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

             Summary: PlannerTest ignores top-level order by clause (~RootRel.collation)
                 Key: CALCITE-2768
                 URL: https://issues.apache.org/jira/browse/CALCITE-2768
             Project: Calcite
          Issue Type: Test
          Components: core
    Affects Versions: 1.18.0
            Reporter: Vladimir Sitnikov
            Assignee: Vladimir Sitnikov


{code:java}    RelTraitSet traitSet = planner.getEmptyTraitSet()
        .replace(EnumerableConvention.INSTANCE);
{code}
should be replaced with
{code:java}    RelTraitSet traitSet = convert.getTraitSet()
        .replace(EnumerableConvention.INSTANCE);
{code}

Otherwise PlannerTest asks Planner to produce "empty collation" even in case Root relation has order by.
