Nose plugin with IPython and extension module support
=======================================================
This directory provides the key functionality for test support that IPython
needs as a nose plugin, which can be installed for use in projects other than
IPython.
The presence of a Makefile here is mostly for development and debugging
purposes as it only provides a few shorthand commands. You can manually
install the plugin by using standard Python procedures (``setup.py install``
with appropriate arguments).
To install the plugin using the Makefile, edit its first line to reflect where
you'd like the installation.
Once you've set the prefix, simply build/install the plugin with::
make
and run the tests with::
make test
You should see output similar to::
maqroll[plugin]> make test
nosetests -s --with-ipdoctest --doctest-tests dtexample.py
..

Combo testing example
=======================
This is a simple example that mixes ipython doctests::
In [1]: import code
In [2]: 2**12
Out[2]: 4096
with command-line example information that does *not* get executed::
$ mpirun -n 4 ipengine --controller-port=10000 --controller-ip=host0
and with literal examples of Python source code::
controller = dict(host='myhost',
engine_port=None, # default is 10105
control_port=None,
)
# keys are hostnames, values are the number of engine on that host
engines = dict(node1=2,
node2=2,
node3=2,
node3=2,
)
# Force failure to detect that this test is being run.
1/0
These source code examples are executed but no output is compared at all. An
error or failure is reported only if an exception is raised.
NOTE: the execution of pure python blocks is not yet working!
=====================================
Tests in example form - pure python
=====================================
This file contains doctest examples embedded as code blocks, using normal
Python prompts. See the accompanying file for similar examples using IPython
prompts (you can't mix both types within one file). The following will be run
as a test::
>>> 1+1
2
>>> print ("hello")
hello
More than one example works::
>>> s="Hello World"
>>> s.upper()
'HELLO WORLD'
but you should note that the *entire* test file is considered to be a single
test. Individual code blocks that fail are printed separately as ``example
failures``, but the whole file is still counted and reported as one test.

Tests in example form - IPython
=================================
You can write text files with examples that use IPython prompts (as long as you
use the nose ipython doctest plugin), but you can not mix and match prompt
