I am lucky enough to have two of my ObjectSharp colleagues running two separate Birds of a Feather sessions. Barry Gervin is hosting “Integrating Unit Testing tools and practices into the Software Development LifeCycle” on Sunday at 8:00 pm. Barry has been waist deep in unit testing design and implemention for quite a while now. Trust me that his knowledge is based on nicks, cuts and scars rather than book lernin'.
Also, Marcie Robillard (that's Datagrid Girl to the rest of the world) is hosting a BOF session on Wednesday. The topic is basically whatever her fertile mind dreams up. Be afraid. Be very afraid.
If you're attending TechEd, make sure you stop in and see what they have to say.
