I was wondering if we could run a large regression test set (about 600000 test cases that run for approx. 30 Minutes) in parallel to other tests.

Currently, the tests are deactivated with the stub annotation

https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Math/+/860981/1/tests/phpunit/unit/TexVC/EnWikiFormulaeTest.php#16

or the skip command

respectively. I was looking at the integration-config repository, and did not really understand how I could add custom test config here.
