             Summary: Refactor verifyPlan method in TableTestBase
                 Key: FLINK-20509
                 URL: https://issues.apache.org/jira/browse/FLINK-20509
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Planner
            Reporter: godfrey he


 Currently, we use {{verifyPlan}} method to verify the plan result for both {{RelNode}} plan and {{ExecNode}} plan, because their instances are the same. But once the implementation of {{RelNode}} and {{ExecNode}} are separated we can't get {{ESTIMATED_COST}} and {{CHANGELOG_MODE}} on {{ExecNode}} plan. So in order to make the methods more clear, the {{verifyPlan}} method can be separated into two methods, {{verifyRelPlan}} for verifying the {{RelNode}} plan, and {{verifyExecPlan}} for verifying the {{ExecNode}} plan.
