NASA mistakenly severs communication to Voyager 2

>>belter+(OP)
Does NASA have any sort of emulator to test commands against before they run them on live?

I mean, we're all human, I've made some really shitty fatal errors hacking untested code onto production servers.

It's hard to find anything about older programs, but they currently put a lot of work into simulators.

On the other hand, at one time there was a physical "proof test model" of the Voyagers.
