Greg F commented on KAFKA-19828:
--------------------------------
I run the test in a loop in a shell script like this:
#!/bin/bash
set -e
for i in \{1..100}; do
echo ========================================================
echo ======================== $i ============================
echo ========================================================
mvn surefire:test -Dtest=ChainedEmitStrategyTopologyTest3
done
I am attaching output of one such run, where first 5 iterations succeeded, but
the 6th one failed
> Intermittent test failures when using chained emit strategy on window close

> Hi,
> I have a test case that contains a topology with 2 time windows and chained
> emitStrategy calls. The standalone reproduction use case is attached to this
> issue
> The problem is that about 25% of the time the test fails. About 75% of the
> time the test succeeds. I followed the conclusions of

> to make sure that I am sending events at the correct times (at least I think
> my calculations are correct). I really need to get to the bottom of why the
> test fails intermittently, as the test somewhat reflects a real life topology
> of a project I am working on, and we cannot have an intermittently failing
> test in our build pipeline.
