A fixture for creating PostgreSQL clusters and databases, and tearing them down again, intended for use during development and testing.
Project description
A Python fixture for creating PostgreSQL clusters and databases, and tearing them down again, intended for use during development and testing.
For more information see the Launchpad project page.
Getting started
Use like any other fixture:
from contextlib import closing
from postgresfixture import ClusterFixture
def test_something(self):
cluster = self.useFixture(ClusterFixture("db"))
cluster.createdb("example")
with closing(cluster.connect("example")) as conn:
...
cluster.dropdb("example") # Optional.
This will create a new cluster, create a database called “example”, then tear it all down at the end; nothing will remain on disk. If you want the cluster and its databases to remain on disk, pass preserve=True to the ClusterFixture constructor.
From the command line
Once this package is installed, you’ll have a postgresfixture script. Alternatively you can use python -m postgresfixture to achieve the same thing. Use --help to discover the options available to you.
