Jasmine `expect` never wrong in superagent `end`

Question

My code doesn't do what it should. All the Jasmine expect() that are in a supertest end() callback function pass, even if they should not.

const app = require('../server')
const request = require('supertest')

describe('Client', function() {
  const agent = request.agent(app)

  it('connects to the server', function() {
    agent.post('/users/register/foobar').end(function(err, res) {
      done()
      expect(true).toBe(false) // Doesn't fail
    }
  })
})

Extract from package.json:

"devDependencies": {
  "jasmine": "^2.4.1",
  "supertest": "^2.0.0"
}

The actual versions given by npm list are [email protected] and [email protected].

My guess is that end() never calls its function, but I just started yesterday with all that and I'm not sure what to do to solve the problem.

Do you see my error?

Edit

As suggested, I switched lines to put the done() at the end, still no change, though.

I think you're wrong to use the function "done". Try:

it('connects to the server', function(done) {
agent.post('/users/register/foobar').end(function(err, res) {
  expect(true).toBe(false); // Doesn't fail
  done();
}  })
