What a pain it can be to reproduce issues for developers. How handy would it be if we could compile tests into an exe and pass it on for script playback? No easy request I'm sure, but I can dream...r...
As a non-Smartbear option you could possibly use something like Docker:
https://www.docker.com/what-docker
https://docs.docker.com/engine/installation/windows/
Though it might be a bit overkill.
Or perhaps Smartbear could make it easier for us to use Docker for this purpose? Or something similar?
