What is this?

A pytest plugin for tests that require a running RabbitMQ broker. It provides process and client fixtures.

How to use

The plugin contains two fixtures:

  • rabbitmq - it is a client fixture with function scope. After each test, it removes queues and exchanges created during the test to keep tests isolated and reliable.
  • rabbitmq_proc - a session-scoped fixture that starts a RabbitMQ instance at its first use and stops it at the end of the test session.

Simply include one of these fixtures in your test fixture list.

You can also create additional RabbitMQ client and process fixtures if you need to:

.. code-block:: python

from pytest_rabbitmq import factories

rabbitmq_my_proc = factories.rabbitmq_proc(
    port=None)
rabbitmq_my = factories.rabbitmq('rabbitmq_my_proc')

.. note::

Each RabbitMQ process fixture can be configured differently using fixture factory arguments.

Prerequisites

Install RabbitMQ on the machine where tests are executed. The plugin starts a local RabbitMQ process and uses rabbitmq-server and rabbitmqctl binaries.

By default, binary paths are set to typical Linux locations:

  • /usr/lib/rabbitmq/bin/rabbitmq-server
  • /usr/lib/rabbitmq/bin/rabbitmqctl

If your environment uses different paths, override them with fixture arguments, command-line options, or pytest.ini settings described below.

Quickstart: first test

Install the plugin:

.. code-block:: shell

pip install pytest-rabbitmq

Create a test that uses the built-in fixture:

.. code-block:: python

def test_rabbitmq_fixture_available(rabbitmq):
    assert rabbitmq is not None

Run your tests:

.. code-block:: shell

pytest -q

Configuration

You can define settings in three ways: 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``

    • RabbitMQ option
    • Fixture factory argument
    • Command-line option
    • pytest.ini option
    • Default
    • host
    • host
    • --rabbitmq-host

    • rabbitmq server path
    • server
    • --rabbitmq-server

    • $TMPDIR
    • Node name
    • node
    • --rabbitmq-node
    • rabbitmq_node
    • rabbitmq-test-{port}

Example usage:

  • Pass it as an argument in your own fixture.

    .. code-block:: python

      rabbitmq_proc = factories.rabbitmq_proc(port=8888)

  • Use the --rabbitmq-port command-line option when you run your tests.

    .. code-block::

      pytest tests --rabbitmq-port=8888

  • Specify your port as rabbitmq_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]
  rabbitmq_port = 8888
