Any Gemini client test suites?

I'm making some big changes to my Gemini client for Kindles and I'm looking for a client test suite to make sure I haven't broken anything. I remember there being a capsule containing a client stress test but the owner took it down because bots kept getting stuck. Are there any similar test suites online? Or even better, is there one I can run offline on a local Gemini server? Just though I'd ask before I write my own in case something like this already exists.

If you have any suggestions I'd love to hear them via email or a gemlog post.
