While at the MVP Summit, Carl and Richard sat down with Pratap Lakshman, Peli de Halleux and Nikolai Tillman to talk about automating unit testing in .NET. Originally a Microsoft Research Project, PEX is now part of Visual Studio 2015, and digs deep into the IL of your application to generate a huge variety of unit tests. The team also talks about some of the other cool projects they've built using the PEX engine, including CodeHunt, a tool using testing to teach you to program. Check out PEX on Microsoft Research, and get ready for Studio 2015!
