Log File of Flink Unit Test
Hi, I am trying to understand a Flink Unit Test case and so was checking
the logs of it on my local machine. But I could not find the log file.
Could anyone tell me where/how to get the logs for the unit test case?
In Hadoop, under surefire-reports, the log, out and err file of test class
will be present.
mvn -Dtest="StreamGraphGeneratorTest" -DfailIfNoTests=false test
Thanks,
Prabhu Joseph

It prints below INFO logs but not the logs that are part of flink classes.

You can try to modify resources/log4j2-test.properties.
`rootLogger.level = OFF` => `rootLogger.level = INFO`
