Can't get authorization in route testing

I have a route which requires authentication. However when I try to test this route, I'm always getting 401 (unauthorized). How can I send my user with the route so that I am authenticated?

I'm using Google passport authentication.

This is my test:

const assert = require('chai').assert;
const expect = require('expect');
const should = require('should');
const liveScore = require('./../lib/live-score');
const superagent = require('superagent');
const theAccount = {
  name: 'Stijn Aerts',
  role: 'admin',
  id: '115039452833383267752'
};

describe('live-score', function() {
  it('should return 200 authorized', function (done) {
    superagent
      .get('http://localhost:3000/api/live-score')
      .send(theAccount)

      .set('Accept', 'application/json')
      .set('Content-Type', 'application/json')

      .end(function (err, res) {
        expect(200, done);
        assert.equal(res.status, 200) ;
        done();
      });
  });
});

Routes.js:

...
router.get('/api/live-score', loggedIn, liveScore.getData);
...

function loggedIn(req, res, next) {
  if (req.user) {
    next();
  } else {
    res.status(401).json({message: 'Session unavailable'});
  }
}
...
