Is there a way to do your testing without a gui? I have no idea what your testing setup requires, but is there some technical reason why tests are not done automatically in your ci/cd pipeline?
If it must be done manually, can you just ssh/rdp directly into the testing box? The network where the testing box exists could use some tunneling protocol (stunnel, socks, wireguard, vpc peering...) to make it more accessible from your dev machine or your company VPN.
