Cannot retrieve session data stored in prior request about supertest-session

[rjz]

Hey, @okunoyuki!

Regarding test state, any cookies held by the session should be available from testSession.cookies (see e.g. this test). supertest-session is meant to handle cookie-based sessions transparently; if that's broken, there's a bug.

As far as the problem here, I'm not sure exactly what's up. When you have a moment, could you provide a few more details about the implementation and behavior you're seeing?

1. what middleware is the app using for session management?
2. if you log out res.headers after calling GET /login in the test setup, the _csrf cookie should be present. Is a session cookie (if expected) present as well? And if so, does it (or its backing datastore) contain the expected values?
3. finally, if the cookies sent from the app look correct, are they also present in testSession.cookies?

Thanks in advance!

Thank you for your quick and kind reply! @rjz
I didn't know about testSession.cookies but that sounds convenient!

Looks like we use multiple session-related frameworks(express-session and passport). Maybe we shouldn't use both of them at a time?

var passport = require('passport');
app.use(require('express-session')({ secret: 'keyboard cat', resave: false, saveUninitialized: false }));
app.use(passport.session());

For 2, the _csrf cookie exists in res.headers after calling GET /login (The following is the output that I got). I assume that I can access 'session cookie' using supertest-session(I apologize if it's a totally wrong assumption), but I don't know how. Could you show me how to access session?

{ 'cache-control': 'private,no-store,no-cache,must-revalidate,proxy-revalidate',
  pragma: 'no-cache',
  'set-cookie': 
   [ '_csrf=XXXXXXXXXXXXXXXXXXXXXXXXXX; Path=/',
     'connect.sid=YYYYYYYYYYYYYYYYYYYYYYY; Path=/; HttpOnly' ],
  'content-type': 'text/html; charset=utf-8',
  'content-length': '1394',
  etag: 'W/"572-LEgv480pG9D7SI5tj94/Zg"',
  date: 'Mon, 29 Jan 2018 23:36:59 GMT',
  connection: 'close' }

For 3, testSession.cookies had _csrf cookie with expected values.

Got it—thanks, @okunoyuki!

Depending on what backing store you are using with express-session, it may not be possible (or desirable) to peek into the session from outside the app. But I think we may be able to make this work from the outside.

First thought: since supertest-session will echo any cookies it receives, try dropping .send('cookie', ...) from the test setup:

testSession.get('/login')
  .end(function(err, res) {
    if (err) {
      return done(err);
    }

    testSession.post('/login')
      .type('form')
      .send({
        username: 'xxxxxxxx',
        password: 'xxxxxxxx',
      })
      .end(done);
  });

It looks like the session cookie is being attached correctly (you can see it in the HTTP requests, and it should appear in testSession.cookies['connect.sid'] after the initial request). The next thought, then, would be to make sure the session is being restored correctly inside the app. If you log out req.cookies in the post routes, the connect.sid cookie should match the cookie seen inside the tests. If it doesn't, it's possible that something is missing in the express-session configuration.

Thank you! @rjz
I'm sorry I was pretty busy this week and haven't tried you ideas yet.
I'll try them and get back to you next week!

@rjz
Thank you for your advice!
It worked without .send('cookie', ...). And I found out that there is something wrong with express-session configuration since the connect.sid cookie in the post routes didn't match the one inside the tests.
Since my problem doesn't seem relevant to supertest-session for now, you can close this issue. Thank you so much!

Awesome, @okunoyuki, I'm glad to hear that it's working!

Please do be in touch if you run into any other issues.

csrfToken=body.csrfToken;
expect(body).to.contain.property('csrfToken');
done();
})
.catch((err) => done(err));
});
});
