interop test occasional fail?

[Jer Miller]

any ideas what might cause this to happen once in a while? is it my code? :)

I'm able to reproduce the error.

I'm also woking on an interop testing tool (that uses docker). https://github.com/fd/interoper
The tool will run test commands between any number of implementations cross-checking everything.

[Jer Miller]

Awesome news on the tool!

I haven't tried to diagnose this yet, but the (very untested/young) reliable channel support in telehash-c makes the go interop test stop:

It's probably the c code, but thought I'd post here just as an artifact as I dig into it :)

[Simon Menke]

@quartzjer I just push to interoper and I also moved it to the telehash org (hope that is okay).

I started documenting how interoper works (have a look at the README.md and the tests/ folder.

My goal is to support two modes.

• Dev mode for running tests while working on a specific implementation. this will run your implementation as an SUT and as driver against all other implementations.
• tournament mode for running all implementations against each other (again both as SUT and driver). This should also result in a interop report that can be published online.

I'm making good progress on the dev mode.

Some things that need discussion:

• tournament mode would ideally be run once a day (regardless of code changes). who will do this and where will this be done?
• all implementations must build and publish docker images which are specifically setup for the interop tool (this is not that hard but most CI systems don't support docker. except for Wercker and maybe some others. so there should be a simple way to update the images. again atleast once a day).

[Jer Miller]

Moving the interop testing to it's own repo is great! Let's close this issue here and I'll go add some thoughts in ones there now, thanks :)
