------------------------------------
Summary: Refactor the stream Scala-expression Table API tests
Key: FLINK-5272
URL: https://issues.apache.org/jira/browse/FLINK-5272
Project: Flink
Issue Type: Sub-task
Components: Table API & SQL
Affects Versions: 1.2.0
Reporter: Fabian Hueske
Most tests of the streaming 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 {{DataStreamRel}} nodes) based on the
{{TableTestBase}} class.
In addition we need a few integration tests that check the translation from the
optimized {{DataStreamRel}} plan to a DataStream program. These tests should be
implemented by extending the {{StreamingMultipleProgramsTestBase}} and be
located in few classes to avoid repeated instantiations of the FLink
MiniCluster.
These tests must cover the translation process of each {{DataStreamRel}}
operator.
