That's irrelevant. There are multiple reasonable possibilities here. Saying "Do X, now get on with coding" as if X is somehow obviously the right answer is a very dangerous attitude. The original article might not have mentioned those kinds of testing explicitly, but still, professionals decide among various choices being considered based on merit, not personal preference.
I find your comment odd (in that I am confused by it). The top comment (which you seem to take issue with) isn't any more useful to anyone than the OP itself. I took it as a bit tounge-in-cheek. You state that professionals make decisions based on merit rather than personal preference and yet the OP did the exact opposite. So neither the OP nor top-commenter are taking the 'professional' approach here.
FWIW I agree with pretty much everything you said in your previous comment (although perhaps not the first sentence).
EDIT: Or perhaps his last sentence irritated you? If he'd omitted "Now, get back to writing code!" would you still feel the same?
I think we just interpreted the original comment differently. I didn't sense any humour in the point being made, only in the flippant final line, and I strongly disagreed with the basic point regardless of anything related that the original article did or didn't mention. If I misunderstood then the poster has my apologies.
