Current behavior

I get the following error when running tests using mockgoose:

(node:10262) UnhandledPromiseRejectionWarning: Error [ERR_INVALID_PROTOCOL]: Protocol "http:" not supported. Expected "https:"

(node:10262) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 24)

tests that don't require me to connect to DB will succeed. Ones that need DB connection will fail. (both throw these errors).

Expected behavior

Be able to use mockgoose for tests

Minimal reproduction of the problem with instructions

Application runs perfectly, it seems that once it starts the application going in to the IF statement in the following code from databaseProvider, it goes wrong

useFactory: async () => {
            (mongoose as any).Promise = global.Promise;
            if (process.env.NODE_ENV !== 'test') {
                                // when running tests, it gets here, tested with console.log
                const mockgoose = new Mockgoose(mongoose);
                mockgoose.helper.setDbVersion('3.6.0');
                mockgoose.prepareStorage()
                    .then(async () => {
                        await mongoose.connect('mongodb://localhost:27017/myAppTest', {
                            useMongoClient: true
                        });
                    }).catch(()=>{ console.log('ERR! Unable to prepare test database')});
            } else {
                await mongoose.connect(process.env.dbUrl ? process.env.dbUrl : 'mongodb://localhost:27017/myApp', {
                    useMongoClient: true
                });
            }
            return mongoose;
        }

Hi @MiVvlt,
Thanks for reporting. cc @vladotesanovic

@MiVvlt @kamilmysliwiec

Yes there is problem with Mockgoose library,

@MiVvlt

You will need to change package in package.json and import in provider.database.ts

from:
mockgoose to mockgoose-fix

"mockgoose-fix": "^7.3.5",

and

import { Mockgoose } from 'mockgoose-fix';

I will update docs.nestjs.com and example in next days.
