I have previously advocated a library interface as a detailed
testsuite interface (in addition to a lowest common denominator
interface of stdio+exitcode). That is a test stanza in a package
.cabal file would specify a module containing an entry point of the
right type (like main but using a more interesting type).

That way, cabal or any other tool could run the testsuite and produce
results in whatever format it likes.

As you suggest in your other post, it would make sense to adapt
test-framework to implement the interface specified by Cabal.
