Example output:

php vendor/bin/phpunit c:\Users\USER_NAME\Documents\DIR NAME/tests/unit/xxxTest.php --teamcity --colors=never

❌ PHPUnit 10.3.1 by Sebastian Bergmann and contributors.

Test file "c:\Users\USER_NAME\Documents\DIR" not found

Running on Windows 10. I tried to fix the issue myself and issue a PR but got lost in the code :( sorry.

I'm hitting the same issue on Debian.

Looks like the same as #156
