Mongoose Fixture Loader

A promise fixture loader for Mongoose.

1. Load a single object

   loadFixture(UserModel, userObject);

2. Load an array of objects

   loadFixture(UserModel, arrayOfUserObjects);

3. Load a sequence of objects

   loadFixture(UserModel, userObject)
     .then((userInstance) => {
       loadFixture(BookModel, bookObjectRelatedToUserObject)
     });

4. Load objects in parallel

   Promise.all([
     loadFixture(UserModel, userObject),
     loadFixture(CatModel, catObject),
     loadFixture(DogModel, dogObject)
   ]);

Installation

npm install --save mongoose-fixture-loader

Usage

1. Assume you have a user model file src/models/user-model.js as the following.

   const mongoose = require('mongoose');
    
   const UserSchema = new mongoose.Schema({
     firstName: { type: String, required: true },
     lastName: {type: String, required: true },
     email: { type: String },
     created: { type: Date, default: Date.now }
   });
    
   module.exports = mongoose.model('User', UserSchema);

2. Create a fixture file test/fixtures/user.js to export a JSON object,

   module.exports = {
     firstName: 'John',
     lastName: 'Doe',
     email: '[e-mail]'
   };

   or an array of JSON object.

   module.exports = [
     {
       firstName: 'John',
       lastName: 'Doe',
       email: '[e-mail]'
     },
     {
       firstName: 'Alice',
       lastName: 'Bob',
       email: '[e-mail]'
     }
   ];

3. In your test file test/index-test.js, you can load and test your fixture.

   const expect = require('chai').expect;
   const mongoose = require('mongoose');
   const loadFixture = require('mongoose-fixture-loader');
   const UserModel = require('../src/models/user-model.js');
   const user = require('./fixtures/user.js');
    
   // Mongoose default promise is deprecated
   mongoose.Promise = global.Promise;
    
   describe('a test suite', () => {
     mongoose.connect('mongodb://localhost/mongoose-fixture-loader-test');
    
     before((done) => {
       loadFixture(UserModel, user)
         .then((userInst) => {
           done();
         })
         .catch((err) => {
           done(err);
         });
     });
    
     after((done) => {
       UserModel.remove({})
         .then(() => {
           return mongoose.connection.close();
         })
         .then(() => {
           done();
         })
         .catch((err) => {
           done(err);
         });
     });
    
     it('should find John', (done) => {
       UserModel.find({})
         .then((users) => {
           expect(users[0].firstName).to.equal('John');
           done();
         })
         .catch((err) => {
           done(err);
         });
     });
   });
