Jenkins runs PHPUnit as follows:
```lang=sh
+ nice -n 19 php /srv/jenkins-workspace/workspace/mediawiki-core-code-coverage/src/tests/phpunit/phpunit.php --exclude-group Dump,Broken,ParserFuzz,Stub --coverage-clover log/clover.xml --coverage-html /srv/jenkins-workspace/workspace/mediawiki-core-code-coverage/cover
```
I imagine the following should suffice to reproduce it:
```lang=sh
mediawiki/tests/phpunit$ php phpunit.php --coverage-html ../coverage
```
