We've just open sourced the API that powers our Browser Privacy Test Tool, written in Golang: https://github.com/tenta-browser/nsnitch.

As you know, many of the best VPNs today offer a secure DNS solution, but just testing for IP, ISP, hostname and geolocation isn't enough. For example, the Nsnitch API checks if DNS over TLS is enabled. This is a relatively new protocol, but an increasingly important setting that actually keeps your DNS requests encrypted/private. You can also see if DNSSEC is enabled or "Checking Disabled" is on or off. Overall, these results give you a more complete picture of your DNS privacy and security settings.
