No intellisense in Visual Studio 2010 Test Projects

Is there anything special about Test Projects that would cause intellisense not to work? This is my first experience with a test 开发者_JS百科project.

I think I turned off the option "Auto List members" somehow. Since this is a global option, I am not sure why it effected only my test project. Perhaps because the Test project was created last, just before the option was accidentally changed. (Theorizing.)

Thanks for your replies.
