------------------------------------
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.
