Expected behavior

can run.

[wol-soft]

I've also encountered the error (Runtime PHP 8.2.5). Downgrading to 10.1.1 and the tests run again.

[hafiz-abdul-moid]

I've also encountered the error (Runtime PHP 8.18).

Same issue with PHP 8.1.18

It appears that you have different installations of PHPUnit mixed up.

For instance, you may have used Composer to install PHPUnit and have configured the autoloader generated by Composer as PHPUnit's bootstrap script but then you invoke PHPUnit using an executable other than vendor/bin/phpunit.

Downgrading helped me too. I used composer
