I have many many many python unit test, which are used for testing
some remote web service.
Part of your confusion comes from the fact that "test a remote
service" isn't what a unit test does.
A unit test is one that executes a very *limited* part of the code: it
tests a code unit, not the whole system, and makes a simple set of
assertions about the result. If there are accesses to remote services
over the network, that's far beyond the scope of a unit test.
I don't doubt that you may be using the Python standard library module
'unittest' to perform these tests. But they're not unit tests; they're
integration tests, or system tests, or performance tests, or something
else.
Can someone explain my why so simple feature like logging of
timestamps during test execution was not implemented in any
extension?
Probably because the most important thing to know for the purpose of a
unit test is whether the yes/no assertions were violated. Knowing when
the tests start and finish isn't interesting. If start and finish
times *are* interesting for your tests, you're *not* doing unit
testing, but some other form of testing like performance tests.
That said, you *can* certainly instrument the unittest.TestCa se with
timings if you want to use it for a performance test. Every instance
of a TestCase will invoke its setUp method to set up test fixtures,
and its tearDown method to tear down fixtures. You can use that hook
to implement logging.
Untested code, that should give you enough to try it out yourself:
import unittest
import logging
logging.basicCo nfig(level=logg ing.INFO,
datefmt="%Y-%m-%d %H:%M:%S",
format="%(ascti me)s:%(levelnam e)s:%(message)s ")
class TimedTestCase(u nittest.TestCas e):
""" A test case that will log its start and end times """
def setUp(self):
""" Set up test fixtures """
logging.info("t est case setup")
def tearDown(self):
""" Tear down test fixtures """
logging.info("t est case teardown")
class Test_FooBar(Tim edTestCase):
""" Test cases for FooBar """
def test_slices_spa m(self):
""" FooBar should slice spam """
self.failUnless (sends_spam)
def test_eats_eggs( self):
""" FooBar should eat eggs """
self.failUnless (eats_eggs)
