I am running tests on a project I've been assigned to. Everything is triggered by calling tox. Default tests run with nose, which adds a coverage report, this is the command that tox calls:
django-admin test -s
and settings file has this configuration for nose:
NOSE_ARGS = [
'--with-coverage',
'--cover-erase',
'--cover-package=app_name',
'--cover-inclusive'
]
This is the report that's shown while running nose with tox:
Name Stmts Miss Cover

Now, as you can see, certain files were ignored by nose report, but shown by coverage, like app_name/services/account_service.py. And since that file contains feature code it should be shown on report.
The interesting thing here is that, as far as I know, both libraries: nose and coverage are generating their reports from the same report file .coverage
I guess this is a default nose behavior. I'm not very familiar with nose so perhaps anyone can tell me why this difference of behavior happens.
