            I am trying to write a sample application for POC of mongodb-memory-server but unfortunately its not working. I checked several links and blogs but seems like code working for all is not working for me. Jest test times out even after increasing timeout to 1 min. getConnectionString or getUrl both times out. I suspect this mongodb-memory-server never starts.

I should probably note that this is my first real JavaScript project and I'm learning the test tooling as I go.

            In unit tests, you should mock all necessary dependencies for AuthService. It's not e2e test, you shouldn't initialize MongooseModule here. Your beforeEach should look like that:

            How to get Jest working with an in-memory MongoDB server?
            Asked 2019-Dec-24 at 05:40

            I am making my first tentative steps into modern JS development, and to do so, I am writing an app, with the intention of running it on Mongo Stitch. I am trying to stick to TDD-ish development, partly because it is good practice, and partly because it is much easier to run things locally than in the Stitch environment.

            I have a working Docker/Alpine environment, and it runs unit tests against Stitch functions fine using Jest. However, I am now writing functions where the conditionals/logic are in Mongo, so unit tests are not enough to protect against regressions.

            My original plan was to spin up a MongoDB 4.0 instance in Docker Compose, and then work out how to connect to it in Jest. However, the Jest docs have pointed me to an in-memory MongoDB, which sounds pretty good. Unfortunately it seems non-trivial to set up, and I am bumping into a number of errors.

            I am using Yarn to pull dependencies. Since this appears to compile some binaries, I wondered if my being on Alpine was complicating things (BusyBox builds tend to be a bit trickier). I have therefore swapped to Ubuntu. My Dockerfile is pretty simple:
