Passport Session showing undefined req.user

When im logging in the req.user is displayed as it should, but after navigating to /test , the req.user is undefined.

Why is that?

server.js

var express    = require('express');        // call express
var app        = express();                 // define our app using express
var bodyParser = require('body-parser');
var mongoose = require('mongoose');
var session      = require('express-session');
var router = express.Router();
var Account = require('src/app/models/Users.js');
var Core = require('/src/app/gamemodels/core');
// Init passport authentication
var passport = require('passport');
var Strategy = require('passport-local').Strategy;
require('/src/config/passport')(passport);
var cookieParser = require('cookie-parser')



// required for passport session

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
mongoose.connect('DB');
app.use(cookieParser()) // required before session.

app.use(session({ secret: 'xxxx' }));
app.use(passport.initialize());
app.use(passport.session());






var port = process.env.PORT || 3000;        // set our port


// test route to make sure everything is working (accessed at GET http://localhost:8080/api)
router.get('/', function(req, res) {
    res.json({ text: 'hooray! welcome to our api!' });
});


router.get('/test', function(req,res) {
    console.log(req);
    console.log(req.user);
    res.json(req.user);
});


router.post('/signup', passport.authenticate('local-signup', {
    successRedirect : '/profile', // redirect to the secure profile section
    failureRedirect : '/signup', // redirect back to the signup page if there is an error
}));

router.post('/login', passport.authenticate('local-login'), function(req, res) {

    console.log("executed login!");
    console.log(req.user);
    req.session.user = req.user;

});


});
