This is due to the PHPUnit version used.
We are using the TravisCI default, which is PHPUnit 4.x. I recall Sebastian saying he fixed HHVM compat, so I'm not sure what the issue there is. Will investigate.

Jeroen, any updates?
Core uses PHPUnit too, and its unit tests are passing with Travis CI under HHVM.
I think this was fixed?
Sorry not true: https://travis-ci.org/wmde/Diff/jobs/38707716
Probably needs a change like in https://github.com/wmde/WikibaseDataModel/commit/3dd5504a1a6568e6a8d237184ee578c3352cfc61
Unless there are breaking changes we made for HHVM support, I suggest be backport the changes onto the 1.x branch and do a 1.1.0 release rather than already releasing 2.0. I do not think a breaking release otherwise justifies the hassle it causes.
