Along those same lines I've heard in a presentation once to start testing from the log entries. You could even take the log entries generated by your smoke test which report parameters and results.

Yes, this is a very good point. If you really must write tests for
your existing code, start with some high-level 'happy path' tests of
the flow of your external user interface. This can avoid the catch-22
of lower-level unit tests forcing you to refactor when you don't have
any tests to catch bugs.
