Class DialectTest

java.lang.Object

junit.framework.Assert

junit.framework.TestCase

mondrian.test.DialectTest

All Implemented Interfaces:

junit.framework.Test

public class DialectTest
extends junit.framework.TestCase

Unit test which checks that Dialect accurately represents the capabilities of the underlying database.

The existing mondrian tests, when run on various databases and drivers, make sure that Dialect never over-states the capabilities of a particular database. But sometimes they under-state a database's capabilities: for example, MySQL version 3 did not allow subqueries in the FROM clause, but version 4 does. This test helps ensure that mondrian is using the full capabilities of each database.

NOTE: If you see failures in this test, let the mondrian developers know! You may be running a version of a database which no one has tried before, and which has more capabilities than we expect. If you tell us about them, we can change mondrian to use those features.
