### Question:
DMNClientServicesProxyImpl implements DMNClientServicesProxy { @Override public void parseFEELList(final String source, final ServiceCallback<List<String>> callback) { parserService.call(onSuccess(callback), onError(callback)).parseFEELList(source); } @Inject  DMNClientServicesProxyImpl(final WorkspaceProjectContext projectContext,
                                      final Caller<DMNIncludedModelsService> includedModelsService,
                                      final Caller<DMNParseService> parserService,
                                      final Caller<DMNValidationService> validationService,
                                      final Caller<TimeZoneService> timeZoneService,
                                      final Caller<DataObjectsService> dataObjectsService); @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 @SuppressWarnings("unchecked") public void testParseFEELList() { final String source = "source"; clientServicesProxy.parseFEELList(source, serviceCallback); verify(parseService).parseFEELList(eq(source)); }
