Super-smart-guy Peli disappeared into MSR a while ago to work on Pex, an exploratory testing framework for .NET. There had been lots of teaser blog entries, a few conference appearances, chats with Hanselman, a video or two but no release, until last monday when Pex 0.5 was released. Testing Supremo Bruce McLeod is planning a series of posts explaining all of this tentatively titled “the Joy of Pex”. He then plans a follow-up article “how to explain to your spouse why you're staying up a night reading something on the internet called 'The Joy of Pex'”. Can't wait.
