=============================================
Rule ``php_unit_set_up_tear_down_visibility``
=============================================

Changes the visibility of the ``setUp()`` and ``tearDown()`` functions of
PHPUnit to ``protected``, to match the PHPUnit TestCase.

.. warning:: Using this rule is risky.

   This fixer may change functions named ``setUp()`` or ``tearDown()`` outside
   of PHPUnit tests, when a class is wrongly seen as a PHPUnit test.
