Michelle,
This is a really nifty strategy. Thanks for sharing it with the list.
One quick comment below...

I've spent a couple hours today trying to get the table of contents
tests passing and now that they are working I thought I'd share what
I learned (thanks Antranig). The problem I ran into was that the
code I was testing had an AJAX call in it. I needed to run the test
after the AJAX call returned. Our general test writing pattern will
not work in this case, instead I used our event system to run the
test. This is not a perfect solution since the test knows an
implementation detail of the code (that there is an AJAX call) but I
couldn't think of a better way to write this.
Actually, I don't think this does reveal an implementation detail to
the test code, or to anyone else for that matter. You've encapsulated
this into a standard Infusion event ("myEvent"), so the contract is
clear. The specifics of the AJAX call, however, don't leak out into
user code. This is a good thing.
Plus, generally users of this code would generally want to know about
the fact that an AJAX call is being made so that they can use the
event wisely.

If you are going to use this strategy for code you are testing, it
is important to remember that the test itself needs to start inside
the event handler. This pattern looks like this:
(function ($) {
$(document).ready(function () {
var tests = new jqUnit.TestCase("My Tests");
var myEventHandler = function () {
tests.test("My Test", function () {
assertTrue("this is a test", true);
});
};
var options = {
listeners: {
myEvent: myEventHandler
}
};
fluid.myComponent(container, options);
});
})(jQuery);
