How to write test with supertest

[7elven]

I used supertest to write api test with express project
Now, I want to change from express to hyper-express but test doesn't work

Express Project

app.ts

import express from 'express'
const app = express()
app.use(express.json({ limit: '50mb' }))
app.use(express.urlencoded({ extended: false }))

export default app

Hyper Express

app.ts

import HyperExpress from 'hyper-express'

const app = new HyperExpress.Server({ max_body_length: 50 * 1000000 }) // 50mb

export default app

---

Test

router.test.ts

import request from 'supertest'

import app from '../../../app'

describe('GET /', () => {
  it('Should response status code 200', async () => {
    const res = await request(app).get('/')
    expect(res.status).toEqual(200)
  })
})

afterAll((done) => {
  done()
})

This test is work on express but on hyper-express is show error

TypeError: app.address is not a function

How to fix this? or How Hyper-Express write api test?

HyperExpress is not 100% drop-in compatible with ExpressJS and it seems that some of the logic is trying to call a method called Server.address() which currently is not implemented with HyperExpress.

You can add this method yourself onto your app if you understand the behavior of this method or wait for future updates which may add compatibility for this method.
