### Question:
DataTypeSearchBarView implements DataTypeSearchBar.View { @EventHandler("search-bar") public void onSearchBarKeyUpEvent(final KeyUpEvent event) { if (isEscape(event)) { presenter.reset(); } else { search(); } } @Inject  DataTypeSearchBarView(final HTMLInputElement searchBar,
                                 final @Named("span") HTMLElement searchIcon,
                                 final HTMLButtonElement closeSearch,
                                 final TranslationService translationService); @PostConstruct void setupSearchBar(); @Override void init(final DataTypeSearchBar presenter); @EventHandler("close-search") void onSearchBarCloseButton(final ClickEvent e); @EventHandler("search-bar") void onSearchBarKeyUpEvent(final KeyUpEvent event); @EventHandler("search-bar") void onSearchBarKeyDownEvent(final KeyDownEvent e); @EventHandler("search-bar") void onSearchBarChangeEvent(final ChangeEvent e); @Override void resetSearchBar(); @Override void showSearchResults(final List<DataType> results); void refreshItemsPosition();  }### Answer:
@Test public void testOnSearchBarKeyUpEventWhenKeyPressedIsEscape() { final KeyUpEvent event = mock(KeyUpEvent.class); when(event.getNativeKeyCode()).thenReturn(KeyCodes.KEY_ESCAPE); view.onSearchBarKeyUpEvent(event); verify(presenter).reset(); }
