I just spent quite some time to actually make our tests work with PHPUnit 4 and made travis use phpunit 4. That was a pre-requirement towards having the tests pass on HHVM.

Right now this is failing because hhvm gets OOM killed on travis.
This *might* be caused by hhvm nightly beeing broken (so just trying again next week might work).

With https://gerrit.wikimedia.org/r/167521 merged those problems are gone, Wikibase test run much faster now (also with Zend) and hhvm passes: https://travis-ci.org/mariushoch/mediawiki-extensions-Wikibase/jobs/38448949 (identical to Wikibase master)
