Example 6 with NoneSingleRel

use of org.apache.calcite.plan.volcano.PlannerTests.NoneSingleRel in project calcite by apache.

the class VolcanoPlannerTest method testRemoveSingleGood.

/**
 * This always worked (in contrast to testRemoveSingleReformed) because it
 * uses a completely-physical pattern (requiring GoodSingleRule to fire
 * first).

@Test
public void testRemoveSingleGood() {
    VolcanoPlanner planner = new VolcanoPlanner();

    planner.addRelTraitDef(ConventionTraitDef.INSTANCE);
