testing controls

[Christopher Snow]

I have a control (ControlA) that has a reference to another control (ControlB). 
I would like to test ControlA using a mock of ControlB.  I have created a
setting to set ControlA's reference to ControlB from the test case.  However to
do this, I need to put the setter in the business interface.  Is there a better
way?

Thanks in advance ...


@ControlImplementation
public class ControlAImpl ... {

   @Control
   private ControlB controlB;

   public void setControlB( ControlB control ) {
      controlB = control
   }

   // business logic
}

@ControlInterface
public interface ControlA ...{
    // bad idea? non business method in business interface
    public void setControlB( ControlB control );
}


public class ControlAImplTest extends ControlTestCase {

   @Control
   private ControlA controlA;

   public void testX() {
      ControlB mockControlB = // create mock of ControlB
      controlA.setControlB( mockControlB )

      // test business logic here
   }
}
