Developer Documentation
=======================

Development Workflow
--------------------

* Fork from github
* Develop on your fork
* Test locally
* Make a pull request

Before making a pull request, make sure that your fork is up to date and that all the
tests pass locally. This will make it less likely that your pull request will get
rejected by making breaking chages or by failing the test requirements.

Running the tests
-----------------

The tests require that you have cloned the repository, since the test code is
not distributed in the package. It is recommended to use ``nosetests`` for
this. There are two options:

Use the provided ``Makefile`` to run the tests using ``make``:

.. code-block:: bash

    $ git clone https://github.com/BlueBrain/NeuroM.git
    $ cd NeuroM
    $ make test

This runs ``pep8``, ``pylint`` and the unit tests in sequence.

This method takes care of
installing all extra dependencies needed for running the tests, diagnosing the results,
performing linting on the source code. These dependencies are installed into a
``virtuanelv`` named ``neurom_test_venv``:

The ``Makefile`` also has targets for running only pylint and pep8 individually:

.. code-block:: bash

        $ make lint       # runs pep8 and pylint if that succeeds
        $ make run_pep8   # run only pep8
        $ make run_pylint # run only pep8


Note that you can also install the test dependencies and run the tests inside of your
own virtualenv:

.. code-block:: bash

    (nrm)$ pip install -r requirements_dev.txt

This installs the following packages into your ``virtualenv``
unless they are already installed:

.. literalinclude:: ../../requirements_dev.txt
    :lines: 29-36

Then, run the tests manually in the ``virtualenv``. For example,

.. code-block:: bash

    (nrm)$ nosetests -v --with-coverage --cover-min-percentage=100 --cover-package neurom

.. warning::

    To ensure that the test requirements are the same as those run in continuous
    integration, you should run the tests using the ``make test`` command. This is the
    same command used in continuous integration. Failure to pass means will result in
    a pull request being rejected.

Python compatibility
--------------------

We test the code against Python 2.6, 2.7, 3.5.
