Salva commented on FLINK-26845:
-------------------------------
Are there any short-term plans for addressing this issue [~sjwiesman]
[~trohrmann]? A first step would be to give some general guidelines based on
the current state of the project (i.e., without requiring adding new
testing-specific features/utilities). The documentation/examples should cover
the following:
- How to do simple unit tests of your functions? In particular, do the
different language sdks already provide mocks for the context? This is probably
the only thing statefun-specific unless I'm missing something.
- How to do e2e of your entire functions mesh? There might not be anything
statefun-specific here though, in that case the docs could simply point that
out (and optionally point readers to an example).

> As of now, there seems to be not much guidance on how to approach testing.

> I think that at the very least testing should be mentioned as part of the
> docs, even if it is only to stress the above fact. Indeed, as reported by

> on that front
> {quote}Testing tools is definitely one area where we want to improve

> updated. There are some testing utils that you can already use today:
