I tried to run the test in another machine and I get a different error:
> server@1.0.0 test /mnt/data/Desenvolvimento/workspace/mflix-js

Teardown Mongo Connection
Jest did not exit one second after the test run has completed.
Those are different Linux machines, where the version of the dependencies may differ (for example, in the first one I have the mongo client version 3.6 and in the second one version 4.2).
Update:
In this second machine, when I raise the connectTimeoutMS to, say, 20000, it works!
So, what could be wrong with the first one? There the error happens in the test/config/mongoEnvironment.js at the teardown() function. I’ ve seen posts here where people also have the same error, but I’m not sure what the solution is…
