I created a DocTest file for the actual module I want to test and weirdly I don't get the import issue... I don't see any difference except the module I'm testing is two folder layers deep (.../Apps/AppName/appname.py rather than .../HelloWorld/helloworld.py). But as it's fully working with the module I actually want to test, that's fine for me for now.

Thanks JonB. The testing of the get_hello function works. However the test fails on the line of the import helloworld. It says Got: (the info of sys.path). This does not stop me testing my code now, however it just has one failure due to this. Any thoughts? Thanks again.

>>> import sys; _path = '/private/var/mobile/Containers/Shared/AppGroup/.../Pythonista3/Documents/HelloWorld'; sys.path.append(_path)


>>> import helloworld
>>> helloworld.get_hello("Richard")
'Hello Richard'

Hi, I'm having issues getting the DocTests to run as a seperate file using the built in DocTests feature (creating a file name.doctest file and pressing play). The DocTest file works when calling existing packages, but if I do the following:
New top-level folder called "HelloWorld"
New script called "helloworld.py" with the following code:

def get_hello(name):
    return "Hello " + name

Then create a "helloworld.doctest" with the following:

>>> import helloworld
>>> helloworld.get_hello("Richard")
'Hello Richard'

Then run the DocTest by pressing play (pressing play using the default template passes), I get the following error:

ImportError: No module named 'helloworld'
NameError: name 'helloworld' is not defined

If I add the DocTest into the comment of the method, running DocTest works on that script. But I want to remove clutter and have the tests in a seperate file and use this feature.

def get_hello(name):
    """
    >>> get_hello("Richard")
    'Hello Richard'
    """
    return "Hello " + name

Is there something I'm missing? Any help will be most appreciated
