nose2 does separate collection from running and breaks backwards
compatibility with nose's generator tests. This can be pretty surprising in
some cases, if you're using generator tests in a test class and you expect
to be able to use instance attributes set in setUp in the generator
function -- you can't. That's currently filed as a bug against nose2, but
I'm coming around to thinking that it's just the way the design has to
work. So I guess that would be my opinion -- there's no need to preserve
compatibility with nose.
