public class HepPlannerTest
extends RelOptTestBase

HepPlannerTest is a unit test for HepPlanner. See RelOptRulesTest for an explanation of how to add tests; the tests in this class are targeted at exercising the planner, and use specific rules for convenience only, whereas the tests in that class are targeted at exercising specific rules, and use the planner for convenience only. Hence the split.

Method Detail

getDiffRepos

protected DiffRepository getDiffRepos()

Description copied from class: SqlToRelTestBase

Returns the default diff repository for this test, or null if there is no repository.

The default implementation returns null.

Sub-classes that want to use a diff repository can override. Sub-sub-classes can override again, inheriting test cases and overriding selected test results.

And individual test cases can override by providing a different tester object.

Overrides:

getDiffRepos in class SqlToRelTestBase

Returns:

Diff repository
