------------------------------------

             Summary: Convert string-based Table API tests into unit tests
                 Key: FLINK-5269
                 URL: https://issues.apache.org/jira/browse/FLINK-5269
             Project: Flink
          Issue Type: Sub-task
          Components: Table API & SQL
    Affects Versions: 1.2.0
            Reporter: Fabian Hueske


The string-based Table API is currently tested with expensive integration tests. These tests have a huge overlap with the tests of the Scala-expression Table API. Therefore these tests should be converted into unit tests that compare the logical plan constructed by the string-based Table API with the logical plan of an equivalent Scala-expression Table API query.

The logical plan can be retrieved from a {{Table}} as {{Table.logicalPlan}}.
Since the translation from string-based Table API to logical plan does not distinguish between batch and streaming, we do not need separate tests but can remove existing duplicate tests.
