There was a typo in the .env file, however that bug fix did not solve the issue

-MAILER_FROM="Test mail" <someusername@denrox.com>
+MAILER_FROM="Test mail <someusername@denrox.com>"

Hi, thank you for the report! Please confirm that before running tests command you executed steps:

• cp .env.example .env && cp .env.test.example .env.test
• docker-compose -f ./docker-compose.test.yml up -d

If yes, then could you please leave a comment here with the results of command "docker ps -a"
You should have a mongo container up and running with hostname "db" and the port number "27017"

It looks like the user was not created

Hi,
I suggest you to apply a temporary fix for this issue

Please add a record
127.0.0.1 db
To the /etc/hosts file on your machine

To get rid of previously created containers with errors, pls run docker rm -f $(docker ps -aq | grep "nestjs")

After this you can rerun steps for running tests.

This is kind of a temporary spike. But I will introduce a proper fix via docker networking on next update
