Hey!

If you are new to testing WPF applications or to testing in general, the WPF team has just released a new version of their quality guide. It has a lot of useful information and resource links related to testing in general and testing of GUI applications. You can either look at an online version or download a doc file.  The WPF team also has a community website with additional information and resources including a discussion mailing list. They have provided means for you to send your feedback about the sites or the quality guide directly to them too. Enjoy!
