Formatter for "Message" format NDJSON

[Johnlon]

Are there plans to create an output format for the Envelope data type as described here
https://github.com/cucumber/messages

I need compatbility with cucumber "message" format and the ability to reuse things like the cucumber-js report formats.

Currently, there exists no development effort to support such a formatter.
This may change in the future.

REASONS:

• In cucumber, Cucumber Messages are used as internal protocol between different parts of the framework implementation (as it needs a modular internal structure).
• behave has currently no such needs (except: You want to use Cucumber Reports ).

OTHERWISE:

• Formatters are an extension point in behave. Therefore, you can provide your own Formatter classes and use it in behave.
• If it is important for you, provide a pull-request with its Formatter implementation.

SEE ALSO:

• features/formatter.user_defined.feature
• https://reports.cucumber.io/

Seems a pity that cuke is using Message as the integration format now, but behave using something else as it makes interop/reuse impossible. Seems a common format means ability to have common tooling and the old cuke JSON format isn't that anymore. Cheers

• cucumber has its reasons why it does that and
• behave has its reasons why it does not do it, too (unnecessary overhead, unneeded complexity)

As already stated: If Cucumber Messages are important for you, provide a pull-request for such a Formatter (or provide your own). Otherwise, wait until it is supported in behave (but then it is not important for you IMHO).

I am currently adding ndjson support to godog using the cucumber compatibility kit.

As you stated that reason for wanting same on behave is to be able to reuse the widest variety of tools around my tests.
