             Summary: Refactor stream SQL tests
                 Key: FLINK-5273
                 URL: https://issues.apache.org/jira/browse/FLINK-5273
             Project: Flink
          Issue Type: Sub-task
          Components: Table API & SQL
    Affects Versions: 1.2.0
            Reporter: Fabian Hueske


Most tests of the streaming SQL tests are full-blown integration tests which are rather expensive to execute.

All tests should be converted into unit tests that validate the resulting execution plan (consisting of {{DataStreamRel}} nodes) based on the {{TableTestBase}} class.

Since the translation from {{DataStreamRel}} nodes to the DataStream programs is covered by the stream Table API tests (see FLINK-5272), we do not need additional integration tests that validate the result of an execution (except for the case where a certain DataStreamRel node cannot be constructed via the Table API.).
