Add AlertAuthenticateUsingUserAndPassword(user, password)

[lewijw]

Does anyone have a problem with this change? Note there are some special circumstances. First, the Selenium method is declared @beta. See:

https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/Alert.html

Second, I have a test that is working with the new method, but it only works if I use the explorer driver. Any advice or information on why that might be or what I might do to resolve this is appreciated. Details: with the chrome or firefox drivers, Selenium is having problems finding the alert even though it is clearly appearing. The timeout is occurring. I set it to 10 seconds. I am also making sure I set the browserID after the timeout.

I know that there are 3 kinds of Alert provided by HTML DOM, "alert", "confirm" and "prompt". Please refer to https://www.w3schools.com/js/js_popup.asp. They are supported by Selenium API, we have regression test running with them every day, please refer to DriverMiscCommandTests.testAPI_Misc_Alert().

We need to know what type of alert is being tested and if it is supported by Selenium. Maybe Some javascript window looks like an Alert, but it is not considered as an Alert by Selenium.
If it is supported by IE as you said, then we might need to check the version of chromedriver.exe and selenium-driver-standalone.xxx.jar to get it supported in chrome or firefox.
