To populate a bunch of fake users run:

$ ./manage.py populate_random_people [10]

You can delete them later since they all have usernames that end in 'random'.

To run the unit tests::

$ ./manage.py test --settings=test_settings djangopeople newsletter welcome

If you're going to run a lot of unit tests you might want to NOT test the YouTube API every single time. To NOT test YouTube, set an environement variable called DONT_TEST_YOUTUBE::

$ export DONT_TEST_YOUTUBE=1
