Enhance error prompt while running go fn app locally about fdk-go HOT 4 OPEN

Hi and welcome! Here's the thing. You actually allocated problematic area very explicitly, however, it not related to fdk-go.
If you'd like to test your function, you need to use the following commands:

fn test

or

fn run

Because the format env var is not the only var you'd need to set (there are at least 6 to 10 env vars FDK would need).

So, the thing you've done is not typic or even recommended path go. I recommend you to spend some time playing with interactive tutorial here: https://www.katacoda.com/fnproject/scenarios/fn-intro

from fdk-go.

I did fn test and fn run and it behaves normally. I am just wondering how to test the function locally, as you said it is not recommended. I got it. Thanks.

Well. There have to be 2 ways to test your function:

• fn test with a bunch of test suites
• go test fixtures like FDK-java has (an extension to a native unit tests)

So, FDK-go misses the 2nd point. I'd better rename this issue to something in lines to:

Provide Go native testing framework for functions for sake of better coverage

from fdk-go.

Sure, agree.
