------------------------------------
Summary: Refactor the batch SQL tests
Key: FLINK-5271
URL: https://issues.apache.org/jira/browse/FLINK-5271
Project: Flink
Issue Type: Sub-task
Components: Table API & SQL
Affects Versions: 1.2.0
Reporter: Fabian Hueske
Most tests of the batch 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 {{DataSetRel}} nodes) based on the
{{TableTestBase}} class.
Since the translation from {{DataSetRel}} nodes to the DataSet programs is
covered by the batch Table API SQL tests (see FLINK-5270), we do not need
additional integration tests that validate the result of an execution (except
for the case where a certain DataSetRel node cannot be constructed via the
Table API.).
