======================
Running the Test Suite
======================

The easiest way to run the django-filter tests is to check out the source
code and create a virtualenv where you can install the test dependencies.
Django-filter uses a custom test runner to configure the environment, so a
wrapper script is available to set up and run the test suite.

.. note::

    The following assumes you have `virtualenv`__ and `git`__ installed.

__ https://virtualenv.pypa.io/en/stable/
__ https://git-scm.com

Clone the repository
--------------------

Get the source code using the following command:

.. code-block:: bash

    $ git clone https://github.com/carltongibson/django-filter.git

Switch to the django-filter directory:

.. code-block:: bash

    $ cd django-filter

Set up the virtualenv
---------------------

Create a new virtualenv to run the test suite in:

.. code-block:: bash

    $ virtualenv venv

Then activate the virtualenv and install the test requirements:

.. code-block:: bash

    $ source venv/bin/activate
    $ pip install -r requirements/test.txt

Execute the test runner
-----------------------

Run the tests with the runner script:

.. code-block:: bash

    $ python runtests.py


Test all supported versions
---------------------------

You can also use the excellent tox testing tool to run the tests against all
supported versions of Python and Django. Install tox, and then simply run:

.. code-block:: bash

    $ pip install tox
    $ tox


Housekeeping
------------

The ``isort`` utility is used to maintain module imports. You can either test
the module imports with the appropriate `tox` env, or with `isort` directly.

.. code-block:: bash

    $ pip install tox
    $ tox -e isort

    # or

    $ pip install isort
    $ isort --check-only --recursive django_filters tests

To sort the imports, simply remove the ``--check-only`` option.

.. code-block:: bash

    $ isort --recursive django_filters tests
