TaskFlow
========

Testing and requirements
------------------------

Requirements
~~~~~~~~~~~~

Because this project has many optional (pluggable) parts like persistence
backends and engines, we decided to split our requirements into three
parts: - things that are absolutely required (you can't use the project
without them) are put into ``requirements-pyN.txt`` (``N`` being the
Python *major* version number used to install the package). The requirements
that are required by some optional part of this project (you can use the
project without them) are put into our ``tox.ini`` file (so that we can still
test the optional functionality works as expected). If you want to use the
feature in question (`eventlet`_ or the worker based engine that
uses `kombu`_ or the `sqlalchemy`_ persistence backend or jobboards which
have an implementation built using `kazoo`_ ...), you should add
that requirement(s) to your project or environment; - as usual, things that
required only for running tests are put into ``test-requirements.txt``.

Tox.ini
~~~~~~~

Our ``tox.ini`` file describes several test environments that allow to test
TaskFlow with different python versions and sets of requirements installed.
Please refer to the `tox`_ documentation to understand how to make these test
environments work for you.

Developer documentation
-----------------------

We also have sphinx documentation in ``docs/source``.
