Okay, I uncommented those two lines and got:

E:\Projects\mcm>py -m unittest ./mcm/test/db/test_manager.py
Traceback (most recent call last):
  File "C:\Python34\lib\runpy.py", line 170, in _run_module_as_main

    module = __import__('.'.join(parts_copy))
ValueError: Empty module name

Now what?

Scratching my sleepy head...
