It's not even about faster computers and storage, but just about better test techniques, and better written tests. You don't actually need very fast hardware for fast tests; you just need to spend some time on it. And roughly know what you're doing.

External dependencies (such as PostgreSQL, Redis, what-have-you) are a pain though. I feel pretty strongly that just a single command ("go test", "cargo test", "npm test", etc.) should run all the tests on all platforms, reliably, with a minimal of fuss and messing about. Things like docker-compose or whatnot quality as "a fuss and messing about".

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).
