxDriver(cap);
