Node Populator for MongoDB

A simple library used to populate a MongoDB database with native driver. Usefull for unit tests.

How to install ?

npm install node-populator-mongodb

Example usage

Create testing data

'use strict;';

var ObjectID = require('mongodb').ObjectID;
var DBRef = require('mongodb').DBRef;

var getDBRef = function(collectionName, id) {
    return new DBRef(collectionName, id, 'populator_test');
};

module.exports = [
        {
            _id: new ObjectID("200000000000000000000001"), 
            name: "Project 1", 
            customer: getDBRef("customer", "300000000000000000000001") 
        },
        {
            _id: new ObjectID("200000000000000000000002"), 
            name: "Project 2", 
            customer: getDBRef("customer", "300000000000000000000002") 
        }
    ];

'use strict;';

var ObjectID = require('mongodb').ObjectID;
var DBRef = require('mongodb').DBRef;

var getDBRef = function(collectionName, id) {
    return new DBRef(collectionName, id, 'populator_test');
};

module.exports = [
        {_id: new ObjectID("300000000000000000000001"), name: "Customer 1" },
        {_id: new ObjectID("300000000000000000000002"), name: "Customer 2" }
    ];

• Each exported key (as customer, project) is corresponding to a MongoDB collection.
• In each collection, you must define an array containing wished records.

Create unit test

• We'll use mocha to run unit tests.

'use strict;';

var data = require('testing-data'),
    PopulatorMongoDB = require('node-populator-mongodb'),
    CustomerService = require('customer-service');

var customerService = new CustomerService();

var dbUri = 'mongodb://localhost:27017/populator_test';

/**
 * Unit tests to validate GenericDaoMongoose.
 */
describe('Customers test', function () {

    /**
     * Before each test, drop the collection then populate.
     */
    beforeEach(function (done) {
        this.timeout(3000);
        var populator = new PopulatorMongoDB(dbUri, data);
        populator.populate(done);
    });

    /**
     * Create new object(s).
     */
    describe('create', function () {
        it('create a new customer', function (done) {
            customerService.create({name: 'customer test new 1'}, function (err, result) {
                    assert.equal(err, null);
                    assert.equal(result.name, 'customer test new 1');
                    done(err);
                }
            );
        });
	});
});

Run your tests
