I found another example of nose not saying much, and this one is kind of 
annoying.  Unittest has much richer assertions, and better reporting 
when they fail.  If a nose assertion fails, you just get:

------------------------------------------------------------------
Traceback (most recent call last):
  File 
"/home/roy/production/python/lib/python2.6/site-packages/nose/case.py", 
line 197, in runTest
    self.test(*self.arg)
  File "/home/roy/songza/pyza/djapi/test_middleware.py", line 48, in 
test_update_non_json_cookie
    assert user_list == [9990]
AssertionError
------------------------------------------------------------------

Under unittest, it would have printed the value of user_list.  Yeah, I 
know, I can stick a "print user_list" statement into the test, and the 
output will get suppressed if the test fails.  But that means when a 
test fails, I need to go back and edit the test code, which is a pain.

On the other hand, there *is* an incremental efficiency gain of writing:

assert x == y

instead of

assertEqual(x, y)

many times.  So maybe overall it's a wash.
