OpenAPI TTCN code generation? [message #1819286]

Dear Eclipse TITAN community,

like probably many others I'm currently wondering what the TITAN approach to testing the 5G Core SBA will look like. I suppose the HTTP2 support that was implemented and presented here in the forum some months ago was a first step in that direction, and not a coincidence?

The next step then is how to work with the Service/API definitions provided by 3GPP in OpenAPI 3 syntax. I've seen code generation for many different programming languages, including e.g. Erlang. But I haven't yet seen anything related to TTCN3.

Is there already some plan / roadmap / implementation? If so, will it be open source?

Note: I'm not demanding anything, I'm merely asking if there are plans or ongoing work in order to determine if TITAN can be used for testing 5G SBA without having to spend tons of time on implementing tooling first.

Thanks,
Harald

Hi Harald,

How to convert JSON into TTCN-3

that adds some detail to the JSON /TTCN-3 conversion.

Scripted support for TTCN-3 code generation from YAML or JSON is not available currently, but in my opinion it should not be a large investment;
however we could not find the justification to implement it due to the simplicity of manual conversion.

Best regards
Elemer
