I feel like some of these comments are just reading the title and immediately posting their disagreement. I'm with you, he says he writes integration tests himself. There's nothing controversial about this post, it's actually pretty interesting.
After reading the article, I thought the person posting to HN had either misunderstood it or misappropriated it for his own agenda - but then I saw that it was apparently posted by the author himself.
There's a challenge finding the right headline when posting to HN. My last few posts had very literal headlines and went nowhere. I amped this headline up a bit while making sure it was still honest and, looky here, it got more attention. Now I have to decide how I feel about the difference.
