Build four fixture libraries that export objc_getClass, sel_registerName, objc_msgSend and the autorelease pool functions (complete, without NSProcessInfo, returning no activity, without pool functions) and drive the backend through them on any POSIX host. Check the exact message sequence (begin with the user-initiated and latency-critical options, retain, end, release), balanced pools on every path, a held activity ended by the destructor, and unavailable and refused results.
