>My go-to strategy has been blackbox (comparison) testing. Capture as much input & output as I can. Then use automation to diff output.
Same here - you have an oracle, it would be a waste not to use it. You can probably also think of some test cases that are not likely to show up often in the live data, but I would contend that until you know the implementation thoroughly, you are more likely to find input that tests significant corner cases in the live data, rather than by analysis.
