In 2.2 many tests fail (in compare to 2.1)
trafficstars
When make runtests is run under user many tests fail in 2.2 in compare to 2.1 where no tests fail.
Tests are much more useful (especially for distributions) when they should pass or skipped. In that case it's easy to add test run into CI and detect regressions early.
