longuniquename/sequelize-mock

A simple mock interface specifically for testing code relying on Sequelize models

Sequelize Mock

A mocking interface designed for testing code that uses Sequelize.

Documentation at sequelize-mock.readthedocs.io

Install

npm i sequelize-mock --save-dev

Getting Started

The Mock Models created with this library function as drop in replacements for your unit testing.

Start by importing the library

var SequelizeMock = require('sequelize-mock');

Initialize the library as you would Sequelize

var DBConnectionMock = new SequelizeMock();

Define your models

var UserMock = DBConnectionMock.define('users', {
		'email': '[email protected]',
		'username': 'blink',
		'picture': 'user-picture.jpg',
	}, {
		instanceMethods: {
			myTestFunc: function () {
				return 'Test User';
			},
		},
	});

Once Mock models have been defined, you can use them as drop-in replacements for your Sequelize model objects. Data is not retrieved from a database and instead is returned based on the setup of the mock objects, the query being made, and other applied or included information.

For example, your code might look something like this

UserMock.findOne({
	where: {
		username: 'my-user',
	},
}).then(function (user) {
	// `user` is a Sequelize Model-like object
	user.get('id');         // Auto-Incrementing ID available on all Models
	user.get('email');      // '[email protected]'; Pulled from default values
	user.get('username');   // 'my-user'; Pulled from the `where` in the query
	
	user.myTestFunc();      // Will return 'Test User' as defined above
});
