Mongo Box

Mongo Box helps starting and stopping sandboxed MongoDB instance from within a Python process. MongoDB instance is created with a temporary directory to store database file and is configured to be as lightweight as possible. It will choose a free port on localhost, so it will not interfere with default MongoDB processes. It is primarily expected to be used in unit tests and for prototyping concepts.

A typical use of a Mongo Box:

from mongobox import MongoBox

box = MongoBox()
box.start()

client = box.client() # pymongo client 
assert client.alive()

# do stuff with Mongo

box.stop()
assert not client.alive()

Nose

Mongo Box comes with a Nose plugin which is automatically installed. If used as a plugin, port of the running instance will be exported in environment variable MONGOBOX_PORT. This name can be overridden in settings.

The plugin exposes several configuration options. To see them, run:

nosetests --help

The options you are interested in start with --mongobox-.

Unit tests

For an easy unit tests integration there is a MongoTestCase class inherited from unittest.TestCase. It assumes tests are run from nosetests with --with-mongobox flag. MongoTestCases provides a pymongo client connected to the sandboxed mongo instance and a purge_database helper to clean up the database after every test:

from mongobox.unittest import MongoTestCase

class MyTest(MongoTestCase):
    def setUp(self):
        deploy_fixtures(self.mongo_client)

    def tearDown(self):
        self.purge_database()
