Somebody has to test and debug your app on actual PPC hardware.

Our Xcode-supported unit tests transparently run three times -- once for x86_32, once for x86_64, and once for PPC. The PPC run occurs within Rosetta (ie, emulated).

If the tests pass, we can be reasonably sure everything is A-OK. In addition, we can do local regression testing under Rosetta (but it's rarely necessary -- usually everything just works).

The only native PPC testing we do is integration testing once we reach the end of the development cycle.
