Mark Miller commented on SOLR-10032:
------------------------------------
It's what I mention above. Surviving 30 runs is an arbitrary initial bar. If
that test has low resource env issues, fails will will pop up over time and
longer beast runs will draw out its true stability.
This will not match Jenkins or everyone local environments, but that is not
really the point either. I promise if a test is truly flakey, I will draw it
out over time. These others tests fail often even in good conditions and short
beasting and will need attention first.
A lot of these tests that pass 30 runs even often will have 1 out of 60 or 1
out of 100 fails or 1 out of 200 fails that can be much more common under
certain conditions.

> We have many Jenkins instances blasting tests, some official, some policeman,
> I and others have or had their own, and the email trail proves the power of
> the Jenkins cluster to find test fails.
> However, I still have a very hard time with some basic questions:
> what tests are flakey right now? which test fails actually affect devs most?
> did I break it? was that test already flakey? is that test still flakey? what
> are our worst tests right now? is that test getting better or worse?
> We really need a way to see exactly what tests are the problem, not because
> of OS or environmental issues, but more basic test quality issues. Which
> tests are flakey and how flakey are they at any point in time.
