Why am I receiving this error about app name in my django unittest?

When running manage.py test, I receive the following error.

======================================================================
ERROR: Failure: RuntimeError (Model class app.pipeline.models.Product doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.)
----------------------------------------------------------------------

    "INSTALLED_APPS." % (module, name)
RuntimeError: Model class app.pipeline.models.Product doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

settings.py 

INSTALLED_APPS = [
    'pipeline.apps.PipelineConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django_nose',
    'bootstrap3',
    'bootstrap_pagination',
    'mobilereports',
    'rest_framework',
    'api'
]

This error only gets thrown when I run tests, but does not in any way affect the performance of the website (this is live in production right now).

This project was inherited, and the project or app name may have been previously changed (not sure if the error might be related to this).

The reason for this error message has most likely to do with you having an __init__.py in the same folder as the manage.py. If you remove the __init__.py, the test runner shouldn't complain anymore.

For more info see this comment in the Django bugtracker

Adding this here, as I came by this question as I was looking for an answer to the problem.
