### Question:
DMNClientServicesProxyImpl implements DMNClientServicesProxy { @Override public void loadNodesFromImports(final List<DMNIncludedModel> includedModels, final ServiceCallback<List<DMNIncludedNode>> callback) { kogitoImportsHelper.loadNodesFromModels(includedModels, callback); } @Inject  DMNClientServicesProxyImpl(final TimeZonesProvider timeZonesProvider,
                                      final DMNMarshallerImportsClientHelper kogitoImportsHelper); @Override void loadModels(final Path path,
                           final ServiceCallback<List<IncludedModel>> callback); @Override void loadNodesFromImports(final List<DMNIncludedModel> includedModels,
                                     final ServiceCallback<List<DMNIncludedNode>> callback); @Override void loadPMMLDocumentsFromImports(final Path path,
                                             final List<PMMLIncludedModel> includedModels,
                                             final ServiceCallback<List<PMMLDocumentMetadata>> callback); @Override void loadItemDefinitionsByNamespace(final String modelName,
                                               final String namespace,
                                               final ServiceCallback<List<ItemDefinition>> callback); @Override void parseFEELList(final String source,
                              final ServiceCallback<List<String>> callback); @Override void parseRangeValue(final String source,
                                final ServiceCallback<RangeValue> callback); @Override void isValidVariableName(final String source,
                                    final ServiceCallback<Boolean> callback); @Override void getTimeZones(final ServiceCallback<List<DMNSimpleTimeZone>> callback); @Override void loadDataObjects(final ServiceCallback<List<DataObject>> callback);  }### Answer:
@Test public void testLoadNodesFromImports() { final List<DMNIncludedModel> includedModels = Collections.emptyList(); final ServiceCallback<List<DMNIncludedNode>> callback = newServiceCallback(actual -> assertThat(actual).isEmpty()); service.loadNodesFromImports(includedModels, callback); }
