I spoke in the general case based on decades of first-hand observations in RL. There are obviously always exceptions to any general pattern or effect. Also, not all projects have automated tests. Not all those with automated tests have 100% perfect coverage of everything that could possibly break. If anything I'd argue that the rise of unit test culture and TDD culture has actually increased the incidence of allowed sloppiness in some cases by folks having the mindset of, "I can deliver any diff I want. If no existing test failed, or the project has no tests, I did nothing wrong." This mindset too I've seen evidence of repeatedly. And there's nothing wrong with a person being new to programming. I can only reiterate the core point of my original comment to which you replied.
