Ok, then why would things get logged multiple times? The two test cases
actually test a loader function that I could strip out, because it wasn't
relevant. In these cases, the loader was being called with two different
configurations in the individual setUp methods.
I left them there to show that in LoaderTC, there is one debug log coming from
SimpleChecker, but in the NameSpaceTC, each debug message is printed twice. If
I print statements on each test_ method, they are called once.
As far as stripping down the code, I suppose 15 lines can be culled:
#---------
import logging
class SimpleChecker(object):
def __init__(self,):
self.logger = logging.getLogger(self.__class__.__name__)
h = logging.StreamHandler()
f = logging.Formatter("%(name)s - %(levelname)s - %(message)s")
h.setFormatter(f)
self.logger.addHandler(h)
def __call__(self, thing):
self.logger.debug('calling %s' % thing)
return thing in ['a','b','c']
import unittest
class LoaderTC(unittest.TestCase):
def setUp(self):
self.checker = SimpleChecker()
def tearDown(self):
del self.checker
def test_callable(self):
self.checker.logger.setLevel(logging.DEBUG)
self.assertTrue(self.checker('q') is False, "checker accepted bad
input")
class NameSpaceTC(unittest.TestCase):
def setUp(self):
self.checker = SimpleChecker()
def tearDown(self):
del self.checker
def test_callable(self):
print "testing callable"
self.checker.logger.setLevel(logging.DEBUG)
self.assertTrue(self.checker('a'), "checker did not accept good value")
self.assertFalse(self.checker('f'), "checker accepted bad value")
if __name__=='__main__':
unittest.main(verbosity=0)
#-----------
The output:
SimpleChecker - DEBUG - calling q
setting up NameSpace
testing callable
SimpleChecker - DEBUG - calling a
SimpleChecker - DEBUG - calling a
SimpleChecker - DEBUG - calling f
SimpleChecker - DEBUG - calling f
----------------------------------------------------------------------
Ran 2 tests in 0.014s
OK
Exit code: False
