Testing using Nock

[sparkyfen]

I'm trying to test my code I've written using supertest and nock but I'm getting a state not matching error.

My package.json dep section:

{
  "oauthio": "^0.3.1",
  "express": "~4.0.0",
  "express-session": "~1.0.2"
}

My package.json dev section:

{
  "nock": "^0.48.2",
  "querystring": "^0.2.0",
  "should": "~3.3.1",
  "supertest": "~0.11.0"
}

I've set up some nock listeners on two endpoints.

My server-side code is:

exports.index = function(req, res) {
  // .....
  OAuth.auth('facebook', req.session, {
      code: code
  }).then(function (reqObj) {
    return reqObj.get('/me');
  }).then(function (info) {
    console.log(info);
    // ......
  });
};

My test:

describe('My Test', function() {
  beforeEach(function (done) {
    // .....
    nock('https://oauth.io')
    .post('/auth/access_token', {
      code: 'someCode',
      key: config.oauth.appKey,
      secret: config.oauth.appSecret
    })
    .reply(200, {
      access_token: 'result_access_token',
      expires_in: 'someday',
      request: {},
      state: 'unique_id',
      provider: 'facebook'
    });
    nock('https://oauth.io')
    .matchHeader('oauthio', qs.stringify({
      k: config.oauth.appKey,
      access_token: 'result_access_token'
    }))
    .get('/request/facebook/me')
    .reply(200, {
      email: 'mockUser@gmail.com',
      first_name: 'Foo',
      last_name: 'Bar'
    });
    done();
  });
  afterEach(function (done) {
    // .....
  });
});

it('should respond with a successful login', function(done) {
    request(app)
      .post('/api/user/login/facebook')
      .set('cookie', cookie)
      .send({code: 'someCode'})
      .expect(200)
      .expect('Content-Type', /json/)
      .end(function(err, res) {
        if (err) return done(err);
        res.body.should.be.instanceof(Object);
        done();
      });
  });

However, my response on the test is:

[Error: State is not matching]

Any thoughts on why I'm getting this error?
