> 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.
