Hi.
What is the best practice to create an engine in a test suite?
In one of my projects I was using sqlalchemy.testing module and the sqla
nose plugin, but these are no more available in the latest versions.
I have checked the alembic source code, and it have some private code
for parsing test.cfg configuration file and searching engine
configuration given an alias.
However I would like to avoid having to write such a code for every
project that use SQLAlchemy.
My current solution is to have this code in the test/__init__.py module:
## begin __init__.py
import ConfigParser
from sqlalchemy import create_engine
__all__ = ['create_testing_engine']
config = ConfigParser.ConfigParser()
config.read(['test.cfg'])
def create_testing_engine(alias=None):
if alias is not None:
url = config.get('db', alias)
else:
# Return the first engine defined
config_data = config.items('db')
if not config_data:
# Fall back to sqlite in memory database
url = 'sqlite://'
else:
url = config_data[0][1]
return create_engine(url)
## end __init__.py
Thanks Manlio Perillo
