nosetest w/o exit=False funks up in ipython about nitime HOT 5 CLOSED

How old an ipython is this on? On 0.10.1-0.11 we've been ignoring sys.exit(False) calls precisely for this reason...

SystemExit: False

Yes, but the traceback isn't printed by default, you need to request it with %tb. The idea is that in most cases, SystemExit isn't really an error for which you really want to see the tb, so we hide it.

The point of having that sys.exit happen is to set the proper exit code from the test process, so that any utilities (say a makefile) that run the test suite via

python -c "import nitime;nitime.test()"

can know if it succeeded or not.

Gotcha. So we can leave this as is and close this issue?

I think so, because those OS status codes are indeed valuable, even if
they cause a bit of noise in ipython (though as you see, much less in
current versions).
