> Key: KAFKA-21193
> URL: https://issues.apache.org/jira/browse/KAFKA-21193
> Project: Kafka
> Issue Type: Test
> Components: streams, unit tests
> Reporter: 이선민

>
> SuppressionIntegrationTest takes about 290 seconds locally. 6 of its 14
> cases take 42 to 46 seconds each, while the others take about 2 seconds.
> Each test method uses a fixed application id, so the withHeaders=false and
> withHeaders=true runs share one consumer group. The stream thread does not
> leave the group on close, so the second run waits until the previous
> member's session times out (45s).
> shouldUseDefaultSerdes also reuses the "-shouldInheritSerdes" test id, so
> it shares the group and topics with shouldInheritSerdes and its first run
> waits as well.
> The two shouldShutdownWhen... tests are not affected, because their members
> send a LeaveGroup when the stream thread fails.
> We can isolate each run with safeUniqueTestName(testInfo), as KAFKA-21133
> did for FineGrainedAutoResetIntegrationTest.
> JoinStoreIntegrationTest has the same issue: each of its two parameterized
> tests reuses an application id across invocations, causing the second
> invocation to wait for the previous member's session timeout. Include
> both tests in the same fix by giving each invocation a unique application id.
