Logging within py.test tests

I would like to put some logging statements within test function to examine some state variables.

I have the following code snippet:

import pytest,os
import logging

logging.basicConfig(level=logging.DEBUG)
mylogger = logging.getLogger()

#############################################################################

def setup_module(module):
    ''' Setup for the entire module '''
    mylogger.info('Inside Setup')
    # Do the actual setup stuff here
    pass

def setup_function(func):
    ''' Setup for test functions '''
    if func == test_one:
        mylogger.info(' Hurray !!')

def test_one():
    ''' Test One '''
    mylogger.info('Inside Test 1')
    #assert 0 == 1
    pass

def test_two():
    ''' Test Two '''
    mylogger.info('Inside Test 2')
    pass

if __name__ == '__main__':
    mylogger.info(' About to start the tests ')

    pytest.main(args=[os.path.abspath(__file__)])

    mylogger.info(' Done executing the tests ')

I get the following output:

[bmaryada-mbp:/Users/bmaryada/dev/platform/main/proto/tests/tpch $]python minitest.py
INFO:root: About to start the tests 
======================================================== test session starts =========================================================

collected 2 items 

minitest.py ..

====================================================== 2 passed in 0.01 seconds ======================================================
INFO:root: Done executing the tests 

Notice that only the logging messages from the '__name__ == __main__' block get transmitted to the console.

Is there a way to force pytest to emit logging to console from test methods as well?
