How can I close a dynamoose instance?

Summary:

we are setting up some automated tests with dynalite and dynamoose and are hitting a show-stopper: after the test execution a process keeps running. If we just start/stop the dynalite instance (without any interaction with dynamoose) there are no running processes left. Some process keeps running as soon as there is an interaction with dynamoose.

Code sample:

Schema

// Code here

see below

Model

// Code here

see below

General

// dynamooseHelper.js
const dynamoose = require('dynamoose');
const dynalite = require('dynalite');
dynamoose.AWS.config.update({
  accessKeyId: 'AKID',
  secretAccessKey: 'SECRET',
  region: 'us-east-1'
});

module.exports.getRunningDynaliteInstance = async () => {
  if (isRunning) {
    throw new Error(`dynalite is running`);
  }
  const portNumber = getPortNumber();
  dynaliteInstance = new dynalite();
  await dynaliteInstance.listen(portNumber);
  dynamoose.local(`http://localhost:${portNumber}`);
  isRunning = true;
  return portNumber;
}

module.exports.stopDynaliteInstance = async () => {
  if (!isRunning) {
    throw new Error(`dynalite is not running`);
  }
  await dynaliteInstance.close();
  isRunning = false;
}

function getCatModel() {
  return dynamoose.model('Cat', {id: Number, name: String})
}

module.exports.CreateCat = async (id, name) => {
  const Cat = getCatModel();
  const cat = new Cat({ id: id, name: name});
  await cat.save();
  return cat;
};

module.exports.GetCat = async (id) => {
  const Cat = getCatModel();
  const cat = await Cat.get(666);
  
  return cat;
};

// test/startStopTest.js   
const assert = require('chai').assert;
const dynaliteHelper = require('../dynamooseHelper');

describe('start stop bad cat', async () => {
  before(async function () {
    await dynaliteHelper.getRunningDynaliteInstance();
  });

  after(async function () {
    await dynaliteHelper.stopDynaliteInstance();
  })
  it('dynalite start stop', () => {
    const garfield = dynaliteHelper.CreateCat(666, 'Garfield');  // comment out these lines here
    assert(garfield != null, 'garfield no lasagne');  // comment out these lines here
    const badCat = dynaliteHelper.GetCat(666);  // comment out these lines here
    assert(badCat != null, 'bad cat');   // change to assert(true)
  })  
})

Current output and behavior:

After the test, a process keep running. If you comment the lines above and change the assertion, there is no process running after the test. While still acceptable for a developer PC, we cannot use this for CI and automated testing, if there is a process running after each test.

Expected output and behavior:

When closing the dynalite server, the dynamoose instance should also close. OR a dynamoose.close() function or similar is needed.

Environment:

Operating System: Ubuntu Operating System Version: 18.04 Node.js version (node -v): v9.11.2 NPM version: (npm -v): 6.9.0 Dynamoose version: “dynamoose”: “^1.8.0” Dynamoose Plugins:
“dynalite”: “^2.3.1” (is this to be considered a dynamoose plugin?)

Dynamoose Plugins:

• Yes, I believe that one or multiple 3rd party Dynamoose plugins are effecting this issue
• No, I believe this issue is independent of any 3rd party Dynamoose plugins I’m using
• Unknown, I’m unsure if Dynamoose plugins are effecting this issue
• [?] I am not using any Dynamoose plugins

You can download a working test project here. https://www.dropbox.com/s/s5bt9o78908vcwg/dynalite-startStopTest.zip?dl=0 Just run ‘npm run test’ or press F5 in VS Code.

@bhw1994 Yes. After calling dynamoose.model by default Dynamoose will attempt to create/verify that the table exists in DynamoDB. You can disable this behavior in the options object. But otherwise this is the default (and expected) behavior.
