[Bug?] [Mongoose/Mocha] Not connecting to database

[piotrryczek]

Hello,
I've spent couple (4-5) hours trying to make it works but it looks like it is something above me.

Error:
UnhandledPromiseRejectionWarning: MongoNetworkError: failed to connect to server [localhost:27017] on first connect [MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017]

Getting error for any settings configuration.

Here is repo:
https://github.com/piotrryczek/test-actions

Actions:
https://github.com/piotrryczek/test-actions/actions

Workflow:
https://github.com/piotrryczek/test-actions/blob/master/.github/workflows/main.yml

Here is sample test:
https://github.com/piotrryczek/test-actions/blob/master/src/models/___tests__/sample.test.ts

As you see I tried both via app and via mongoose standalone connection.
Env is correctly being injected.

Before also trying with Jest.
Locally tests are working correctly.
It is definetly problem with mongoose connection to mongo database.

Thank you in advance!

Didn't set a replica in mongoose connection settings...
