Silverlight Unit Test Framework

A few weeks ago the Silverlight Toolkit was
released to extend the existing set of controls and components in Silverlight
2. I noticed that last week there was a
checkin to the toolkit to add the source code of the Silverlight unit test
framework. I know a few people have been
looking for a framework for doing unit testing with Silverlight applications
that they could customize for their uses.
Let me know if we've got what you're looking for now.
