Microsoft PEX and Moles

Microsoft Research is currently beta testing a couple new frameworks that can make unit testing your code a breeze. Pex is a testing tool that analyzes code and generates unit tests. Moles is a framework that isolates code with dependencies on other application layers or frameworks. With just a few mouse clicks, you can generate suites of tests against code that previously may have been difficult or impossible to test.

Tonight I'll be giving a presentation on these technologies at the Nashville .NET User Group. For anyone who can't make it you can watch and discuss it in my Google Hangout. I'm hoping to post a video of the presentation to this blog within the next couple weeks. I'll also be giving a similar presentation and Code PaLOUsa on March 17th. Below are links to the demo solutions and Prezi used in the presentation.
