How can I specify a database for Django Tests to use instead of having it build it every time?

I want to be able to use an existing test database to run my tests against and not have Django create and delete a database every time I want to run the tests. Is this possible开发者_如何学Python?

It's possible, here is a way :

1) Define your own test runner look here to see how.

2) For your custom test runner look in the default test runner, you can just copy and past the code and just comment this line : connection.creation.destroy_test_db(old_name, verbosity) which is responsible for destroying the test database, and i think you should put the connection.creation.create_test_db(..) line in a try except something like this maybe:

try:
    # Create the database the first time.
    connection.creation.create_test_db(verbosity, autoclobber=not interactive) 
except ..: # Look at the error that this will raise when create a database that already exist
    # Test database already created.
    pass 

3) Bound TEST_RUNNER in setting.py to your test runner.

4) Now run your test like this: ./manage.py test

Who are using Django >= 1.8

python manage.py test --keepdb

--keepdb Preserves the test database between test runs. This has the advantage of skipping both the create and destroy actions which can greatly decrease the time to run tests, especially those in a large test suite. If the test database does not exist, it will be created on the first run and then preserved for each subsequent run. Any unapplied migrations will also be applied to the test database before running the test suite.
