### Question:
DataTypeListItemView implements DataTypeListItem.View { void setupRowMetadata(final DataType dataType) { getDragAndDropElement().setAttribute(UUID_ATTR, dataType.getUUID()); getDragAndDropElement().setAttribute(PARENT_UUID_ATTR, dataType.getParentUUID()); setupRowCSSClass(dataType); } @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 testSetupRowMetadata() { final DataType dataType = mock(DataType.class); final DOMTokenList classList = mock(DOMTokenList.class); when(dataType.getUUID()).thenReturn("1234"); when(dataType.getParentUUID()).thenReturn("4567"); dragAndDropElement.classList = classList; view.setupRowMetadata(dataType); verify(dragAndDropElement).setAttribute(UUID_ATTR, "1234"); verify(dragAndDropElement).setAttribute(PARENT_UUID_ATTR, "4567"); verify(view).setupRowCSSClass(dataType); }
