nose, doctest, and module names in subpackages

I'm trying to use both nosetests and doctest with the tests
pulled out into a separate file. My problem is that it
seems that I need to use different import statements
depending on from where I run the tests.

Here's my directory structure:
/dir
__init__.py
/sub
__init__.py
code_file.py
test_code_file. py
tests.txt

--- code_file.py: ---
def example_functio n():
return 0

--- test_code_file. py ---
def run_tests():
import doctest
result=doctest. testfile("tests .txt")
assert result[0] == 0

if __name__ == "__main__":
run_tests()

--- tests.txt ---
>>from code_file import example_functio n
With this, nosetests works when run from /dir/sub, but
the import fails if nosetests is run from /dir.

If I change tests.txt to

--- tests.txt ---
>>from sub.code_file import example_functio n
(adding "sub.") then nosetests works from /dir, but not
from /dir/sub. And in this case "python test_code_file. py"
fails when run from /dir/sub.

In general, I would like to run doctests during development
from the directory where the code lives, leading me to
prefer "from code_file import", but I would like to run
nosetests from the top of the tree, leading me to want
"from sub.code_file import".

I played around with variations like using doctest.DocFile Suite
and nosetests' --with-doctest option, but nothing I tried
helped with the basic issue of the name of the module
varying depending on the execution directory.

It seems I'm missing something very basic here. Any tips
would be much appreciated.

(I'm running python 2.4.1 and nosetests 0.9.0)

I have a problem writing self-testable modules using doctest when these modules have internationalized strings using gettext _('...'). - The main module of an application (say app.py) calls gettext.install() to install the special _ function inside Python builtin. Other modules, taken from a general purpose collection of Python modules, also support internationalisation and doctest testing. For example:

For writing testcode, it looks like there's three ways that it's typically done: (1). using the doctest module, (2). using the unittest module (i.e. "pyunit"), or else (3). just putting an "if __name__ = '__main__':" at the bottom of your module containing code to manually run your class through its paces.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
