jest supertest with express-session

I want to test my routes with jest but I don't know how to mock or simulate a session in my test to pass the first if line 2

app.get('/getMailSuiviList', (req, res) => {
    if (req.session.infoUser != undefined) {
        let mail = require('../models/M_Email')
        mail.indexSuiviByDept(req.session.infoUser.deptID)
            .then(dataMails => {
                res.json(dataMails)
            })
            .catch(e => {
                res.json('Erreur: ' + e)
            })
    } else {
        req.session.error = 'Vous devez vous connecter'
        res.redirect('/')
    }
})

Can someone help me?

Could not find any way to do this with jest or supertest so I did it directly in Express:

First, my routes/controllers are in their own files and I app.use() them in my server.js file. So instead of importing my server and test it I import my routes individually and test them separately. This allows me to inject a fake session middleware just for testing.

Say for example you have your route above in its own file:

// mail.js

const express = require('express');

const router = express.Router();

router.get('/getMailSuiviList', (req, res) => {
    if (req.session.infoUser != undefined) {
        let mail = require('../models/M_Email')
        mail.indexSuiviByDept(req.session.infoUser.deptID)
            .then(dataMails => {
                res.json(dataMails)
            })
            .catch(e => {
                res.json('Erreur: ' + e)
            })
    } else {
        req.session.error = 'Vous devez vous connecter'
        res.redirect('/')
    }
})

module.exports = router;

Now in my test I do this:

const mailRouter = require('../mail.js');
const express = require('express');
const supertest = require('supertest');

const app = express();

const fakeSessionMiddleware = (req, res, next) => {
    req.session = {
        infoUser: {
            deptID: 1
        }
    }
    next();
}

app.use(fakeSessionMiddleware);
app.use(mailRouter);


describe('mail',() => {
    it('should get mail', async () => {
        // write your test here...
    });
});

Just in case you haven't, check supertest-session package, it's a wrapper around supertest and provides session auth in requests:

supertest-session
