I've had this happen before, and it turned out to be a state problem.
Things I did in one spec file were altering the state of the
application, so that spec files run after it would fail in certain
ways.  Thus, passing or failing was entirely dependent on the *order*
the files were run in.  Rake runs things in a different order than
autotest, so different tests were failing; and running a single file
by itself always passed.

In my case the state change was stupid and totally unnecessary.  At
the time I didn't really understand mocking and stubbing, so I was
trying to bypass my authentication code in my specs by reopening the
authentication modules in lib/ and overriding the live logged_in?
method to return 'true'.  This worked, but I didn't realize the
overrides would continue to be in place for all future specs.  And
quite naturally, some of the specs for restful_authentication were

I wasted hours figuring that one out.  The moral I learned was, don't
EVER try to screw with your actual application code in a spec, and
make sure that nothing you do in a spec leaves a permanent change in
memory.  I can't know if that's your problem, of course, but it's
something to think about.

Have Fun,
