title: Django unit test without creating test database every time I run
body: <p>Seems like "manage.py test" creates test database every time I run the test. Is there a way to prevent creating test database each time I run test but just truncate data (flush)?</p>
  
  <p>My tables are almost about 40 tables (even for single app, not the whole project), and makes me sick every time I run test.</p>
