Github user fhueske commented on the issue: https://github.com/apache/flink/pull/2653 I think we should convert the tests for the Java String-based Table API to check the logical plans of queries against the logical plan of a corresponding Scala Expression-based Table API query. That leaves the Scala Table API and SQL tests for batch and streaming. I think some of those can be checked with @twalthr's test framework.
