### Question:
DataTypeSearchBarView implements DataTypeSearchBar.View { void refreshSearchBarState() { final boolean isActive = !isEmpty(searchBar.value); searchBarActive(isActive); } @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 testRefreshSearchBarStateWhenItsActive() { searchBar.value = "keyword"; view.refreshSearchBarState(); verify(searchIcon.classList).add(HIDDEN_CSS_CLASS); verify(closeSearch.classList).remove(HIDDEN_CSS_CLASS); }
@Test public void testRefreshSearchBarStateWhenItsNotActive() { searchBar.value = ""; view.refreshSearchBarState(); verify(searchIcon.classList).remove(HIDDEN_CSS_CLASS); verify(closeSearch.classList).add(HIDDEN_CSS_CLASS); }
