coverage.py and setup.py and Django testing

Question

I have a Django project with setup.py which looks like this:

.
├── backend
├── backoffice
├── backoffice_set
├── manage.py
├── MANIFEST.in
├── media
├── README.rst
├── requirements.txt
├── setup.py
└── venv2.7

When I run: python setup.py test everything is O.K.. However, when I run :

/opt/bin/coverage run setup.py test

The tests fail with:

writing dependency_links to cfe_backoffice.egg-info/dependency_links.txt
reading manifest template 'MANIFEST.in'
warning: no files found matching '*' under directory 'backoffice/templates/backoffice/'
writing manifest file 'cfe_backoffice.egg-info/SOURCES.txt'

Has anyone seen this before? Can you suggest a solution?

Answer 1

Well, after a while I found the solution. Django was not installed globally, which is what I wanted.

I created my virtual environment with:

 virtualenv --enable-system-packages

So this lead to coverage.py not being installed inside my virtualenv. Hence the solution, which was to force pip to install it with -I, here is the full log of actions:

/opt/bin/virtualenv --system-site-packages venv2.7
. venv2.7/bin/activate
pip install -r requirements.txt 
pip install -I coverage
coverage run setup.py test
