Are you aware of our black box tests in bzrlib.tests.blackbox.test_*?
Comprehensive tests for all our command-layer handling lives there
currently.

From your description of your tests they will be extremely fragile to
changes in any defaults: E.g. the transition from knits to packs would
have changed the output data radically. Fork+exec is also slow when done
thousands of times, which is why we only fork & exec sufficient to test
that the test harness is robust and beyond that do it all in-process.

That said though, what sort of coverage would the thing you have put
together *add* to our current testing?
