Having trouble setting up mongodb-memory-server 8 to work with jest

I am currently working on integrating the latest version of mongodb-memory-server with jest on a node express server. While following the guide provided in the mongodb-memory-server documentation (), I encountered some gaps that I am struggling to fill in.

To document my progress, I have created a repository with my attempts to piece everything together: https://github.com/jimmythecode/mongodbmemoryserver-guide

Despite my efforts, I have been unable to find any updated instructions online for the current version of mongodb-memory-server. Any assistance would be greatly appreciated.

Answer №1

Below is the configuration I am using with the "mongodb-memory-server" version "^8.5.2" and "jest" version "^28.1.0". Please review

import { MongoMemoryServer } from "mongodb-memory-server";
import mongoose from "mongoose";


let mongo: any;
beforeAll(async () => {
  process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

  mongo = await MongoMemoryServer.create();
  const mongoUri = await mongo.getUri();

  await mongoose.connect(mongoUri);
});

beforeEach(async () => {
  const collections = await mongoose.connection.db.collections();

  for (let collection of collections) {
    await collection.deleteMany({});
  }
});

afterAll(async () => {
  jest.setTimeout(20000)
  await mongo.stop();
  await mongoose.connection.close();
});

Answer №2

Success! I was able to get everything up and running smoothly. For detailed instructions, check out the latest updates in this branch. Hopefully, this can be of assistance to others facing the same issue.
