I think they were trying to run it under Mono, and it failed to complete most of the tests. Setting up IIS for a "real" test of ASP.NET MVC might be out of their intended scope.
We do have Windows tests (run exclusively on the Peak environment for Round 9), but most of the ASP.NET tests are not starting and passing validation correctly as-is. We'd like to get these fixed up along with all of the other tests that are not passing validation and running correctly. As you might expect, we have a never-ending game of whack-a-mole with so many frameworks in play, so we lean heavily on the community to assist. We'd love to get pull requests to help validate the existing .NET tests.
