Comment 7 for bug 625597

vila, I have https://code.launchpad.net/~mbp/bzr/test-errors/+merge/64485 towards this but it's not landed yet.

istr some discussion about wanting an option to get the tracebacks only at the end, but I don't really see a reason you'd want that, and nobody I spoke to said they do want it. So I think I will just print them as they occur; there's always subunit if you want more detailed output.
