In Synap, the term, quiz, is referenced as the Test class. Tests store information on the questions they contain, and point to a number of other related objects. When querying for a specific test, we will return a 'data transfer object', shortened to DTO. This object only contains fields that are relevant to the task at hand.

interface TestDTO {
  objectId: string;
  createdAt: Date;
  updatedAt: Date;
  title: string;
  slug: string;
  description: string;
  isSpacedRepetition: boolean;
  isGenerated: boolean;
  tags: string[];
  totalQuestions: number;
  questions: TestDTO.Question[];
  author: TestDTO.User;
  
}
namespace TestDTO {
  export interface Question {
    objectId: string;
    createdAt: Date;
    updatedAt: Date;
    stem: string;
    options: Option[];
    optionType: OptionType;
    feedback: string;
    tags?: string[];
    image?: File;
    feedbackImage?: File;
    bank?: QuestionBank;
    emqGroup?: EmqGroup;
    emqGroupOrder?: number;
  }

  interface Option {
    phrase: string;
    isCorrect: boolean;
    rank?: number;
  }

  type OptionType = 'phrase' | 'phrase:multipleCorrect' | 'phrase:ranked'

  interface EmqGroup {
    objectId: string;
    createdAt: Date;
    updatedAt: Date;
    instructions: string;
    title?: string;
    feedback?: string;
    image?: File;
  }

  export interface User {
    objectId: string;
    createdAt: Date;
    updatedAt: Date;
    name: string;
    slug: string;
    email: string;
    bio?: string;
    attr?: { [key: string]: any };
    emailVerified?: boolean;
    profilePicture?: File;
  }

  export interface File {
    __type: 'Pointer';
    _name: string;
    _url: string;
  }

  export interface QuestionBank {
    objectId: string;
    createdAt: Date;
    updatedAt: Date;
    name: string;
  }
}
