I’m pleased to announce that SpecsFor.com is now live. I’ve also shipped a new version of SpecsFor that simplifies the painful task of creating multiple mocks of the same type for injection into IEnumerable parameters.
@dpeterson, the biggest thing that sets SpecsFor apart from other frameworks is its intent. It's designed specifically to address common pain points that come up while practicing BDD/TDD in .NET, enabling developers to focus on the parts of their tests that matter. It takes care of as many of the common repetitive concerns as possible while still remaining flexible enough to accommodate most common testing styles and needs.
I have considered Gherkin support similar to SpecFlow, but it's pretty low on my priority list at the moment.
