Looks like it doesn't work with PHPUnit versions < 10.
I had the same issue with 9.6.11, but after upgrading to PHPUnit 10.4, evrything works like expected.

Thanks for the report! This package uses the event system that is new in PHPUnit v10, so I don't support older versions.

#4 makes this more explicit when requiring the package.
