利用 Eclipse 進行單元測試

                
import org.jmock.Mock;
import org.jmock.cglib.MockObjectTestCase;
public class ServiceClassTest extends MockObjectTestCase {
	private ServiceClass serviceClass;
	private Mock mockCollaborator;
	private ICollaborator collaborator;
	
	public void setUp(){
		serviceClass = new ServiceClass();
		mockCollaborator = new Mock(ICollaborator.class);
	}
	
	public void testRunServiceAndReturnFalse(){
		mockCollaborator.expects(once()).method\
              ("executeJob").will(returnValue("failure"));
		collaborator = (ICollaborator)mockCollaborator.proxy();
		boolean result = serviceClass.runService(collaborator);
		assertFalse(result);
	}
}
