They can be a bit of a pain, but if you have a lot of logic tied up in your external dependencies (SQL usually bring main offender here) it's not possible to properly test without using said dependency.

That said, in the current job, we have a dedicated Postgres container that comes up with with a just file command. The setup, test, and teardown of schema all happen within the standard test system of the tested platform (pytest or go test specifically).
