Unit tests on MVC validation

Question

How can I test that my controller action is putting the correct errors in the ModelState when validating an entity, when I\'m using DataAnnotation validation in MVC 2 Previe

Answer 1

I was researching this today and I found this blog post by Roberto Hernández (MVP) that seems to provide the best solution to fire the validators for a controller action during unit testing. This will put the correct errors in the ModelState when validating an entity.
