Honestly, just pinging won’t cut it. You gotta simulate real usage. I use Scraper API (paid but worth it) to test proxy servers cuz it auto-rotates and gives stats on uptime.
For free options, httpbin.org/ip is clutch—it shows if the proxy’s working and what IP it’s using.
And yeah, anonymity checks are a must. DNS leak tests are your friend. If you’re paranoid, run a WHOIS lookup on the proxy IP to see if it’s flagged.
