should we test that this is the right type in the task manager as well?

[Charlie Reis, 2010/12/02 01:45:43]

Good idea.  The last one is actually a TabContentsResource and not an
ExtensionResource, so it's worth showing that in the test.

I also found a way to test the title prefix.  That means I could test the app
prefix as well-- do you know if there are any packaged apps in the test
directory I could install, or will I need to write a new one?
