"""
This module allows users to run tests for GIS apps that require the creation
of a spatial database. Currently, this is only required for PostgreSQL as
PostGIS needs extra overhead in test database creation.
In order to create a PostGIS database, the DATABASE_USER (or
TEST_DATABASE_USER, if defined) will require superuser priviliges.
To accomplish this outside the `postgres` user, you have a few options:
(A) Make your user a super user:
This may be done at the time the user is created, for example:
$ createuser --superuser <user_name>
Or you may alter the user's role from the SQL shell (assuming this
is done from an existing superuser role):
postgres# ALTER ROLE <user_name> SUPERUSER;
(B) Create your own PostgreSQL database as a local user:
1. Initialize database: `initdb -D /path/to/user/db`
2. If there's already a Postgres instance on the machine, it will need
to use a different TCP port than 5432. Edit postgresql.conf (in
/path/to/user/db) to change the database port (e.g. `port = 5433`).
3. Start this database `pg_ctl -D /path/to/user/db start`
(C) On Windows platforms the pgAdmin III utility may also be used as
a simple way to add superuser privileges to your database user.
The TEST_RUNNER needs to be set in your settings like so:
TEST_RUNNER='django.contrib.gis.tests.run_tests'
Note: This test runner assumes that the PostGIS SQL files ('lwpostgis.sql'
and 'spatial_ref_sys.sql') are installed in the directory specified by
`pg_config --sharedir` (and defaults to /usr/local/share if that fails).
This behavior is overridden if POSTGIS_SQL_PATH is set in your settings.
Windows users should set POSTGIS_SQL_PATH manually because the output
of `pg_config` uses paths like 'C:/PROGRA~1/POSTGR~1/..'.
Finally, the tests may be run by invoking `./manage.py test`.
