I do TDD which means that I write the MbUnit test first in an assembly called "Mcl.MyBusiness.Test". Then I write the code to make the test pass in "Mcl.MyBusiness". Ideally I would like to be able to select a new MbUnit test (before I have written the code that satisfies the test) and select a Resharper option that creates the new file(s) and class(es) in "Mcl.MyBusiness" and writes the method signatures out.
