donky

A mongoose fixture library to generate documents for testing purpose. It can be used to generate documents that have reference to other documents as well as documents having embedded documents.

Features

• Multiple documents generation
• Document reference support
• Sub-document support
• Generate mock field values (using chancejs)

Installation

$ npm install donky --save-dev

Usage

// mongoose schema
var UserSchema = new mongoose.Schema({
  username: { type: String },
  email: { type: String },
  isActive: {
    type: Boolean,
    default: true
  },
  isAdmin: {
    type: Boolean,
    default: false
  }
});
 
var CommentSchema = new mongoose.Schema({
  author: { type: String },
  comment: { type: String }
});
 
var PostSchemma = new mongoose.Schema({
  post: { type: String },
  author: {
    type:  mongoose.Schema.ObjectId,
    ref: 'User'
  },
  comments: [CommentSchema],
  likes: [{
    type: mongoose.Schema.ObjectId,
    ref: 'User'
  }]
});
 
// Usage
var mongoose = require('mongoose');
var Donky = require('donky');
var donky = new Donky(mongoose);
 
// create a factory for schema User with name admin
donky.factory()
  .schema('User', 'admin')
  .field('email', donky.gen.email())
  .field('password', donky.gen.string());
 
// create a factory for schema User with name user
donky.factory()
  .schema('User', 'user')
  .field('email', donky.gen.email())
  .field('password', donky.gen.string());
 
donky.factory()
  .schema('Comment', 'comment-post1')
  .field('author', donky.gen.twitter())
  .field('comment', donky.gen.paragraph());
 
donky.factory()
  .schema('Post', 'post1')
  .field('post', donky.gen.paragraph())
  .field('author', donky.ref('user'))
  .field('comments', donky.embed('comment-post1#'))
  .field('likes', donky.ref('user#'));
 
// create a single document based on the value
// supplied by the admin factory. Calling donky.create will
// save the document to mongodb. donky.create returns a promise.
var adminPromise = donky.create('admin');
 
// create 3 documents based on the user factory.
var userPormise = donky.create('user', 3);
// create 7 documents based on the comment-post1 factory.
var commentsPromise = donky.create('comment-post1', 7);
var postPromise = donky.create('post1');
 
// doing the test
postPromise.then(function(post) {
  // expectations goes here
  done();
}).fail(function(err) {
  done(err);
});

Reference

The method donky.ref(name, path) is used to refer field to other document that has been created, therefore the creation sequence matters!. The method takes two arguments: the factory name and the path to be refer to (the default is _id). The .field('author', donky.ref('user')) tells that that the author field is referring to the document created from user factory.

Multiple references

To add multiple references, simply use # char to indicate that the specified field will be filled by an array of references, e.g., .field('likes', donky.ref('user#')) says field likes will be filled with an array of _id of document generated from the user factory.

Sub-document

donky.embed(name) embeds a sub-document created from the passed name factory in the similar manner to donky.ref. donky.embed takes only one parameter: the name of the factory where the document is generated from.

Multiple sub-documents

Similar to donky.ref, the char # is used to mark that multiple sub-documents will be embedded.
