Example run: https://travis-ci.org/piwik/piwik/builds/78185419
Instead of having 1 job that takes about 35-45 minutes we now have 2 jobs that take about 17-24minutes each. As mentioned in the issue we could also split it into three jobs but then other commits take longer to start maybe as we need more jobs. We can see how it goes and still change things later.
Not sure if we can close #8222 afterwards for now? I'd close I think as goal of
the UI tests should run ideally in less than 20 or 25 minutes is satisfied. They are even faster then
this is a great win, what a good idea!
Re: Builds artifacts does it work smoothly when the build is split across 2 jobs (ie. can we still see all screenshots diffs in one page on builds-artifacts)
this will close #8222 beautifully for sure
I tried it with a failure in first run and with a failure in second run and worked. Haven't tested with an error in both builds but so far screenshots are always added to that directory on builds-artifacts I think so it should work
Actually, I noticed files get deleted every time we upload new artifacts. This was changed recently in https://github.com/piwik/ui-tests-viewer/commit/a0b03de6f9257393c9a511723c661ebeb14795c1 and will maybe simply undo that delete directory to fix it for now
