Write tests for database operations and its functions

[powilliam]

To avoid the necessity of have mongod locally installed or use its cloud services i pretend to use an implementation of MongoDB for memory storage.

Create a mock for the database is a great option to test it

Is it worth to use a testing database version to do real tests for database operations?
Or is it enough to test with mock. If it is database operations, we might need a database, right? 🤷🏻‍♂️

[EduardoAraujoB]

Maybe define a SQLite database for tests is a great option, but we will have problems beacuse the test for database operations will be assyncronous

That's why i'm using MongoDB Memory Server. It uses the latest mongod binary located onnode_modules/.cache/mongodb-binaries to setup a MongoDB memory database. jest-mongodb uses it under the hood. By this way we don't have to setup a real database.

To test, we could just create a local database with Mongo Article: setup a local MongoDB Connection
