Working without setuptools / from source
==========================================
If you have a checkout_ or a tarball_ it is actually not neccessary to issue
``setup.py`` commands in order to use py lib and its tools. You can
simply add the root directory to ``PYTHONPATH`` and ``py/bin`` or
``py\bin\win32`` to your ``PATH`` settings.
There are also helper scripts to set the environment
on windows::
c:\\path\to\checkout\py\env.cmd
and on linux/osx you can add something like this to
your shell initialization::
eval `python ~/path/to/checkout/py/env.py`
both of which which will get you good settings
for ``PYTHONPATH`` and ``PATH``.
Note also that the command line scripts will look
for "nearby" py libs, so if you have a layout like this::
mypkg/
subpkg1/
tests/
tests/
py/
then issuing ``py.test subpkg1`` will use the py lib
from that projects root directory.

Working with multiple py lib versions / svn externals
=======================================================
If you happen to have multiple versions of the py lib
around or you ship the py lib as an svn-external to
then you might want to use py lib scripts more directly.
For example if you have a project layout like this::
mypkg/
subpkg1/
tests/
tests/
py/ # as svn-external, could be specific tag/version
then you want to make sure that the actual local py lib is used
and not another system-wide version. For this you need to add
``py/bin`` or ``py\bin\win32`` respectively to your system's PATH settings.
You can do this by executing (on windows) a script to set the environment::
c:\\path\to\checkout\py\env.cmd
or on linux/osx you can add something like this to your shell

jskit contains infrastructure and in particular a py.test plugin to enable running tests for JavaScript code inside browsers directly using py.test as the test driver. Running inside the browsers comes with some speed cost, on the other hand it means for example the code is tested against the real-word DOM implementations.
The approach also enables to write integration tests such that the JavaScript code is tested against server-side Python code mocked as necessary. Any server-side framework that can already be exposed through WSGI (or for which a subset of WSGI can be written to accommodate the jskit own needs) can play along.
jskit also contains code to help modularizing JavaScript code which can be used to describe and track dependencies dynamically during development and that can help resolving them statically when deploying/packaging.
jskit depends on simplejson. It also uses MochiKit - of which it ships a version within itself for convenience - for its own working though in does not imposes its usage on tested code.
jskit was initially developed by Open End AB and is released under the MIT license.
