Hi all, In a couple of minutes I've made some (not complicated) fixes to make Rubric tests green again: https://github.com/pharo-project/pharo/pull/3129 This is of course not a super Rubric enhancement (for which I've opened another issue requesting some missing feature https://github.com/pharo-project/pharo/issues/3128) but this allows us to move on with a better infrastructure :). There are still some some tests that fail from time to time, related to system announcers and finalization. See https://github.com/pharo-project/pharo/issues/2471. Though I've spent half a day yesterday and half today trying to track it down, I don't yet have a clear way of reproducing it. I've read the entire code that touches this part of the system and I really bet this is a race condition :). So any second pair of eyes here would really be helpful! Guille
