Download

https://pypi.python.org/pypi/testing.postgresql

Install

Use pip:

$ pip install testing.postgresql

And testing.postgresql requires PostgreSQL server in your PATH.

Usage

Create PostgreSQL instance using testing.postgresql.Postgresql:

import testing.postgresql
from sqlalchemy import create_engine

# Lanuch new PostgreSQL server
with testing.postgresql.Postgresql() as postgresql:
    # connect to PostgreSQL
    engine = create_engine(postgresql.url())

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

    #
    # do any tests using PostgreSQL...
    #

# PostgreSQL server is terminated here

testing.postgresql.Postgresql executes initdb and postgres 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')

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()

    def tearDown(self):
        self.postgresql.stop()
