npm install mongoose-mock
mongoose-mock is used for swapping out mongoose in unit tests. Use something like proxyquire to change the dependency.
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
var User = new Schema({});
User.statics.createAndSave = function (props, callback) {
var user = new User(props);
user.save(function(err, result) {
callback(err, result);
});
return user;
};
module.exports = mongoose.model('User', User);var mongooseMock = require('mongoose-mock'),
proxyquire = require('proxyquire'),
chai = require('chai'),
expect = chai.expect,
sinon = require('sinon'),
sinonChai = require("sinon-chai");
chai.use(sinonChai);
describe('User', function () {
var User;
beforeEach(function () {
User = proxyquire('../../../model/User', { 'mongoose': mongooseMock });
});
describe('.createAndSave', function () {
it('saves the user', function () {
var callback = sinon.spy();
var user = User.createAndSave({ title: 'Mr', lastName: 'White' }, callback);
expect(user.save).calledOnce;
});
});
});
