title: Saving django test database in a fixture?
body: <p>I have a production database that contains a large set of data. I'd like to use some of that data for running unit tests, but taking all of it causes a fairly lengthy period at the start of the testing process to build the database., which I'd like to avoid.</p>
  
  <p>I've created a test database using the <code>manage.py testserver</code> command, then deleted all the data I didn't want to be included through the admin interface. How do I create a fixture of the data that remains in the default test database?</p>
