Since you can deploy these with code, I'd assume you'd have a matching "test" serverless function that you treat as a black box and observe ins/outs. Of course, this means you're counting on things like connections configuration that changes between test and prod being done correctly.
Maybe there are emulators as well. If not, testing is certainly going to be hard.
