About backupGlobalsand backupStaticAttributes

By default, PHPUnit runs your tests in a way where changes to global and super-global variables ($GLOBALS, $_ENV, $_POST, $_GET, $_COOKIE, $_SERVER, $_FILES, $_REQUEST) do not affect other tests. Optionally, this isolation can be extended to static attributes of classes.
