That’s the thing. People exposing such rude behavior usually are not, or haven’t been in a looong time…

As for the local testing part not being performed, this is a slippery slope I’m fighting everyday: more and more cloud based services and platforms are used to deploy software to run with specific shenanigans and running it locally requires some kind of deep craft and understanding. Vendor lock-in is coming back in style (e.g. Databricks)

Yeah, I get frustrated by cloud-only systems that don't have a good local testing story.

The best solution I have for that is staging environments, ideally including isolated-from-production environments you can run automated tests against.

Whenever I have to work with such systems, is usually when I do have to write an interface and have a mock implementation. Iteration is much faster when I don’t have to worry about getting the correct state from something I don’t have control over.
