You can either write a file-like object that uses Logger methods under the
hood or write your own test runner that uses Logger methods.
A basic example targeting Python 3:
$ cat log_unittest.py
import logging
import unittest
import os
logger = logging.getLogger()
class TestMyEnvClass (unittest.TestCase):
def setUp(self):
pass
def testMyEnv(self):
res = os.environ.get("res") == "1"
self.assertEqual(res, True, 'Testing my environment..')
def tearDown(self):
pass
class LogStream:
def __init__(self, logger):
self.logger = logger
def writeln(self, s=""):
self.logger.info(s)
def write(self, s):
self.logger.info(s)
def flush(self):
pass
class MyTextTestRunner(unittest.TextTestRunner):
def __init__(self, logger):
super().__init__(None)
self.stream = LogStream(logger)
if __name__ == "__main__":
logging.basicConfig(level=logging.INFO)
logging.info("hello world")
runner = MyTextTestRunner(logger)
unittest.main(testRunner=runner)
$ res=1 python3 log_unittest.py
INFO:root:hello world
INFO:root:.
INFO:root:
INFO:root:----------------------------------------------------------------------
INFO:root:Ran 1 test in 0.000s
INFO:root:
INFO:root:OK
INFO:root:
$ res=0 python3 log_unittest.py
INFO:root:hello world
INFO:root:F
INFO:root:
INFO:root:======================================================================
INFO:root:FAIL: testMyEnv (__main__.TestMyEnvClass)
INFO:root:----------------------------------------------------------------------
INFO:root:Traceback (most recent call last):
File "log_unittest.py", line 14, in testMyEnv
self.assertEqual(res, True, 'Testing my environment..')
AssertionError: False != True : Testing my environment..
INFO:root:----------------------------------------------------------------------
INFO:root:Ran 1 test in 0.001s
INFO:root:
INFO:root:FAILED
INFO:root: (failures=1)
If you want more control you have to rewrite more code ;)
