Custom coverage test runner doesn't create DB - database

Question

I'm using Django to create a Rest application.
I'm currently working on unit testing my application and instead of doing a coverage source=="." manage.py test myapp --settings="mycustomsettings" I decided to create a script that can start my tests and run them with a custom conf file and a coverage result.
Here is my tree :
|-- apps
| |-- __init__.py
| |-- me_api
| |-- me_auth
| |-- me_core
| |-- me_import
| `-- me_payment
|-- manage.py
|-- settings.py
|-- settings.pyc
|-- tests
| |-- coveragerunner.py
| |-- geodjango.db
| |-- __init__.py
| |-- local_settings.py
| `-- settings.py
|-- urls.py
`-- urls.pyc
I want to test the apps that are in the apps/ folder.
Here is my code (in tests/coveragerunner.py)
import os
import sys
from coverage import coverage
sys.path.append(os.path.join(os.path.dirname(__file__), "../"))
os.environ['DJANGO_SETTINGS_MODULE'] = 'tests.settings'
def main():
"""
Run tests and generates a coverage report.
"""
cov = coverage()
cov.erase()
cov.start()
from django.conf import settings
from django.test.utils import get_runner
TestRunner = get_runner(settings)
test_runner = TestRunner()
failures = test_runner.run_tests(['me_api'])
cov.stop()
if __name__ == '__main__':
main()
I'm using the geodjango.db which is a spatialite db as my default db for tests.
My script takes the settings for django but when I run it, it seems that the database is empty. I doesn't sync the DB on its own.
DatabaseError: no such table: me_auth_emailuser
Is there a way I can tell django to sync the db before running the tests or maybe did I do something wrong ? Thanks.
PS : When I used the manager.py there was no problem with the DB. (even with the spatialite db and the different settings source)

Answer 1

A quick and dirty solution goes as follows:
Set the database engine to sqlite, also for non-tests.
Make a syncdb to create a template for the test database.
Now the tests should work.
Don't forget to set the database engine back to postgesql.
