hey there! I'm having issues with getting tests to pass with the models exercises.

Steps taken

click to see my steps

1. git clone url
2. npm install
3. navigate to the exercises/models directory and run this
4. npm test exercises/models/__test__/
5. tests pass even though I did not enter code for tests

on the connect.js file I entered this

const mongoose = require('mongoose')
mongoose.Promise = global.Promise

const connect = () => {
    return mongoose.connect('mongodb://localhost:27017/usersDatabase')
}
module.exports = connect

If you use yarn test, instead of npm, the tests run as expected.

does this mean I'd have to do yarn install (instead of npm install)? And use yarn throughout the project? Or only use yarn to run the tests?

I'm just getting my feet wet with yarn and did npm install (mostly out of habit). I would assume that yarn would still install the same packages and package dependencies. So for this I'm just using yarn to run the tests.

I met similar problems running tests for exercise. Some tests passed even before I write a code with an error message "server instance pool was destroyed". I modified afterEach call in testconfig.js as below and now it works fine.

afterEach(async done => {
  await mongoose.disconnect()
  return done()
}

NPM is for sure conflicting with something when i used YARN everything worked flawlessly

to avoid unexpected behaviour use YARN
