javascript - Change async/await to Promise

Question

I would like to change the following async/await code

const mongoose = require('mongoose')
const supertest = require('supertest')
const app = require('../app')

const api = supertest(app)

test("total number of blogs", async () => {
  const response = await api.get('/api/blogs')
  
  expect(response.body).toHaveLength(1)
})
      

afterAll(() => {
  mongoose.connection.close()
})

to a Promise like this:

const mongoose = require('mongoose')
const supertest = require('supertest')
const app = require('../app')

const api = supertest(app)

test("total number of blogs", () => {
  api.get('/api/blogs')
    .then( response => {
      expect(response.body).toHaveLength(1)
    })
})


afterAll(() => {
  mongoose.connection.close()
})

I could not manage to solve it correctly and I keep getting an error message:

To clarify @jonrsharpe's comment you should return the promises from your test function:

test("total number of blogs", () => {
  return api.get('/api/blogs')
    .then( response => {
      expect(response.body).toHaveLength(1)
    })
})
