[xabbuh]

The test suite would fail like this without the changes in the PHPUnitExtension:

PHPUnit 11.5.6 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.2.27
Configuration: /home/runner/work/doctrine-test-bundle/doctrine-test-bundle/tests/phpunit.xml

........................SSI....

Time: 00:00.060, Memory: 26.00 MB
