All Implemented Interfaces:

junit.framework.Test

public class AggregateClassLoadingTest
extends BaseJDBCTestCase

Test for ensuring the aggregate implementation classes are loaded correctly, even when the context class loader loads Derby engine classes as well. This is a typical situation we have seen with J2EE servers where Derby may be in the application WAR and provided as a system service by the container.
Jira issue DERBY-997
Assumes embedded and only needs to be run in embedded, since all class loading happens on the engine side.

Constructor Detail

AggregateClassLoadingTest

public AggregateClassLoadingTest(java.lang.String name)

Basic constructor.

Method Detail

initializeConnection

protected void initializeConnection(java.sql.Connection conn)
                             throws java.sql.SQLException

Sets the auto commit to false.

Overrides:

initializeConnection in class BaseJDBCTestCase

Parameters:

conn - Connection to be intialized

Throws:

java.sql.SQLException - Error setting the initial state.

suite

public static junit.framework.Test suite()

Returns the implemented tests.

Returns:

An instance of Test with the implemented tests to run.

testAggregateMAX

public void testAggregateMAX()
                      throws java.sql.SQLException

Throws:

java.sql.SQLException

testAggregateMIN

public void testAggregateMIN()
                      throws java.sql.SQLException

Throws:

java.sql.SQLException

testAggregateAVG

public void testAggregateAVG()
                      throws java.sql.SQLException

Throws:

java.sql.SQLException

testAggregateCOUNT

public void testAggregateCOUNT()
                        throws java.sql.SQLException

Throws:

java.sql.SQLException

testAggregateCOUNT2

public void testAggregateCOUNT2()
                         throws java.sql.SQLException

Throws:

java.sql.SQLException

testAggregate

private void testAggregate(java.lang.String query)
                    throws java.sql.SQLException

Just run and display the aggregates result. Test some aggregates, their generated class will attempt to load the internal aggregate through the context loader first, and then any remaining loader.

Throws:

java.sql.SQLException
