Mock Sequelize

A simple mocking interface designed for applications that use the sequelize.js library. This library was forked from https://github.com/BlinkUX/sequelize-mock This library is specifically for testing code relying on Sequelize models and is therefore a very bare library at the moment. The more complex functionality of Sequelize has not been included and the library will likely be fleshed out to include this functionality as needed.

Once Mock models have been defined, the mock models should be 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.

Example Usage

// Import the mock library
var SequelizeMock = require('mock-sequelize');
 
// Setup the mock database connection
var DBConnectionMock = new SequelizeMock();
 
// Define our Model
var UserMock = DBConnectionMock.define('users', {
        'email': '[e-mail]',
        'username': 'blink',
        'picture': 'user-picture.jpg',
    }, {
        instanceMethods: {
            myTestFunc: function () {
                return 'Test User';
            },
        },
    });
 
// You can also associate mock models as well
var GroupMock = DBConnectionMock.define('groups', {
    'name': 'My Awesome Group',
});
 
UserMock.belongsTo(GroupMock);
 
// From there we can start using it like a normal model
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');      // '[e-mail]'; 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
    
    user.getGroup(); // Will return a `GroupMock` object
});
