问题
I'm contributing to a Python 3 project from a Windows 7 computer.
In order to minimise clutter while making and testing changes, I'm placing a few test files inside a folder called ignore within the project, and excluding it from the version control system (Git).
There is no __init__.py file in the root of the project, so I thought I'd create a symbolic link from the module I want to test into the ignore folder, to enable me to import it.
mklink ignore\example.py example.py
When I try to import the module from a script in ignore I get an ImportError saying the example module doesn't exist.
Is it possible to import modules via symbolic links in this way? I understand that this is supposed to work, but I can't find a reference saying that it works on Windows.

I have just spent +2 hours trying to resolve this issue and it turned out that creating a Windows Directory Junction worked for me.
You don't need to use a relative one, it worked with both.
So first create an empty file __init__.py in your igonore-folder
then in the elevated mode (As Administrator) create a link:
mklink /J ignore path-to-your-ignore-module
Then in your Python code you would be able to execute:
from ignore.something import some-other-thing
