Here is a functioning example (source files attached, or download from


and run 'test.py', reproduced below):

import unittest
from doctest import DocTestSuite

### load doctests from another directory

import sys
sys.path.insert(0, 'other-directory')
import mod
doctest_suite = DocTestSuite(mod)


class MyTest(unittest.TestCase):
    def test_something(self):
        assert 1 == 1

if __name__ == '__main__':
    suite = unittest.TestLoader().loadTestsFromTestCase(MyTest)

    for t in doctest_suite:


I would like to be able to achieve this same effect without explicitly
creating a TestSuite and adding tests to it individually.  For example,
code like this would let me simply call 'unittest.main()' because the
doctest test cases would be recognized as unittest.TestCase objects:

import mod
doctest_suite = DocTestSuite(mod)
testcase_mimicking_doctest_suite = Wrapper(doctest_suite)

I suspect there's no good way to do this, but I thought I'd ask ;)
