Because functions are small self-contained stateless bits of code, they don't need much testing by themselves.

You need to test them with the services they are using and replicating your whole cloud infrastructure locally is nearly impossible.

Maybe they'll tell me I'm wrong, but Netlify strikes me as not targeting people who need a "whole cloud infrastructure" (since they don't offer many services), but a static site with a few simple backend functions.

Cloud be, yes.
