-How to Simulate HTTP Authentication in a Functional Test
-========================================================
-
-.. caution::
-
-    Starting from Symfony 5.1, a ``loginUser()`` method was introduced to
-    ease testing secured applications. See :ref:`testing_logging_in_users`
-    for more information about this.
-
-    If you are still using an older version of Symfony, view
-    `previous versions of this article`_ for information on how to simulate
-    HTTP authentication.
