buildGeneratesSection: options => {
    const schemaObject: GraphQLSchema = options.schemaAst ? options.schemaAst : buildASTSchema(options.schema);
    const baseVisitor = new BaseVisitor(options.config, {
      scalars: buildScalars(schemaObject, options.config.scalars),
    });

    const getAllFragmentSubTypes = (possbileTypes: string[], name: string, suffix: string): string[] => {
      if (possbileTypes.length === 0) {
        return [];
      } else if (possbileTypes.length === 1) {
        return [
          baseVisitor.convertName(name, {
            useTypesPrefix: true,
            suffix: suffix,
          }),
        ];
