Armin Braun commented on KAFKA-4859:
------------------------------------
[~guozhang] so basically this can just be resolved by setting a higher timeout
on the waiting before the last assert at the end of the test.
{code:java}
final List<KeyValue<String, Long>> actualClicksPerRegion =
IntegrationTestUtils.waitUntilMinKeyValueRecordsReceived(consumerConfig,
outputTopic, expectedClicksPerRegion.size(), 2 *
IntegrationTestUtils.DEFAULT_TIMEOUT);
assertThat(actualClicksPerRegion, equalTo(expectedClicksPerRegion));
}
{code}
Tested this over 200+ iterations just now, while I get to less than 30 without
this adjustment.
What I find interesting though is that the runtime for this test is always very
close to 30s. Always kind of between 30.4s - 30.6s. Is this just a coincidence
or is that 30s maybe coming from some place I missed and would allow expressing
the timeout a little cleaner (i.e. as some constant + x)?
If not I'd just put in a PR with the raised timeout?
