UndoNamespacedNameSingleTokenTest.php
Tests the tokenization of identifier names.
As of PHP 8, identifier names are tokenized differently, depending on them being either fully qualified, partially qualified or relative to the current namespace.
This test file safeguards that in PHPCS 3.x this new form of tokenization is "undone" and the tokenization of these identifier names is the same in all PHP versions based on how these names were tokenized in PHP 5/7.
