Is there a library of default unit tests for .NET interface implementations?

Question

For example, I have a type which implements IDictionary, and I need test coverage to ensure that it does it properly. I just wondered if there is a repository of standard, reusable tests for this kind of thing anywhere; if there isn't, I might create one.

Answer 1

I doubt there's a publicly available .net one, but the Mono project might be a good place to start?

Whether they're testing "the contract" of the interface, or the specific implementation, I'm not sure, but there's certainly tests for the Dictionary class:
