MongoDB process and client fixtures plugin for py.test.

Project Description


Package status

What is this?

This is a pytest plugin, that enables you to test your code that relies on a running MongoDB database. It allows you to specify fixtures for MongoDB process and client.

How to use

Plugin contains two fixtures

  • mongodb - it’s a client fixture that has functional scope, and which cleans MongoDB at the end of each test.
  • mongo_proc - session scoped fixture, that starts MongoDB instance at the first use and stops at the end of the tests.

Simply include one of these fixtures into your tests fixture list.

You can also create additional MongoDB client and process fixtures if you’d need to:

from pytest_mongo import factories

mongo_my_proc = factories.mongo_proc(
    port=None, logsdir='/tmp')
mongo_my = factories.mongodb('mongo_my_proc')


Each MongoDB process fixture can be configured in a different way than the others through the fixture factory arguments.


You can define your settings in three ways, it’s fixture factory argument, command line option and pytest.ini configuration option. You can pick which you prefer, but remember that these settings are handled in the following order:

  • Fixture factory argument
  • Command line option
  • Configuration option in your pytest.ini file
What Fixture factory argument Command line option pytest.ini option Default
Path to mongodb exec executable –mongo-exec mongo_exec /usr/bin/mongod
MongoDB host host –mongo-host mongo_host
MongoDB port port –mongo-port mongo_port random
Path to store logs logsdir –mongo-logsdir mongo_logsdir $TMPDIR
Additional parameters params –mongo-params mongo_params  

Example usage:

  • pass it as an argument in your own fixture

    mongo_proc = factories.mongo_proc(port=8888)
  • use --mongo-port command line option when you run your tests

    py.test tests --mongo-port=8888
  • specify your directory as mongo_port in your pytest.ini file.

    To do so, put a line like the following under the [pytest] section of your pytest.ini:

    mongo_port = 8888



  • [enhancement] removed depdendency


  • [enhancements] set executor timeout to 60. By default mirakuru waits indefinitely, which might cause test hangs


  • [feature] - migrate usage of getfuncargvalue to getfixturevalue. require at least pytest 3.0.0


  • [feature] defaults logs dir to $TMPDIR by default
  • [feature] run on random port by default (easier xdist integration)
  • [feature] add command line and ini option for: executable, host, port, params and logsdir
