DDD7 Session Video – Microsoft Pex – The future on unit testing?

As you may recall, in November I presented at DDD7 in Reading, UK about Pex and the future of unit testing.

Is unit testing about to have a major change? Pex is a project from Microsoft Research which automatically generates a traditional unit testing suite with high code coverage from hand-written parameterised unit tests. In this session, Ben explores the Pex framework, explaining the approach the framework takes and how it computes the test inputs based on your programs execution. Ben demonstrates how to use the framework and how it could potentially change the way we write unit tests.

At the time the session was recorded, with a little help from Liam (thank you!), the session is now available online. I hope you enjoy it!

DDD7 Slides and Code – Pex – The future of unit testing


Yesterday, Developer Day (DDD) 7 was held at Microsoft UK. I delivered a presentation on Pex, a new project from Microsoft Research. I provided an introduction into Pex, the problem it attempts to solve, how Pex works in the real world and finally where I think the future of unit testing and Pex is heading.

I had a great day and I was very happy with my session – the demo gods where with me. Based on tweets via twitter and other comments, it was generally well received.  Thank you to everyone who attended, when feedback opens on the website please be sure to leave your comments as they are all taken into account.

DDD7 also had Channel 9 recording all the sessions, if you couldn’t attend – don’t worry, hopefully the videos will be online in the new year!

DDD7 – Microsoft Pex – The future of unit testing?

I received my email last night confirming that my Microsoft Pex session for DDD7 has been selected by you, the voting ‘potential’ attendees! I’m honoured that the session has been voted for, DDD is an amazing conference (registration is free, opening very soon) and based on the tweets from various people, there should be some great sessions.

If you would like a quick overview of Pex before DDD, then I suggest you read my MSDN Flash article.
