Temporary PostgreSQL databases for Django and pytest

Use case

This pytest plugin can be used to test a Django application that uses PostgreSQL. It leverages the testing.postgresql module to setup a temporary PostgreSQL database server and injects the configuration for it into Django's settings. It is intended to be used together with pytest-django.

Requirements

testing.postgresql needs the postgresql server binary available.

How to use

To use, simply install the package in your testing environment and laod the django-testing-psotgresql plugin when running pytest (pytest normally auto-discovers it).

The plugin re-uses the configuration used by pytest-django.

By default, only the default database is setup. You can modify this by setting PYTEST_SETUP_DATABASES to a list of database aliases in your settings module. The list can contain strings, or tuples if you want some aliases to share the same database backend.
