### Question:
ElementBinding implements Binding { @Override public void updateFromPmo() { try { aspectUpdaters.updateUI(); componentWrapper.postUpdate(); } catch (RuntimeException e) { throw new LinkkiBindingException( "Error while updating UI (" + e.getMessage() + ") in " + toString(), e); } } ElementBinding(ComponentWrapper componentWrapper, PropertyDispatcher propertyDispatcher,
            Handler modelChanged, List<LinkkiAspectDefinition> aspectDefinitions); PropertyDispatcher getPropertyDispatcher(); @Override void updateFromPmo(); @Override Object getBoundComponent(); @Override @SuppressFBWarnings(value = "NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE", justification = "because that's what requireNonNull is for") Object getPmo(); @Override MessageList displayMessages(MessageList messages); @Override String toString();  }### Answer:
@Test public void testUpdateFromPmo_updateAspect() { Handler componentUpdater = mock(Handler.class); LinkkiAspectDefinition aspectDefinition = mock(LinkkiAspectDefinition.class); when(aspectDefinition.supports(any())).thenReturn(true); when(aspectDefinition.createUiUpdater(any(), any())).thenReturn(componentUpdater); ElementBinding fieldBinding = new ElementBinding(new TestComponentWrapper(field), propertyDispatcherValue, Handler.NOP_HANDLER, Arrays.asList(aspectDefinition)); fieldBinding.updateFromPmo(); verify(componentUpdater).apply(); }
