Github user mbalassi commented on the pull request: https://github.com/apache/flink/pull/789#issuecomment-109218281 Both are good points. As for the socket test I can do one of the following: * Do not test it * Test it with smaller data * Mock the socket with some collection I am not not really happy with any of these options to be honest, but maybe I am just missing something. As for the ITCases, you are right, I have to admit that I was looking at the [AvroOutputFormatTest](https://github.com/apache/flink/blob/master/flink-staging/flink-avro/src/test/java/org/apache/flink/api/avro/AvroOutputFormatTest.java) and named my tests accordingly. So you would suggest renaming that too then?
