I found the easiest way - just use the SQL dump for the test database. Create a database, fill it with fixtures and write to a file. Just call load_fixturesbefore you run the tests (or when you want to reset the database). This method can certainly be improved, but it is good enough for my needs.
import os
import unittest2
import tornado.database
settings = dict(
db_host="127.0.0.1:3306",
db_name="testdb",
db_user="testdb",
db_password="secret",
db_fixtures_file=os.path.join(os.path.dirname(os.path.abspath(__file__)), 'fixtures.sql'),
)
def load_fixtures():
"""Fixtures are stored in an SQL dump.
"""
os.system("psql %s --user=%s --password=%s < %s" % (settings['db_name'],
settings['db_user'], settings['db_password'], settings['db_fixtures_file']))
return tornado.database.Connection(
host=settings['db_host'], database=settings['db_name'],
user=settings['db_user'], password=settings['db_password'])
