[Moo] fireEvent question

[Greg Moeck]

I'm trying to write some integration/acceptance tests for an
application that I'm writing that uses Sortables, but I'm having some
trouble simulating the dragging. My plan was merely fire the events
for mousedown, movemouse, and and mouseup, but when I use
element.fireEvent, the Sortables start method fails, since a true
event is not passed in. I'm pretty sure it's just my lack of
understanding of javascript, but how would you go about doing
something like this?
