DHH’s point wasn’t that the tests were bad, but that TDD leads to ‘test-induced damage’. Having seen many code-bases written with unthinking TDD, I’d tend to agree.
The wonderful quality of such an assertion, however, is that it’s what Karl Popper would call a falsifiable statement. I also believe that it’s possible to falsify it, in the sense that it’s possible to use TDD to arrive at code that has no test-induced damage. As it turns out, this is much easier to do with functional programming than with object-oriented programming.
Most of this episode discussed unit testing in an object-oriented context, I think. Some practices and techniques stay the same in functional programming, but others differ. One of the most amazing changes happens when you start using property-based testing instead of example-based testing.
This is still unit testing, in my opinion, because it doesn’t touch boundaries (I don’t agree with Jay’s lack of definition of the term), but it’s another way of looking at testing. Some of the opinions put forth in this episode, such as only expecting literals, conflict with this sort of technique, though.
It’s hardly ‘early days’, though, as QuickCheck has been around since 1999.
CyclingTips Podcast, Episode 17: David Walsh on Armstrong, Sky, Froome and the Wiggins TUEs | CyclingTips
David Walsh is the chief sports writer at the Sunday Times and a journalist best known in cycling circles as the man who helped expose Lance Armstrong. Having viewed Armstrong’s 1999 Tour de France return with great scepticism, Walsh spent many years trying to show that the Texan had doped his way to what would amount to seven Tour de France victories.
In early 2013, in the face of mounting evidence of his past transgressions, Armstrong appeared on the Oprah Winfrey Show to admit to doping throughout his career. More than 13 years after he first started questioning Armstrong’s performances, Walsh had been proven right.
Walsh was recently in Melbourne for the Sports Writers Festival, to speak about his time spent chasing the Armstrong story and CyclingTips’ Australian editor Matt de Neef caught up with Walsh during his visit. In this wide-ranging interview Walsh reflects on what it was like breaking and following a story as big as Armstrong’s, what he learned from his time embedded with Team Sky in 2013, and what he thinks about the recent Fancy Bear leaks of Bradley Wiggins therapeutic use exemption (TUE) forms and what they say about Sky, Wiggins and three-time Tour de France winner Chris Froome.

Sure, we all pay lip service to the Madisonian system of checks and balances. But as one legal scholar argues, presidents have been running roughshod over the system for decades. The result? An accumulation of power that’s turned the presidency into a position the founders wouldn’t have recognized.
The U.S. president is often called the "leader of free world." But if you ask an economist or a Constitutional scholar how much the occupant of the Oval Office matters, they won’t say much. We look at what the data have to say about measuring leadership, and its impact on the economy and the country.
From Goleta, California we welcome Tom Anhalt. By day he works as a Mechanical Engineer, designing endoscopic video devices. For a hobby, he provides some of the most useful and interesting information on all things related to cycling tires and practical aerodynamics. Choosing the right tire can (and likely will) make you a faster cyclist, and Tom is nice enough to join us today to share what he has learned (so far). You can and should read Tom’s excellent blog at http://bikeblather.blogspot.com/, and follow Tom on Twitter @tanhalt.
