public abstract class SqlToRelTestBase
extends TestCase

SqlToRelTestBase is an abstract base for tests which involve conversion from SQL to relational algebra.

SQL statements to be translated can use the schema defined in MockCatalogReader; note that this is slightly different from Farrago's SALES schema. If you get a parser or validator error from your test SQL, look down in the stack until you see "Caused by", which will usually tell you the real error.

createTester

protected SqlToRelTestBase.Tester createTester()

getDiffRepos

protected DiffRepository getDiffRepos()

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.

Returns:

Diff repository
