I just saw the release of phpunit 12.3 which introduces this change.
It may produce the same kind of error as in #67, fixed by two times in #68 and #139.
It may require to update the regex again and check against phpunit version to handle the name and dataset properly.
I created the issue only for reference if someone encounters the issue. I won't be able to try and fix this until the end of the year unfortunately.
PR welcome or reproducer is welcome if the issue appears. 🙂
