35322	Slow feedback loop in tests using Postgres	Martin Lehoux	nobody	"I have a growing codebase, and the tests are getting slower and slower. My main concern is when iterating on a small test case, the overhead of running tests is the largest part of the runtime (as opposed to running all tests in continuous integration). I am running tests with pytest-django, my database is a postgres running in a docker-compose.

My baseline was 20sec with --keedp-db. I made some improvements that were easily accessible : --no-migration gave me a 3sec improvement.

But while digging into the code, it seems that whatever options I provide, I cannot skip the `call_command(""migrate"" ...)` part. I wonder why this is the case, because commenting this part gave me a 5.5 sec improvement.

I must say my django startup time has risen up a lot, at around 5 sec.

Is there something I'm missing about running small tests?"	Uncategorized	closed	Uncategorized	5.0	Normal	invalid			Unreviewed	0	0	0	0	0	0
