A Node.js + Mongoose + Jest sample project that demonstrates how to test mongoose operations using Jest with an in-memory database.

This repo was build as an example for my article Testing Node.js + Mongoose with an in-memory database.

What you need to run this project:

• Node.js

(MongoDB is not required because it'll run in memory, handled by the package mongodb-memory-server).

npm install

npm test

Feel free to contribute to this project either by leaving your comments and suggestions in the Issues section or creating a PR. More and diverse test examples are always useful. Make sure to take a look at Jest docs and the existent examples to avoid repeating.

Main tools used in this project:

• Mongoose
• Jest
• mongodb-memory-server package by @nodkz

Also take a look at mongodb-memory-server-global to download mongod's binary globally and mongodb-memory-server-core if you'll run the test on a server that already has mongod installed.
