In the specific case in question, the biggest problem was that dependencies like Zookeeper weren't compatible with our testing approach, so we couldn't do true end to end tests unless we replaced them. One of the nice things about Antithesis is that because our approach to deterministic simulation is at the whole system level, we can do it against real dependencies if you can install them.
