Hello folks,

I’m trying to use springs’ AbstractTransactionalSpringContextTests related with the ddsteps junit extension (www.ddsteps.org). Finally I want to receive the test data for test cases from excel sheets and encase transaction around the test methods (for automatically rollbacks).

I’ve following design problem:
To do this I have to extend the class DDStepsSpringTestCase. This class inherits themselves from AbstractDependencyInjectionSpringContextTests. To use transaction functionally I have to extend the class AbstractTransactionalSpringContextTests too. This is not possible.

My currently solution extends DDStepsSpringTestCase and delegates calls to setUpMethod and tearDownMethod to a member of the type AbstractTransactionalSpringContextTestsWrapper.

This type wraps AbstractTransactionalSpringContextTests and enhanced the visibility of the protected final onSetUp and onTearDown methods of the AbstractTransactionalSpringContextTests class:

public class AbstractTransactionalSpringContextTestsWrapper extends
AbstractTransactionalSpringContextTests
…
public void startTransaction() throws Exception
{
this.onSetUp();
}

public void finishTransaction() throws Exception
{
this.onTearDown();
}

The AbstractTransactionalSpringContextTestsWrapper is used as followed:

public abstract class DDStepsTransactionalSpringContextTests extends DDStepsSpringTestCase implements TransactionalSpringContextTestsCallback
{
AbstractTransactionalSpringContextTestsWrapper transactionalContext = new AbstractTransactionalSpringContextTestsWrapper(thi s);


public final void setUpMethod() throws Exception
{
// delegates the setUp to transactionalContext to start the transaction
transactionalContext.startTransaction();
}
…

Is this the “best” solution or do you have a better idea? Or would you simple copy the functionality of the onSetUp and onTearDown of the AbstractTransactionalSpringContextTests class?
Would this code duplication be ok?

Cheers
Martin
