Python 2.6: proper usage of unittest.TestSuite

Question

Using Python 2.6, I have a very simple test in a python file in a directory:

#mytest.py
import unittest

class BasicTests(unittest.TestCase):
    def test_ok         


        

Answer 1

I don't usually work with unittest on the command line, but have my own test running scripts.

You need to add a function suite to the module

def suite():
    return unittest.TestLoader().loadTestsFromTestCase(BasicTests)

and then call it like python -m unittest mytest.suite. But then I run into the following problem:

TypeError: calling  returned ]>, not a test

which happens because unittest uses something like isinstance(mytest.suite(), TestSuite) but through executing with -m, you get two different versions of the TestSuite class (one is __main__.TestSuite, the other is unittest.TestSuite), so isinstance returns false.
To me, this looks like a bug. Patching unittest.py by inserting from unittest import TestSuite, TestCase at the beginning of loadTestsFromName solves the isinstance problem. Sorry I can't give you the "correct" solution (if there is one).
