Testing models with SQLAchemy 0.4

[iortega]

I'm following the tutorial 'SQLAlchemy 0.4 for people in a hurry'. I
could configure sqlalchemy but when I tried to run nosetes this error
arises:

E

How I can fix this error?

Thanks.

Assuming you're running Pylons 0.9.6.1, add the following block to your setup.cfg:

[nosetests]

verbose=True

verbosity=2

with-pylons=test.ini

detailed-errors=1

with-doctest=False

Then run (this won't be needed in the next release):

sudo python setup.py develop

And you can now run nosetests like so:

python setup.py nosetests

I've updated the doc here to reflect this as well:

Cheers,

Yes, I'm running Pylons 0.9.6.1.
Your solution works!!!
Thanks!!!

Yes, that works for me too.

Why do you have to python setup.py develop and what does that do?

If I don't do that I get a traceback like this:
global_conf=global_conf)

As far as I know, "python setup.py develop" registers the current project in
Python's 3rd parte repository (In windows normally is c:\python25\lib\site-packages),
creating a file named [your module].egg-link. In this file is stored the base path of your project.
When this file is created,  python  now can  find  your project when you import modules like
"import [your module].tests.mytest"

It also makes sure the package's dependencies are installed, including
any indirect dependencies. "simpleauth" is apparently a dependency,
probably provided by another package.

If you change your package's dependencies (i.e., by editing setup.py),
running "python setup.py develop" again will bring your system up to
date.
