Okay, I see now.

However, is it not better to have even a limited test than none at all?
Granted, we still would not know whether rebased commits would be signed
properly. But if my trivial test case fails, we would still have a strong
indicator that something is broken, with a very convenient way to debug
it. And that is what a regression test suite is all about, isn't it?

Of course I agree that it would be very nice to have a test at a later
stage that does exercise GPG if it is available. But would it really be so
terrible to have a (simpler, not as complete) test that is exercised
*also* when GPG is *not* available?

Ciao,
Dscho
