This Prompt Alert asks some input from the user and selenium webdriver can enter the text using sendkeys(" input…. ").

3) Confirmation Alert.

How to handle Alert in Selenium WebDriver

Alert interface provides the below few methods which are widely used in Selenium Webdriver.

1) void dismiss() // To click on the 'Cancel' button of the alert.

driver.switchTo().alert().dismiss();

2) void accept() // To click on the 'OK' button of the alert.
driver.switchTo().alert().accept();

3) String getText() // To capture the alert message.

We can easily switch to alert from the main window by using Selenium's .switchTo() method.
