Hello,

We will upgrade the PHPUnit version being used to run tests on the Wikimedia Jenkins.

Bryan Davis proposed a change to upgrade it from 3.7.28 to 3.7.37: https://gerrit.wikimedia.org/r/164683

The new version pass tests on mediawiki/core master and supported release branches so we should be fine.

I will deploy the version bump tomorrow morning (europe) or Oct 16th ~ 8am UTC.

mediawiki/core will be fine but there is a slight change that some extension might complain. I will trigger builds for the most busiest repositories (wikidata, echo, mobilefrontend and so on), but I don't expect any failure.

If something is terribly broken, I will just revert. If there is just a few glitches, I guess developers will need to adjust their code.

cheers,
