> org.apache.kafka.streams.integration.RegexSourceIntegrationTest > testRegexMatchesTopicsAWhenDeleted FAILED
>     java.lang.AssertionError: 
>     Expected: <[TEST-TOPIC-A, TEST-TOPIC-B]>
>          but: was <[TEST-TOPIC-A]>
>         at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20)
>         at org.junit.Assert.assertThat(Assert.java:956)
>         at org.junit.Assert.assertThat(Assert.java:923)
>         at org.apache.kafka.streams.integration.RegexSourceIntegrationTest.testRegexMatchesTopicsAWhenDeleted(RegexSourceIntegrationTest.java:211)
> {code}
> I think it is due to the fact that some times the rebalance takes much longer than the specified 60 seconds.
