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.

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.
