For MediaWiki core, the PHP code coverage is done twice per day because it takes two hours to generate ( build time trend).

Timo talked about potentially generating coverage for the JavaScript as well but I am unsure whether anything started.

Regardless, 2 hours is way too long and I am tempted to decline this task in our current state. It is potentially solvable though, a few ideas:

• actually spend time speeding up PHP tests
• figure out how to get coverage with HHVM and potentially up PHPUnit (we use Zend / xdebug / PHPUnit 3.x).
• split true unit tests and the integration tests

Which is essentially what I said on the parent task T100294#1322186 :-D

yeah, sorry, this might be a straight dupe of that one, the tasks relating to this topic are a bit over-lapping...

Creating a task is cheap so there is no problem in abusing the create button :-]
