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:


.. code-block:: python

from pytest_mongo import factories

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

.. note::

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

Configuration
=============

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 | 127.0.0.1 |
+-----------------------+--------------------------+---------------------+-------------------+-----------------+
| 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

.. code-block:: python

mongo_proc = factories.mongo_proc(port=8888)

* use ``--mongo-port`` command line option when you run your tests

.. code-block::

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``:

.. code-block:: ini

[pytest]
mongo_port = 8888
