AttributeError: 'ContextSuite' has no attribute 'capturedOutput' in 0.10.3 #296

I came across the following issue with our custom output plugin for nose
when an Exception occurred when running setUp in a nose context suite:

AttributeError: 'ContextSuite' object has no attribute 'capturedOutput'

The attached patch fixed that issue, but it's odd why a ContextSuite is
being misinterpreted at this level...

0.10.3 is a very old version. Can you verify that this bug still exists in the
current code in mercurial?

AttributeError: 'ContextSuite' object has no attribute 'capturedOutput'

We were getting the same error when using the teamcity-nose and 
teamcity-messages plugin. Using Python 2.6. Tested with the latest nose 1.0.0 
on pypi, and tip at https://bitbucket.org/jpellerin/nose/ changeset 780: 
6318b0c855a6
Get the error on both.

Fixed it a little differently than yanegomi. Patch attached. The code will 
still pass through the error data to the teamcity plugin, so that the error 
gets printed in the teamcity service message, and you will know what failed. 
nat_linden kindly made a fork from nose tip, with the patch here: 
https://bitbucket.org/nat_linden/nose/

thanks
automated.test.spider and nat_linden

whoops, this issue wasn't tagged with the patch so we lost track of it.  Thanks 
for updating the patch.

If you can add a test that reproduces the error then it would greatly speed up 
getting the patch applied.  There is info in DEVELOPERS.txt for how to run the 
tests.

Thanks Kumar. I believe the issue occurs when you have a nose plugin using the 
old plugin api (0.9) which goes through the ZeroNinePlugin code.  The test 
script has a setup function, rather than a method of a unittest.TestCase 
subclass. If there is a failure during the setup function, the test object has 
no capturedOutput attribute, nor does it have a test attribute (test.test). 
I'll work on making a unit test case that simulates this condition.

If useful, here are some manual steps to reproduce:
1) Create a virtualenv
virtualenv --no-site-packages --distribute issue296
2) Pip install the teamcity-nose package, which will install the 
teamcity-messages dependency, and nose. The TeamCity plugin is based on the 
older nose plugin api.
issue296\Scripts\pip install teamcity-nose
3) I like to install and run yolk in my virtualenv, to verify the packages and 
their versions (but this is not required for the test)
issue296\Scripts\pip install yolk
issue296\Scripts\yolk -l
4) Make sure that the TEAMCITY_PROJECT_NAME environment variable is set with 
some value (any value). The teamcity-nose plugin checks for the environment 
variable to determine whether it should be active.
SET TEAMCITY_PROJECT_NAME=foo
5) Create a python script with test case functions that have a setup function 
that will fail. The setup and test case functions are NOT subclasses of 
unittest.TestCase. I named it break.py.
# Test cases which are not subclasses of unittest.TestCase
# with a setup function which will raise an Exception 
-----------------------------------
def setup():
    raise RuntimeError('break setup')

def test_one():
    print "testone"

def test_two():
    print "testtwo"
---------------------------------
6) Run the test script file via nosetests without -s.
