Which method allows Selenium to directly authenticate a user through stored cookies?

• A. addStoredCookies()
• B. manageCookies()
• C. addCookie()
• D. setAuthCookies()

Answer: (C)

Selenium provides the capability to manage cookies, which can be used for various purposes, including authentication. The method that allows you to add a specific cookie to the current browser session is the addCookie() method. This method is employed after you've previously stored a cookie, which can be useful for re-authenticating users without manually logging in again.

When you retrieve the stored cookies from a previous session and want to authenticate the user, you can use addCookie() to insert those cookies back into the current session. As a result, the server recognizes the user based on the cookie data, allowing for seamless access without prompting for login credentials again.

Using addCookie() effectively simplifies the testing of authenticated sessions by allowing access to protected resources directly through cookie injection, avoiding the overhead of re-entering user credentials.
