A good start might be to validate STUN and TURN functionality - and there are much smaller libraries for both of those protocols.
The other test worth having in place is seeing if a DTLS connection can be established - probably to a backend infrastructure node participating in the experiment.
I agree, STUN and TURN are probably the best place to start.
I did a cursory search to see if there are any public DTLS servers (thinking that OONI could test connections to them), but didn't find any. However I did find that some Internet-of-things standards (LWM2M and oneM2M) use DTLS. https://en.wikipedia.org/wiki/OMA_LWM2M
