----------------------------------
Assignee: sunjincheng
> 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
> Assignee: sunjincheng
>
> 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.
