As you likely heard, we have released the source code for all of the Silverlight controls as well as almost 2,000 of our own unit tests. Included with in this is a jewel... A unit testing framework for Silverlight. It is very powerful to have this feature so early in the develop of a new platform such as this.
Shawn Burke has a nice post walking you through the source code and test suite.
Jeff Wilcox has a post detailing the Unit Testing framework he built for Silverlight 2.
I'd love to hear what you think... Have you looked around in the source and test code base yet? Have you tried out the unit testing framework? any thoughts\feedback?
thanks and enjoy!
