Writing unit tests for classes that use DispatcherTimer

I just published an article on CodeProject which discusses how to write unit tests for classes that depend on DispatcherTimer to get their work done.

It seemed like a pretty straightforward task when I first tried to write a unit test for functionality which uses DispatcherTimer.  Wow, was I wrong!  It was actually a mind-bending experience, which required me to learn a lot about how WPF’s Dispatcher and DispatcherTimer work.  If you want to read more about what I learned along the way, here’s the link: http://www.codeproject.com/KB/WPF/UnitTestDispatcherTimer.aspx
