Jonathan 'Peli' de Halleux, is the original author of the MbUnit framework. After working 2 years in the CLR in Redmond, WA, Peli moved to the Foundations for Software Engineering group in Microsoft Research.Peli is currently developing a new test tool, Pex (http://research.microsoft.com/pex). Pex will let you write parameterized tests, similarly to [CombinatorialTest] or [RowTest] *but* the tool will find the relevant input to acheive maximum coverage with a minimal test suite.
