🤞 that builds run through (or at least pass installation)

OK, but incomplete, skipped, or risky tests!
Tests: 5805, Assertions: 10751, Skipped: 65, Incomplete: 1.

Just now realized that #3229 should have solved that already, but did not end up in the 7.0 branch. So we actually need to backport that It did end up in 7.0, just the composer merger overwrote the collection phpunit version

@albe thanks for taking care

Yep, I realized that yesterday as well: https://neos-project.slack.com/archives/C12EZDXA8/p1607365582260300

Fixed that by merging back and forth…

Yeah. All is well with this now (and #3232 will prevent the composer merger from overwriting this again). Tests also green :)

Ah, then I misunderstood what you meant! The merge of the PR related to PhpUnit was fine, there was nothing to fix… the dependency was broken "afterwards in secrecy" by the branching…
