    97. What is the purpose of switchTo()?


    The switchTo() method in Selenium WebDriver serves the purpose of switching the focus or context of your automation script to a different window, frame, or alert dialog within a web application. It allows you to interact with elements and perform actions in the selected context.

    98. How can you automate API testing in conjunction with Selenium tests?


    Automating API testing in conjunction with Selenium tests is a common practice to ensure comprehensive test coverage of a web application. You can achieve this by integrating API testing frameworks or libraries with your Selenium test automation framework.

    99. What is the significance of WebDriver protocol in Selenium 4?


    The WebDriver protocol plays a significant role in Selenium 4 as it represents a major architectural shift in Selenium’s design. It introduces the W3C WebDriver standard, which is a standardized way of interacting with web browsers, making Selenium more stable, reliable, and compatible across different browsers and WebDriver implementations. 

    100. How does Selenium WebDriver handle file uploads?


    Locate the File Input Element: Use findElement() to locate the file input element by its attributes like id, name, or other unique identifiers.

    Specify the File Path: The file path of the file you wish to upload may be specified using sendKeys(). Give either the file’s absolute or relative path.

    Submit the Form (if necessary): After setting the file path, submit the form or trigger the file upload process on the web page using WebDriver.

    Handle Alerts (if any): If a confirmation alert appears after submitting the form, use WebDriver to handle the alert using methods like switchTo().alert().
