### Question:
Xsd2UmlPluginHostAdapter implements Xsd2UmlPluginHost, Xsd2UmlHostedPlugin { @Override public List<TaggedValue> tagsFromAppInfo(final XmlSchemaAppInfo appInfo, final Xsd2UmlPluginHost host) { return Collections.emptyList(); } Xsd2UmlPluginHostAdapter(final ModelIndex mapper); @Override Xsd2UmlHostedPlugin getPlugin(); @Override Collection<TagDefinition> declareTagDefinitions(final Xsd2UmlPluginHost host); @Override Identifier ensureTagDefinitionId(final String name); @Override String getAssociationEndTypeName(final ClassType classType, final Attribute attribute,
            final Xsd2UmlPluginHost host); @Override TagDefinition getTagDefinition(final Identifier id); @Override Type getType(final Identifier typeId); @Override boolean isAssociationEnd(final ClassType classType, final Attribute attribute, final Xsd2UmlPluginHost host); @Override String nameAssociation(final AssociationEnd lhs, final AssociationEnd rhs, final Xsd2UmlHostedPlugin host); @Override String nameFromComplexTypeExtension(final QName complexType, final QName base); @Override String nameFromSchemaElementName(final QName name); @Override String nameFromSchemaAttributeName(final QName name); @Override String nameFromSimpleTypeRestriction(final QName simpleType, final QName base); @Override String nameFromSchemaTypeName(final QName name); @Override List<TaggedValue> tagsFromAppInfo(final XmlSchemaAppInfo appInfo, final Xsd2UmlPluginHost host);  }### Answer:
@Test public void testTagsFromAppInfo() throws Exception { Assert.assertEquals(Collections.emptyList(), adapter.tagsFromAppInfo(new XmlSchemaAppInfo(), host)); }
