Not able to validate emails within an array

[rajaraodv]

U have a schema where the user has an array of emails. I want to validate that each of these items are valid/invalid. But there are not getting validated. Please see the mocha,should test code here:

require.paths.unshift('./node_modules');
require('should');
var assert = require('assert');

var mongoose = require('mongoose')
, Schema = mongoose.Schema
, mongooseTypes = require("mongoose-types")
, db = mongoose.createConnection(getMongoUrl());

mongooseTypes.loadTypes(mongoose);

var Email = mongoose.SchemaTypes.Email;

/* if we use the below code.. we get: CALL_NON_FUNCTION_AS_CONSTRUCTOR exception

var emailType = mongoose.SchemaTypes.Email;
var Email = new mongoose.Schema({
type: emailType,
unique: true,
required: true,
lowercase: true
});

*/

describe('Schema with just one email; Simple User with an invalid email', function(){
var UserSchema = new Schema({
email: Email
});
var User = db.model('User', UserSchema);
//User.remove({}, function (err) {});

describe('Save invalid email', function(){
it('should throw vaidation error', function(done){
var user = new User({email: 'asdf.com'});
user.save(function(err){
err.message.should.equal('Validation failed');
done();
});
})
})
});

describe('Schema with an ARRAY of emails; User with 1 or more invalid emails', function(){
var UserSchema2 = new Schema({
emails: [Email]
});
var User2 = db.model('User2', UserSchema2);

describe('Save invalid email', function(){
it('should throw vaidation error', function(done){
var user2 = new User2({emails: ["rrr"]});
user2.save(function(err){
console.log(err);
assert.exist(err);
assert.exist(err.message);
assert.equal(err.message, 'Validation failed');
done();
});
})
})
});

function getMongoUrl() {
if (process.env.VCAP_SERVICES) {
var env = JSON.parse(process.env.VCAP_SERVICES);
var obj = env['mongodb-1.8'][0]['credentials'];
}
else {
var obj = {
"hostname": "localhost",
"port": 27017,
"username": "",
"password": "",
"name": "",
"db": ""
}
}
obj.hostname = (obj.hostname || 'localhost');
obj.port = (obj.port || 27017);
obj.db = (obj.db || 'test');

if (obj.username && obj.password) {
    return "mongodb://" + obj.username + ":" + obj.password + "@" + obj.hostname + ":" + obj.port + "/" + obj.db;
} else {
    return "mongodb://" + obj.hostname + ":" + obj.port + "/" + obj.db;
}

}
