All of this. However, the issue is that coding the paper is only _one_ (and often not the biggest) step from idea to published paper. Worse, once the paper is published typically nobody cares for your code and whether its test coverage is x% (at least here in the social sciences).

I'm not saying that I support this (quite the opposite), but that's the outcome of our publish-fast-and-frequently-culture to get tenure.

Nota bene, I observe an increasing number of exceptions to this rule in my field, but still a minority.
