[jira] [Created] (FLINK-5270) Refactor the batch Scala-expression Table API tests

Fabian Hueske created FLINK-5270:
------------------------------------

             Summary: Refactor the batch Scala-expression Table API tests
                 Key: FLINK-5270
                 URL: https://issues.apache.org/jira/browse/FLINK-5270
             Project: Flink
          Issue Type: Sub-task
          Components: Table API & SQL
    Affects Versions: 1.2.0
            Reporter: Fabian Hueske


Most tests of the batch Scala Table API tests are full-blown integration tests which are rather expensive to execute.

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

In addition we need a few integration tests that check the translation from the optimized {{DataSetRel}} plan to a DataSet program. These tests should be done by extending the {{TableProgramsCollectionTestBase}} (see FLINK-5268). These tests must cover the translation process of each {{DataSetRel}} operator.
