-------------------------------

             Summary: Port DecimalITCase to unit tests
                 Key: FLINK-13382
                 URL: https://issues.apache.org/jira/browse/FLINK-13382
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Planner
            Reporter: Jark Wu
             Fix For: 1.10.0


There are 81 query tests in {{org.apache.flink.table.runtime.batch.sql.DecimalITCase}} and 67 query tests in {{org.apache.flink.table.runtime.batch.table.DecimalITCase}}.

Note that each query will be executed on a MiniCluster which will consume a lot of testing time. However, decimals can be tested as unit tests similar to other Scalar functions tests.

So I would suggest to move Decimal IT cases to unit tests {{org.apache.flink.table.expressions.DecimalTypeTest}}. This should save much testing time.

In the meanwhile, IMO, this is not required by 1.9 release.
