Sylvain Lebresne commented on CASSANDRA-11126:
----------------------------------------------
bq. I'm afraid this isn't possible with ccm as it is
Well, {{ccm}} certainly support running from a local directory so it ought to
be possible. But I think I see what you mean, and I agree we can fix {{ccm}} so
it's much easier to make this work transparently for this kind of test. We
definitely should do that though.
bq. The way I recommend you test two particular branches is to push them to
GitHub
I'll do it this time, but that's seriously painful, as a typical way to debug
such a problem involve multiple change/recompilation and having to commit and
push every time adds significant annoyance and slowness to the process (if for
no other reason than because I assume {{ccm}} will do a clean before
recompiling every time which I can avoid most of the time locally).
Anyway my main point being, when you work on this type of test framework,
please keep in mind that having an easy way to test against a local checkout is
pretty important for us, devs.
