### Question:
TimeSelectorView implements TimeSelector.View { @EventHandler("time-input") public void onTimeInputBlur(final BlurEvent blurEvent) { onBlur(blurEvent); } @Inject  TimeSelectorView(final HTMLInputElement timeInput,
                            final TimePicker picker,
                            final TimeZoneProvider timeZoneProvider,
                            final TimeValueFormatter formatter,
                            final @Named("i") HTMLElement toggleTimeZoneIcon,
                            final HTMLButtonElement toggleTimeZoneButton,
                            final ClientTranslationService translationService,
                            final HTMLSelectElement timeZoneSelector,
                            final HTMLOptionElement typeSelectOption); void onSelectChange(final JQuerySelectPickerEvent event); @Override String getValue(); @Override void setValue(final String value); @Override void setPlaceholder(final String placeholder); @Override void setOnInputChangeCallback(final Consumer<Event> onValueChanged); @Override void select(); @Override void setOnInputBlurCallback(final Consumer<BlurEvent> onValueInputBlur); @EventHandler("time-input") void onTimeInputBlur(final BlurEvent blurEvent); @EventHandler("toggle-timezone-button") void onToggleTimeZoneButtonClick(final ClickEvent clickEvent); @Override boolean isChildOfView(final Object element); @Override void init(final TimeSelectorView presenter);  }### Answer:
@Test public void testOnTimeInputBlur() { final BlurEvent event = mock(BlurEvent.class); final Element target = mock(Element.class); doReturn(target).when(view).getEventTarget(event); doReturn(false).when(view).isChildOfView(target); view.onTimeInputBlur(event); verify(onValueInputBlur).accept(event); }
