Stefania commented on CASSANDRA-12784:
--------------------------------------
Thanks for the review.
The multiplexed run returned a number of
[failures|https://cassci.datastax.com/view/Dev/view/stef1927/job/stef1927-testall-multiplex/26/]
in {{RandomReplicationAwareTokenAllocatorTest.testExistingCluster}}, is this
test also expected to be flaky or is this a problem?
Splitting the test caused a failure in testall, I've fixed it and relaunched.
bq. The stack printout for single flakes could be useful to track the history
of a failure; I would prefer not to lose it, but I wouldn't stop the commit if
that is something you think is worth sacrificing.
The stack printout still there, the logger is smart enough to work it out, I've
tested it locally, see sample output below.
bq. I would rename flakyTestNewCluster in the base class to just testNewCluster
since the individual runner is the one that declares it flaky and handles that.
Done.
bq. Is there a reason to post the the commits view instead of the the branch
one? There's no direct way to get from the commits view to compare which is the
one most useful for reviews.
Not really:
