My experience, while nowhere close to being representative of the aviation industry at large, has been that large industrial companies are somewhat schizophrenic in this regard. I often find myself appreciating, for example, the care that somebody put into their automated build tools so that my unexpected corner case (which I originally expected to break things) actually worked the first time without a hiccup. Yet later in the same day I will be cursing the awful, terribly broken two decade old version control system that the same company is paying enormous sums of money to license. TDD is one of the approaches that I advocate for often, though not the extreme versions that some people advocate for. Some people get it, while others think it's more efficient to wait until the last few days of a waterfall(ish) process before running comprehensive tests (because "testing costs money"). The panic that ensues when they discover a major problem days before a big deadline is never very pretty.
