Connecting in globalSetup doesn't work

[kibebr]

Hi, I have multiple test files that use Mongo. I would like to connect only once (in the globalSetup.ts), and disconnect only once, after every test is done, on globalTeardown.ts.

I tried following the steps from https://github.com/shelfio/jest-mongodb/issues/212

But it doesn't seem to work.

This is my globalSetup.ts. It seems to be working fine, the MONGO_URL is always set.

./server/tests/__scripts__/globalSetup.ts

// @ts-nocheck
import mongoose from 'mongoose'
import mongoSetup from '@shelf/jest-mongodb/setup'
import dotenv from 'dotenv'

dotenv.config()

module.exports = async () => {
  await mongoSetup()

  console.log('env is: ', process.env.MONGO_URL)

  await mongoose.connect(process.env.MONGO_URL as string, {
    dbName: 'jest',
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useCreateIndex: true,
    useFindAndModify: false
  })
}

However, in all of my tests, Mongo is just unresponsive. Jest throws the "Exceeded timeout of 5000ms for a hook" error.

It does work, however, if I connect inside the test file using beforeAll:

./server/tests/repositories/notificationRepository.test.ts

beforeAll(async () => {
  await mongoose.connect(process.env.MONGO_URL as string, {
    dbName: 'jest',
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useCreateIndex: true
  })
})

This is my config: ./server/tests/jest.base.config.js

const merge = require('merge')
const tsJestPreset = require('ts-jest/jest-preset')
const mongoDbMemoryPreset = require('@shelf/jest-mongodb/jest-preset')

module.exports = merge(tsJestPreset, mongoDbMemoryPreset, {
//   testEnvironment: 'node',
  setupFilesAfterEnv: ['./jest.setup.js'],
  modulePaths: ['../'],
  maxWorkers: 1,
  globalSetup: './__scripts__/globalSetup.ts',
  globalTeardown: './__scripts__/globalTeardown.ts',
  globals: {
    'ts-jest': {
      tsConfig: './tsconfig.json'
    }
  }
})

Am I missing something obvious? Is there a way I can connect to Mongo inside globalSetup and use the connection throughout my test files?

Thanks!

I am having this same issue.
