45: David Heinemeier Hansson - Software Development and Testing, TDD, and exploratory QA

Spela upp

David Heinemeier Hansson is the creator of Ruby on Rails, founder & CTO at Basecamp (formerly 37signals). He's a best selling author, public speaker, and even a Le Mans class winning racing driver.

All of that, of course, is awesome. But that's not why I asked him on the show. In 2014, during a RailsConf keynote, he started a discussion about damage caused by TDD. This was followed by a few blog posts, and then a series of recorded hangouts with Martin Fowler and Kent Beck. This is what I wanted to talk with David about; this unconventional yet practical and intuitive view of how testing and development work together.

It's a great discussion. I think you'll get a lot out of it.

If you use the link [testandcode.com/pycharm](http://testandcode.com/pycharm), you can try PyCharm Professional for free for 3 months. This offer is only good until Sept 1, so don't forget. Plus using the link (I'll also have it in the show notes) lets PyCharm know that supporting Test & Code is a good thing.
