How can Selenium WebDriver be used to detect broken links?

1.	How can Selenium WebDriver be used to detect broken links?
Answer» You might be asked this tricky question by the interviewer. As an example, he could give you a web page with 20 links, and you would have to determine which of those 20 links are working and which aren't or are broken. Considering that you must verify the functionality of each link, the workaround is to send HTTP requests to each link and analyze the response. When you navigate to a URL using the driver.get() method, you will receive a 200 - OK status response. It is evident that the link has been obtained and is working. In the case of any other status, the link is broken. Let’s now understand how to do that. As a first step, we must determine the different hyperlinks on the webpage using anchor tags. We can obtain hyperlinks for each tag using the attribute 'href' value and analyze the response received using the driver.get() method.
