I think the main point with testable views is that the default asp.net view engine is completely coupled to the asp.net runtime. It was impossible to instantiate a view engine instance and render a view inside the test framework without creating a special app-domain in which to host the test. I had to wrestle with this just last week, it was a major pain in the ass to work around this limitation.
