+Testing nipype
+==============
+
+In order to ensure the stability of each release of Nipype, the project uses two
+continuous integration services: `CircleCI <https://circleci.com/gh/nipy/nipype/tree/master>`_
+and `Travis CI <https://travis-ci.org/nipy/nipype>`_.
+If both batteries of tests are passing, the following badges should be shown in green color:
+
+.. image:: https://travis-ci.org/nipy/nipype.png?branch=master
+  :target: https://travis-ci.org/nipy/nipype
+
+.. image:: https://circleci.com/gh/nipy/nipype/tree/master.svg?style=svg
+  :target: https://circleci.com/gh/nipy/nipype/tree/master
+
+
+Tests implementation
+--------------------
+
+Nipype testing framework is built upon `nose <http://nose.readthedocs.io/en/latest/>`_.
+By the time these guidelines are written, Nipype implements 17638 tests.
+
+To run the tests locally, first get nose installed::
+
+  pip install nose
+
+
+Then, after nipype is `installed in developer mode <../users/install.html#nipype-for-developers>`_,
+the tests can be run with the following simple command::
+
+  make tests
+
+
+Skip tests
+----------
+
+Nipype will skip some tests depending on the currently available software and data
+dependencies. Installing software dependencies and downloading the necessary data
+will reduce the number of skip tests.
+
+Some tests in Nipype make use of some images distributed within the `FSL course data
+<http://fsl.fmrib.ox.ac.uk/fslcourse/>`_. This reduced version of the package can be downloaded `here 
+<https://3552243d5be815c1b09152da6525cb8fe7b900a6.googledrive.com/host/0BxI12kyv2olZVUswazA3NkFvOXM/nipype-fsl_course_data.tar.gz>`_.
+To enable the tests depending on these data, just unpack the targz file and set the :code:`FSL_COURSE_DATA` environment
+variable to point to that folder.
+
+
+Testing Nipype using Docker
+---------------------------
+
+As of :code:`nipype-0.13`, Nipype is tested inside Docker containers. Once the developer
+`has installed the Docker Engine <https://docs.docker.com/engine/installation/>`_, testing
+Nipype is as easy as follows::
+
+  cd path/to/nipype/
+  docker build -f docker/nipype_test/Dockerfile_py27 -t nipype/nipype_test:py27
+  docker run -it --rm -v /etc/localtime:/etc/localtime:ro \
+                      -e FSL_COURSE_DATA="/root/examples/nipype-fsl_course_data" \
+                      -v ~/examples:/root/examples:ro \
+                      -v ~/scratch:/scratch \
+                      -w /root/src/nipype \
+                      nipype/nipype_test:py27 /usr/bin/run_nosetests.sh
+
+For running nipype in Python 3.5::
+
+  cd path/to/nipype/
+  docker build -f docker/nipype_test/Dockerfile_py35 -t nipype/nipype_test:py35
+  docker run -it --rm -v /etc/localtime:/etc/localtime:ro \
+                      -e FSL_COURSE_DATA="/root/examples/nipype-fsl_course_data" \
+                      -v ~/examples:/root/examples:ro \

+                      -w /root/src/nipype \
