Slightly different approach, but appears to have the same overarching goals: https://github.com/bullet-train-co/magic_test

„Magic Test allows you to write Rails system tests interactively through a combination of trial-and-error in a debugger session and also just simple clicking around in the application being tested, all without the slowness of constantly restarting the testing environment.“

I will keep an eye on both now, probably they will compliment each other at some point in time.
