Run code coverage without a phpunit.xml about phpunit

I do not think that this would be useful, sorry.

The --coverage-filter CLI option exists for this purpose. Are you saying that it does not work or that you did not know about it? ;-)

I did not know about this option - thank you.

Also I wondern, when I run only a subset of the test-suite (which I do because I pass concret paths to tests to phpunit), whether it could just create coverage for these tests involved, without asking me to repeat a coverage filter (I already told with --coverage-html=coverage that I wan't coverage). might be helpful from a DX point of view.

One has nothing to do with the other.

Closing this as the problem was already solved (--coverage-filter exists).

I totally agree. let me re-phrase the idea from a end-user perspective.

I run vendor/bin/phpunit tests/library/UrlHelperTest.php --coverage-text because I want to run this particular test and want a coverage report which code was executed because of this test.

since UrlHelperTest.php declares CoversClass via metadata, I think PHPUnit "could find" via the metadata which classes it needs to generate coverage for, without me additionally adding a filter...?
