BaseDTDOMElement extends BaseDOMElement<T, W> { @Override protected void setupDelegatingMouseMoveHandler() { } BaseDTDOMElement(final W widget,
                            final GridLayer gridLayer,
                            final GridWidget gridWidget);   }### Answer:
@Test @SuppressWarnings("unchecked") public void setupDelegatingMouseMoveHandlerDoesNotAttachHandler() { element.setupDelegatingMouseMoveHandler(); verify(widgetContainer, never()).addDomHandler(any(EventHandler.class), any(DomEvent.Type.class)); }
