I am using nosetests test.py
to run unit tests:
import unittest
import logging
class Test(unittest.TestCase):
def test_pass(self):
logging.getLogger('do_not_want').info('HIDE THIS')
logging.getLogger('test').info('TEST PASS')
self.assertEqual(True, True)
def test_fail(self):
logging.getLogger('do_not_want').info('HIDE THIS')
logging.getLogger('test').info('TEST FAIL')
self.assertEqual(True, False)
When test fails, it prints out all logging info. I can use --logging-filter
to filer out only some loggers:
nosetests test.py --verbosity=2 --logging-filter=test
test_fail (test.Test) ... FAIL
test_pass (test.Test) ... ok
======================================================================
FAIL: test_fail (test.Test)
----------------------------------------------------------------------
Traceback (most recent call last):
File ".../test.py", line 14, in test_fail
self.assertEqual(True, False)
AssertionError: True != False
-------------------- >> begin captured logging << --------------------
test: INFO: TEST FAIL
--------------------- >> end captured logging << ---------------------
----------------------------------------------------------------------
Ran 2 tests in 0.001s
FAILED (failures=1)
However, it does not show anything when tests pass.
I would like to see output of one specific logger when tests pass. I have found that I can use -s
to show all stdout / stderr text which is not exactly what I need - it prints everything. I tried to play with various settings such as --nologcapture
, --nocapture
, or --logging-filter
but I was not able to get desired effect.
nosetests --help
does not make this obvious AT ALL, but the answer is the --debug
flag. This flag takes as an argument the name of the logger that you'd like to receive messages from.
Here's a slightly modified version of the OP's code:
# test.py
import unittest
import logging
class Test(unittest.TestCase):
def test_pass(self):
logging.getLogger('hide.this').info('HIDE THIS')
logging.getLogger('show.this').info('TEST PASS')
self.assertEqual(True, True)
def test_fail(self):
logging.getLogger('hide.this').info('HIDE THIS')
logging.getLogger('show.this').info('TEST FAIL')
self.assertEqual(True, False)
For this example, nosetests test.py --debug=show.this
should do the trick.
