Since Eric Hexter and I started the MvcContrib project, we’ve mandated a high test coverage.  If a patch comes without tests, we’d reject the patch. 

Given that MvcContrib exists for the purpose of supplementing a presentation library, ASP.NET MVC, you might think it’s not possible to achieve such a high percentage.

If you were ever curious about how this is done, I invite you to take a look at the project.  The project has 1058 tests at this point and the main MvcContrib.dll assembly has 99% test coverage. 

As an aside, when code is test-driven, the test coverage naturally falls out of this. 

By the way, Eric just released version 0.0.1.118 of MvcContrib to CodePlex.
