LoRaWAN® Certification Test Tool or Protocol tester?

Out of curiosity, does anyone here have access to the LoRaWAN® Certification Test Tool (LCTT)? Or a lorawan protocol tester or similar?

I’m considering spending the time to merge the Heltec changes with the LoraMac-node 4.4.3/4.4.4 code. The current loramac code appears to have been forked off the LoRaMac code in early 2018 and had selected changes merged back, and some Alibaba contributions, since then.

It would be good to be able to fully test the code too see if it’s anywhere near correct after doing that work. Especially as I only have a personal interest in getting AS923 working and have no gateways to test the other bands.
