    # equivalent to the persistent state). While this works for most of the
    # tests in this class, that would prevent us from testing things like
    # "run a command that is expected to fail, and then ensure nothing
    # happened", because we'd be asserting in `load_persistent_db()` due to
    # the map being empty.
    #
    # This function will therefore force state to be written to our mock
    # persistent state. We could have added this extra step to
    # `load_persistent_db()` directly, but that would conflict with the
    # upgrade tests. This way, we can selectively enforce this requirement
    # where we believe it to be necessary; generically speaking, this should
    # not be needed unless we're testing very specific behaviors.
