I see this a lot in AI slop, which I mostly get exposed to in the form of shitty pull requests.

You know when you're trying to explain Test-Driven Development to people and you want to explain how you write the simplest thing that passes the test and then improve the test, right? So you say "I want a routine that adds VAT onto a price, so I write a test that says £20+VAT is £24, and the simplest thing that can pass that test is just returning 24". Now you know and I know that the routine and its test will break if you feed it any value except £20, but we've proved we can write a routine and its test, and now we can make it more general.

Or maybe we don't care and we slap a big TODO: make this actually work on there because we don't need it to work properly now, we've got other things to do first, and every price coming up as £20+VAT is a useful indicator that we still have to make other bits work. It doesn't matter.

The problem is that AI slop code "generators" will just stop at that point and go "THERE LOOK IT'S DONE AND IT'S PERFECT!" and the people who believe in the usefulness of AI will just ship it.
