Databases
The create_database() function
The create_database() function has the following prototype:
database = create_database(uri)
The uri parameter may be either a URI string or a URI object. The following URIs are examples of acceptable syntax:
backend:database_name backend://hostname/database_name backend://hostname:port/database_name backend://username:password@hostname/database_name backend://hostname/database_name?option=value backend://username@/database_name

Testing
It's easy to test that Storm features are working with new backends. There are base test classes in tests/store/database.py and tests/store/base.py which may be inherited by database-specific test cases. Look at other backends to get a feeling of how it works.
If these tests pass with a new backend, you may be pretty sure that Storm is working fine with the created backend.
