My apologies for posting here first, but I'm not yet confident enough in
my bug searching fu, and duplicates are a pain.
Here's the issue:
from unittest import *
class MyTest(TestCase):
def test_add(self):
self.assertEqual(1,(2-1),"Sample Subraction Test")
if __name__ == '__main__':
main()
I know this isn't the normal way to use unittest, but since __init__
goes to the trouble of defining __all__ I would think it was supported.
However, it doesn't work -- I added some print statements to show
where the problem lies (in unittest.loader.TestLoader.loadTestsFromModule):
----------------------------------------------------------------------
checking <class 'unittest.case.FunctionTestCase'>

checking <class '__main__.MyTest'>

test =

tests=[<unittest.case.FunctionTestCase tec=runTest>]>,
<unittest.suite.TestSuite tests=[<__main__.
MyTest testMethod=test_add>]>, <unittest.suite.TestSuite tests=[]>]>
---------------------------------------------------------------------
compared with running using the `import unittest` method:
---------------------------------------------------------------------
checking <class '__main__.MyTest'>
added
checking <module 'builtins' (built-in)>
checking None
checking None
checking 'test_add_right.py'
checking '__main__'
checking None
checking <module 'unittest' from 'C:\python32\lib\unittest\__init__.py'>
test =
<unittest.suite.TestSuite tests=[<unittest.suite.TestSuite
tests=[<__main__.MyTest testMethod=test_add>]>]>
---------------------------------------------------------------------
As you can see, the TestLoader is getting false positives from
case.FunctionTestCase and case.TestCase. This a problem because,
besides running more tests than it should, this happens:
E.

I'll be happy to file a bug report if someone can confirm this hasn't
already been filed.
Thanks for the help!

PS
No, that's not my code. ;)
