Means to force export

[garthk]

:timer.sleep/1 in tests makes babies cry; any chance of an exported method to trigger export so we can verify the exporter worked?

With elixir if you can turn the export into a message (I'm assuming this is for honeycomb so you can't just use the _pid exporter?) and do assert_receive which takes a timeout.

In opentelemetry tests we are using a macro to do the same as assert_receive and in the case of testing zipkin and otel protocol I just manually call their export functions.

Definitely could use better testing on the zipkin/otpl side as it just verifies its an "ok" :):

?assertMatch(ok, opentelemetry_zipkin:export(Tid, Resource, State)),

Yeah, a receive was how I ended up doing it. It's replacing one timeout Sean didn't like with another he shouldn't, but not to worry :)
