Writing Software

Keynote speech by David Heinemeier Hansson at RailsConf 2014.

He argues for system testing over unit testing and test driven development (TDD)

He proposes an alternative to the engineering driven holy grail of Coverage, Ratio and Speed metrics for testing and believes the objective should be clarity of the codebase.

DHH is a partner at Basecamp and creator of Ruby on Rails - the open source web framework that (amongst others) Twitter is built on.
