testing.postgresql 0.1.0

automatically setups a postgresql instance in a temporary directory, and destroys it after testing

testing.postgresql automatically setups a postgresql instance in a temporary directory, and destroys it after testing

Install

Use easy_install (or pip):

$ easy_install testing.postgresql

And testing.postgresql requires PostgreSQL server in your PATH.

Usage

Create PostgreSQL instance using testing.postgresql.Postgresql:

import testing.postgresql
postgresql = testing.postgresql.Postgresql()  # Lanuch new PostgreSQL server

# connect to PostgreSQL
from sqlalchemy import create_engine
engine = create_engine(postgresql.url())

# if you use postgresql or other drivers:
#   import psycopg2
#   db = psycopg2.connect(**postgresql.dsn())

#
# do any tests using PostgreSQL...
#

del postgresql                     # Terminate PostgreSQL server

testing.postgresql.Postgresql executes initdb and postmaster on instantiation. On deleting Postgresql object, it terminates PostgreSQL instance and removes temporary directory.

If you want a database including tables and any fixtures for your apps, use copy_data_from keyword:

# uses a copy of specified data directory of PostgreSQL.
postgresql = testing.postgresql.Postgresql(copy_data_from='/path/to/your/database')

You can specify parameters for PostgreSQL with my_cnf keyword:

# boot PostgreSQL server without socket listener (use unix-domain socket)
postgresql = testing.postgresql.Postgresql(my_cnf={'skip-networking': None})

For example, you can setup new PostgreSQL server for each testcases on setUp() method:

import unittest
import testing.postgresql

class MyTestCase(unittest.TestCase):
    def setUp(self):
        self.postgresql = testing.postgresql.Postgresql(my_cnf={'skip-networking': None})
