However, generally since it designed to be run in an ephemeral way, the testing process will be sending commands to the node to clear its data regularly. You'll likely need to use the debugger or some other blocking command to access the test server externally in a meaningful way. > Is it possible to persist a test server's data to a file, say, a JSON file, > and then load it on startup?

Test server's storage is completely in memory, and there's no sense of transactions so you can't roll back to a previous state. This means if you did go with "fixtures" strategy, they would need to be loaded at the beginning of every test/example. That could get quite expensive. As you would with a relational database, try to make your tests actually hit it as little as possible.
