I'm trying to test the functionality of a mongoose plugin. But when I save an "any" model that implements the plugin, I never get a response from the promise to save.

I tried to increase the mocha timeout --timeout 500000 to see if I throw some error, but always ends up releasing the same mocha timeout error. I think that when I create the model during the test, it doesn't connect to the BD because if I do it with an imported model this error doesn't occur, but from a test point of view I shouldn't use logic models and try to make it as similar as possible to an integration test.

Plugin code:

module.exports.myPlugin = (schema, options) => {



const mySchema = {

    someField: {

        type: mongoose.SchemaTypes.String,

    }

};

mySchema[options.fieldName] = [OrderLine.obj];

schema.add(mySchema);



const someFunction = function (orderLines) {

    // TODO: Important things.

};



schema.pre('save', function (next) {

    this.someField = someFunction();

});



schema.pre('update', function (next) {

    this.someField = someFunction();

});

};

Test Code:

import {myPlugin} from "../../../api/core/plugins";



const chai = require('chai');

const sinonChai = require("sinon-chai");

const chaiAsPromised = require('chai-as-promised');

const expect = chai.expect;

chai.use(chaiAsPromised);

chai.use(sinonChai);



const mongoose = require('mongoose');



const MONGO_URL = 'mongodb://username:password@127.0.0.1:27017/develop?authSource=admin';





describe('Test some important plugin', () => {



    let db;

    let ModelTest;



    before((done) => {



        mongoose.connect(MONGO_URL, {useNewUrlParser: true});

        db = mongoose.connection;

        db.on('error', console.error.bind(console, 'connection error:'));

        db.once('open', function callback () {

            const modelTestSchema = new mongoose.Schema({

                name: {

                    type: mongoose.SchemaTypes.String

                },

            });

            modelTestSchema.plugin(myPlugin, {fieldName: 'customField'});

            ModelTest = mongoose.model('ModelTest', modelTestSchema);

            done();

        });



    });



    after(function (done) {

        db.close();

        done();

    });



    it('should execute some important logic', function () {



        let model = new ModelTest({

            customField: 'my custom field value',

            name: 'test model name'

        });

        try {

            let promise = model.save();

            return Promise.all([

                expect(promise).to.eventually.be.fulfilled,

            ]);

        } catch (e) {

            console.log(e);

            return e;

        }

    });



});
