Public bug reported:
Binary package hint: python2.6
The following condition, on line 595 of unittest.py does not function
correctly:
elif isinstance(obj, TestSuite):
For whatever reason, when "obj" is in fact an instnance of a TestSuite
object, it is not detected as such. Worth noting - I have tested this
with the Ubuntu supplied python2.7 and the problem goes away. Here is a
simple test case:
#mytest.py
import unittest
class BasicTests(unittest.TestCase):
def runTest(self):
self.assertTrue(True)
suite = unittest.TestSuite()
suite.addTests([BasicTests()])
Run the above code from the command line:
> python -m unittest mytest.suite
You get an error like the following:
Traceback (most recent call last):
File "/usr/lib/python2.6/runpy.py", line 122, in _run_module_as_main

File "/usr/lib/python2.6/unittest.py", line 613, in loadTestsFromNames

File "/usr/lib/python2.6/unittest.py", line 598, in loadTestsFromName
test = obj()
File "/usr/lib/python2.6/unittest.py", line 464, in __call__
return self.run(*args, **kwds)
TypeError: run() takes exactly 2 arguments (1 given)
This is happening because the condition is failing, so execution is
falling through to the final "else" block, where it tries to execute the
TestSuite as a function:
elif isinstance(obj, TestSuite):
return obj
elif hasattr(obj, '__call__'):
test = obj() #EXCEPTION RAISED HERE
** Affects: python2.6 (Ubuntu)
