Ah this was an issue of rehabbing the test from integration to e2e as that was the more appropriate term
from testing-nestjs.
Ah, actually, no I see what happened. I removed it because it was being ran with the unit tests and it required the running of a database server. It should have been moved to its own directory with its own test command and jest config, like the e2e tests, I just didn't set that up at the time.
For reference, here was the file
/**

Ah, ok thanks! Yeah, that makes sense.
Regarding naming things, in our project we try to distinguish between integration tests and e2e test in such a way that the integration is testing e.g a service in its smallest possible environment, just like the cat.integration.spec.ts, where as e2e attempt to test the whole app from its public APIs and from the perspective of a user journey..
But I see it's common to call both e2e tests
from testing-nestjs.
