Unable to delete database while the process is running

[tommysanterre]

I want to replace the database with a new copy after each of my e2e test. But when I try to delete the current database the operation is denied. I close the database and disconnect but I still get the error. It only happens when using tungus. Using tingodb directly does not have the same issue.

var fse = require('fs-extra');
var Db = require('tingodb')().Db;
require('tungus');
var mongoose = require('mongoose');

var db = new Db('db', {});
mongoose.connect('tingodb://db');

var mongooseSchema = new mongoose.Schema({name: String});
var Person = mongoose.model('Person', mongooseSchema);

Person.create({name: 'toto'}, function (err) {
  if (err) {
    console.log(err);
  } else {
    mongoose.disconnect(function (err) {
      if (err) {
        console.log(err);
      } else {
        db.close(function (err) {
          if (err) {
            console.log(err);
          } else {
            fse.remove('db', function (err) {
              console.log('Trying to delete db');
              if (err) {
                console.log(err);
              } else {
                console.log('db deleted');
              }
            });
          }
        });
      }
    });
  }
});

Outputs
