.. _javascript-fudge:
====================
Fudge For JavaScript
====================
Although `Ersatz <http://github.com/centro/ersatz/tree/master>`_ is a port of `Mocha <http://mocha.rubyforge.org/>`_ to JavaScript and that's pretty much what :ref:`Fudge <using-fudge>` is, I couldn't get Ersatz to work with one of my libraries because it uses Prototype. So I started porting Fudge to JavaScript. As of this writing it has only been partially implemented.
Install
=======
Download the :ref:`Fudge source distribution <fudge-source>` and copy ``javascript/fudge/`` to your webroot. To use it in your tests all you need is a script tag like this:
.. code-block:: html
<script src="fudge/fudge.js" type="text/javascript"></script>
If you want to run Fudge's own tests, then cd into the ``javascript/`` directory, start a simple webserver::
$ python fudge/testserver.py
and open http://localhost:8000/tests/test_fudge.html Take note that while Fudge's *tests* require jQuery, Fudge itself does not require jQuery.
Usage
=====
Refer to :ref:`using-fudge` in Python to get an idea for how to use the JavaScript version. As mentioned before, the JavaScript port is not yet fully implemented.
Here is a quick example:
.. code-block:: javascript
// if you had e.g. a session object that looked something like:
yourapp = {};
yourapp.session = {
set: function(key, value) {
// ...
}
}
yourapp.startup = function() {
yourapp.session.set('saw_landing_page',true);
};
// and if you wanted to test the startup() method above, then you could
// declare a fake object for a test:
var fake_session = new fudge.Fake('session').expects('set').with_args('saw_landing_page',true);
// patch your production code:
yourapp.session = fake_session;
// and run a test:
fudge.clear_calls();
yourapp.startup();
fudge.verify();
