### Question:
DataTypeListItemView implements DataTypeListItem.View { NodeList<Element> getLabels() { return getElement().querySelectorAll(".data-type-label"); } @Inject  DataTypeListItemView(final HTMLDivElement view,
                                final TranslationService translationService,
                                final @DMNEditor ReadOnlyProvider readOnlyProvider); @Override void init(final DataTypeListItem presenter); @Override HTMLElement getElement(); @Override void toggleArrow(final boolean show); @Override void expand(); @Override void collapse(); @Override void showEditButton(); @Override void showSaveButton(); @Override void enableFocusMode(); @Override void disableFocusMode(); @Override boolean isOnFocusMode(); @Override String getName(); @Override void setName(final String name); @Override void showDataTypeNameInput(); @Override void hideDataTypeNameInput(); @Override void setupSelectComponent(final DataTypeSelect typeSelect); @Override void setupConstraintComponent(final DataTypeConstraint dataTypeConstraintComponent); @Override void setupListComponent(final SmallSwitchComponent dataTypeListComponent); @Override void showListContainer(); @Override void hideListContainer(); @Override void showListYesLabel(); @Override void hideListYesLabel(); @Override boolean isCollapsed(); @Override void setDataType(final DataType dataType); static final String UUID_ATTR; static final String NAME_DATA_FIELD; static final String PARENT_UUID_ATTR; }### Answer:
@Test public void testGetLabels() { final Element element1 = mock(Element.class); final Element element2 = mock(Element.class); final HTMLElement viewElement = mock(HTMLElement.class); final NodeList<Element> labels = spy(new NodeList<>()); element1.classList = mock(DOMTokenList.class); element2.classList = mock(DOMTokenList.class); labels.length = 2; doReturn(element1).when(labels).getAt(0); doReturn(element2).when(labels).getAt(0); doReturn(viewElement).when(view).getElement(); when(viewElement.querySelectorAll(".data-type-label")).thenReturn(labels); assertEquals(labels, view.getLabels()); }
