"""
Unit tests for django-registration.

These tests assume that you've completed all the prerequisites for
getting django-registration running in the default setup, to wit:

1. You have ``registration`` in your ``INSTALLED_APPS`` setting.

2. You have created all of the templates mentioned in this
   application's documentation.

3. You have added the setting ``ACCOUNT_ACTIVATION_DAYS`` to your
   settings file.

4. You have URL patterns pointing to the registration and activation
   views, with the names ``registration_register`` and
   ``registration_activate``, respectively, and a URL pattern named
   'registration_complete'.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
