I'd question the wisdom of checking into an integration server every couple
of minutes. I'm not sure if you meant that but if you did then I think these
sort of checkins have to be in bigger chunks. The reason is that each
checkin to an intergration server is asking my colleagues to checkout my
code and integrate it into their current work. So everything I check in to
the intergration server should be fit for them to use, and ideally it should
have been reviewed (self review, or even better a bit of peer review - easy
enought if pairing). You just can't do that in 2 minutes. IMO a complete
scenario is about the smallest size chunk to integrate with, and a complete
feature about the largest
Of course if your using Git (or any distributed vcs) you can just branch,
commit locally and rebase from the master. If you want to push to get a
backup as well, you can always have a backup target in addition to your
integration target. If your not using Git (or something similar) locally I'd
highly reccomend that.
I think its reasonable to make failing steps pending for an integration
commit, but its not something I would like to do regularly, much prefer to
wait a bit longer before integrating and make them green.
I really don't like working with more than 1 failing step, but find that
occasionally I end up doing that (normally because a new step prompts a
refactoring of and older step and that then breaks as well)
