Selenium Interview Question 11 – Which Class Implements Alert Interface in Selenium WebDriver?

As a part of Selenium Interview Questions series, in this post, we will see about Implement class of Alert interface.

Someone asked me this question and I felt this is good to share with others as well. So here is the post for the same.

Honestly, I was also not aware of this. So I started researching.

First I went to Alert interface Javadoc. I did not find any implemented class information there.

Then I looked at RemoteWebDriver Javadoc as it is concrete immediate class of WebDriver interface. There I got my answer.

There is an inner class named “RemoteAlert ” which implements Alert interface and define methods declared in Alert interface as shown above.

When we use switchTo().alert() method, it returns a reference of RemoteAlert class which is up cast to Alert interface.
