Start an ephemeral postgres instance for easy testing

Project description


Build Status

ephemeral-postgres is a python package for easily setting up, testing, and finally tearing down postgres instances. It can be easily integrated in most test suites but has been primarily used with pytest.


pip install ephemeral-postgres


import ephemeral_postgres
import psycopg2

with ephemeral_postgres.postgres() as uri:
    con = psycopg2.connect(uri)
    cur = con.cursor()
    cur.execute('select * from pg_database')
    for row in cur.fetchall():

Alternatively, if you would like to run an external Postgres server, you can override ephemeral_postgres from starting a new instance by setting the environment variable EPHEMERAL_POSTGRES_URI accordingly. For example:

export EPHEMERAL_POSTGRES_URI="postgresql://postgres:postgres@localhost:5432/postgres"
python "import ephemeral_postgres; print(ephemeral_postgres.postgres()[0])"


pip install -e .[test]

# run unit tests
