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 print(client.server_info()) # do stuff with Mongo box.stop() try: client.server_info() except: print('Mongo instance is stopped')
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
The plugin exposes several configuration options. To see them, run:
The options you are interested in start with
nose2.cfg should look similar to this:
[unittest] plugins = mongobox.nose2_plugin [mongobox] # Optionally specify the path to the mongod executable # bin = # Optionally specify the port to run mongodb on # port = # Optionally enable mongodb script engine # scripting = True # Path to database files directory. Creates temporary directory by default # dbpath = # Optionally store the mongodb log here (default is /dev/null) # logpath = # Optionally preallocate db files # prealloc = True # Which environment variable port number will be exported to port_envvar = MONGOBOX_PORT
For an easy unit tests integration there is a
unittest.TestCase. It assumes tests are run from
MongoTestCases provides a
connected to the sandboxed mongo instance and a
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()
Get it from PyPi:
pip install mongobox
Get it from GitHub:
pip install https://github.com/theorm/mongobox.git
MongoBox is based on
mongonose nose plugin by Kapil Thangavelu.
