>>> from testcontainers.postgres import PostgresContainer
>>> import sqlalchemy
>>> with PostgresContainer("postgres:9.5") as postgres:
... engine = sqlalchemy.create_engine(postgres.get_connection_url())
... with engine.begin() as connection:
... result = connection.execute(sqlalchemy.text("select version()"))
... version, = result.fetchone()
>>> version
'PostgreSQL 9.5...'The snippet above will spin up a postgres database in a container. The get_connection_url() convenience method returns a sqlalchemy compatible url we use to connect to the database and retrieve the database version.
