Watch this video to learn how to handle alerts in Selenium.
Alerts in Selenium are pop-up messages that appear on a webpage to provide information or prompt the user for an action. They can be simple alerts with an "OK" button, confirmation alerts with "OK" and "Cancel" options, or prompt alerts that allow users to enter text. In Selenium, you can interact with these alerts using methods like 𝘢𝘤𝘤𝘦𝘱𝘵(), 𝘥𝘪𝘴𝘮𝘪𝘴𝘴(), 𝘨𝘦𝘵𝘛𝘦𝘹𝘵(), and 𝘴𝘦𝘯𝘥𝘒𝘦𝘺𝘴().

Purpose of Alerts:
Alerts are used to capture the user's attention on a webpage, commonly seen in older applications but still used in some modern ones. Examples include JavaScript alert boxes that temporarily block other actions on a webpage.
Interacting with Alerts:
Alerts prevent any other interaction with the page until they are handled. Selenium provides methods to interact with these alerts, such as accept(), dismiss(), getText(), and sendKeys(). These methods allow actions like confirming, canceling, retrieving text, or typing into prompt alerts.
Locating and Triggering Alerts:
Using XPath, the video demonstrates how to locate elements (e.g., a "Click Me" button) that trigger alerts.
After clicking, Selenium can switch to the alert using driver.switchTo().alert() to gain control over it.
Handling Different Alert Types:
For simple alerts, use accept() to close the alert.
For confirmation alerts, use dismiss() to cancel the action or accept() to confirm.
For prompt alerts (those with input fields), use sendKeys() to type input before confirming.
Best Practices with XPath:
The tutorial emphasizes writing efficient XPath expressions for element selection, which is crucial in handling web elements and triggering actions accurately in test scripts.
Exception Handling:
Failure to handle alerts will lead to exceptions. The video demonstrates how to properly capture alert text and handle scenarios to avoid runtime errors.
