These are listed in ``dev-requirements.txt`` and they +can be installed in a `virtualenv`_ using `pip`_. Once you've installed the +dependencies, install ``cryptography`` in ``editable`` mode. For example: + +.. code-block:: console + + $ # Create a virtualenv and activate it + $ pip install --requirement dev-requirements.txt + $ pip install --editable . + +You are now ready to run the tests and build the documentation. + +Running Tests +~~~~~~~~~~~~~ + +``cryptography`` unit tests are found in the ``tests/`` directory and are +designed to be run using `pytest`_. `pytest`_ will discover the tests +automatically, so all you have to do is: + +.. code-block:: console + + $ py.test + ... + 62746 passed in 220.43 seconds + +This runs the tests with the default Python interpreter. + +You can also verify that the tests pass on other supported Python interpreters. +For this we use `tox`_, which will automatically create a `virtualenv`_ for +each supported Python version and run the tests. For example: + +.. code-block:: console + + $ tox + ... + ERROR: py26: InterpreterNotFound: python2.6 + py27: commands succeeded + ERROR: pypy: InterpreterNotFound: pypy + ERROR: py32: InterpreterNotFound: python3.2 + py33: commands succeeded + docs: commands succeeded + pep8: commands succeeded + +You may not have all the required Python versions installed, in which case you +will see one or more ``InterpreterNotFound`` errors. + + +Explicit Backend Selection +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +While testing you may want to run tests against a subset of the backends that +cryptography supports. Explicit backend selection can be done via the +``--backend`` flag. This flag should be passed to ``py.test`` with a comma +delimited list of backend names. To use it with ``tox`` you must pass it as +``tox -- --backend=openssl``. + +Building Documentation +~~~~~~~~~~~~~~~~~~~~~~ + +``cryptography`` documentation is stored in the ``docs/`` directory. It is +written in `reStructured Text`_ and rendered using `Sphinx`_. + +Use `tox`_ to build the documentation. For example: + +.. code-block:: console + + $ tox -e docs + ... + docs: commands succeeded + congratulations :) + +The HTML documentation index can now be found at +``docs/_build/html/index.html``. + +.. _`pytest`: https://pypi.python.org/pypi/pytest +.. _`tox`: https://pypi.python.org/pypi/tox +.. _`virtualenv`: https://pypi.python.org/pypi/virtualenv +.. _`pip`: https://pypi.python.org/pypi/pip +.. _`sphinx`: https://pypi.python.org/pypi/Sphinx +.. _`reStructured Text`: http://sphinx-doc.org/rest.html -- cgit v1.2.3
