Hey @cv65kr 👋🏻

It would be nice to have tests for the new otel functionality (grpc and temporal). You may use a stderr collector and redirect the stderr in the buffer like I did here link. And then check for some otel-specific fields in the output.

Fair point about naming - done.

Yep, will write some tests.
