Unable to send authenticated request in tests using Jest, Supertest, Passport, Koa2 Again

Question

I've been trying to use internetross's March 2018 answer to no avail. I too am using Jest, Supertest, and in my case Koa and Passport.

Using REST client in Visual Studio, no problem. The session gets pass through, Passport authenticates, and I get data. But in Jest, no go. I can login fine, I get Koa:sess fine, but I can't make an authenticated request.

Anybody see anything with the below?

const supertest = require('supertest')
const app = require('../app.js')
const http = require('http')

const agent = supertest.agent((http.createServer(app.callback())))

let session = null

beforeAll(async () => {
  const response = await agent
  .post('/v1/users/login')
  .set({'content-Type': 'application/json'})
  .send({ username: 'username', password: 'password' })

  session = response.headers['set-cookie'][0]
               .split(',')
               .map(item => item.split(';')[0])
               .join('; ')

  console.log(stringify(session))

  expect(response.status).toEqual(200)
})

describe('user tests', () => {
  test('data', async () => {
    const response = await agent.get('/v1/users/data?dataIdId=140934')
    .set('Cookie', session)

    expect(response.status).toEqual(200)
  })
})

Of course another question is why this is even necessary if you are using agent. But I've made no progress on that either.

Thanks in advance.

Are the smart single quotes intentional? Perhaps you should edit them to be straight single quotes so they aren't distracting to readers. e.g.: ‘supertest’ should be 'supertest' and all other occurrences. — Wyck
Nope. B products of me writing the text in a Bear on a Mac before pasting. I'll fix them. — Crivens
How do you handle a session in a middleware? Is it stored locally or in memory? Supertest might reboot a app instance in a background after passed test, so if you keep sessions in memory you will lose it. — l2ysho
That's a good idea to investigate. I'll look into it more tomorrow. I'm using passport-local. Here's the very simple code setting it up: passport.use( new LocalStrategy(options, (username, password, done) => { User.findOne({ username: username }) .then(user => { if (!user) return done(null, false) if (password === user.password) { return done(null, user) } else { return done(null, false) } }) .catch(err => { return done(err) }) }) ) — Crivens

After lots of sleuthing, I finally found the answer. Courtesy of https://github.com/facebook/jest/issues/3547#issuecomment-397183207.

I had to replace

session = response.headers['set-cookie'][0]
               .split(',')
               .map(item => item.split(';')[0])
               .join('; ')

with

  response.headers['set-cookie'][0]
    .split(',')
    .map(item => item.split(';')[0])
    .forEach(c => agent.jar.setCookie(c));

Big sigh.
