What is the best way to test a cast action under development?

for my frames - frames.js has a test environment built in.  

outside of that, when i move it my prod environment - before i announce anything, i test it here: https://warpcast.com/~/developers/frames, install it and validate it works as designed.

yes, it might not run with your requirements .  i have them embedded into my frames, so when they're installed, they function the same way

fyi - here's the dev environment for frames.js where i test the cast action.

that's for a frame, but what about a cast action?
